ADC-05596 v13.0 05/22
Intended Use
This neurostimulation system is designed to deliver low-intensity electrical impulses to nerve structures. The system is intended to be used with leads and associated extensions that are compatible with the system.
Indications For Use
Abbott Medical spinal cord stimulation (SCS) systems are indicated as an aid in the management of chronic, intractable pain of the trunk and/or limbs, including unilateral or bilateral pain associated with the following: failed back surgery syndrome, nonsurgical back pain (without prior surgery and not a candidate for back surgery), and diabetic peripheral neuropathy of the lower extremities.
Contraindications
This system is contraindicated for patients who are unable to operate the system or who have failed to receive effective pain relief during trial stimulation.
MRI Safety Information
Some models of this system are Magnetic Resonance (MR) Conditional, and patients with these devices may be scanned safely with magnetic resonance imaging (MRI) when the conditions for safe scanning are met.
For more information about MR Conditional neurostimulation components and systems, including equipment settings, scanning procedures, and a complete listing of conditionally approved components, refer to the MRI procedures clinician's manual for neurostimulation systems (available online at medical.abbott/manuals).
For more information about MR Conditional products, visit the Abbott Medical product information page at neuromodulation.abbott/us/en/healthcare-professionals/mri-support.html.
Warnings
The following warnings apply to this neurostimulation system.
Poor surgical risks. Neurostimulation should not be used on patients who are poor surgical risks or patients with multiple illnesses or active general infections.
Magnetic resonance imaging (MRI). Some patients may be implanted with the components that make up a Magnetic Resonance (MR) Conditional system, which allows them to receive an MRI scan if all the requirements for the implanted components and for scanning are met. A physician can help determine if a patient is eligible to receive an MRI scan by following the requirements provided by Abbott Medical. Physicians should also discuss any risks of MRI with patients.
Patients without an MR Conditional neurostimulation system should not be subjected to MRI because the electromagnetic field generated by an MRI may damage the device electronics and induce voltage through the lead that could jolt or shock the patient.
Diathermy therapy. Do not use short-wave diathermy, microwave diathermy, or therapeutic ultrasound diathermy (all now referred to as diathermy) on patients implanted with a neurostimulation system. Energy from diathermy can be transferred through the implanted system and cause tissue damage at the location of the implanted electrodes, resulting in severe injury or death.
Diathermy is further prohibited because it may also damage the neurostimulation system components. This damage could result in loss of therapy, requiring additional surgery for system implantation and replacement. Injury or damage can occur during diathermy treatment whether the neurostimulation system is turned on or off.
Electrosurgery. To avoid harming the patient or damaging the neurostimulation system, do not use monopolar electrosurgery devices on patients with implanted neurostimulation systems. Before using an electrosurgery device, place the device in Surgery Mode using the patient controller app or clinician programmer app. Confirm the neurostimulation system is functioning correctly after the procedure.
Use bipolar electrosurgery only.
Complete any electrosurgery procedures before connecting the leads or extensions to the neurostimulator.
Keep the current paths from the electrosurgery device as far from the neurostimulation system as possible.
Set the electrosurgery device to the lowest possible energy setting.
Confirm that the neurostimulation system is functioning correctly during the implant procedure and before closing the neurostimulator pocket.
Implanted cardiac systems. Physicians need to be aware of the risk and possible interaction between a neurostimulation system and an implanted cardiac system, such as a pacemaker or defibrillator. Electrical pulses from a neurostimulation system may interact with the sensing operation of an implanted cardiac system, causing the cardiac system to respond inappropriately. To minimize or prevent the implanted cardiac system from sensing the output of the neurostimulation system, (1) maximize the distance between the implanted systems; (2) verify that the neurostimulation system is not interfering with the functions of the implanted cardiac system; and (3) avoid programming either device in a unipolar mode (using the device’s can as an anode) or using neurostimulation system settings that interfere with the function of the implantable cardiac system.
Other active implanted devices. The neurostimulation system may interfere with the normal operation of another active implanted device, such as a pacemaker, defibrillator, or another type of neurostimulator. Conversely, the other active implanted device may interfere with the operation of the neurostimulation system.
Interference with other devices. Some of this system’s electronic equipment, such as the programmer and controller, can radiate radiofrequency (RF) energy that may interfere with other electronic devices, including other active implanted devices. Avoid placing equipment components directly over other electronic devices. To correct the effect of interference with other devices, turn off the equipment or increase the distance between the equipment and the device being affected.
Operation of machines, equipment, and vehicles. Patients using therapy that generates paresthesia should turn off stimulation before operating motorized vehicles, such as automobiles, or potentially dangerous machinery and equipment because sudden stimulation changes may distract them from properly operating it. However, current data shows that most patients using BurstDR™ stimulation therapy do not experience paresthesia. For patients who do not feel paresthesia, sudden stimulation changes are less likely to occur and distract them while operating motorized vehicles, machinery, or equipment.
Explosive and flammable gasses. Do not use a clinician programmer or patient controller in an environment where explosive or flammable gas fumes or vapors are present. The operation of these devices could cause them to ignite, causing severe burns, injury, or death.
Keep the device dry. Programmer and controller devices are not waterproof. Keep them dry to avoid damage. Advise patients to not use their device when engaging in activities that might cause it to get wet, such as swimming or bathing.
Pediatric use. Safety and effectiveness of neurostimulation for pediatric use have not been established.
Pregnancy and nursing. Safety and effectiveness of neurostimulation for use during pregnancy and nursing have not been established.
Use in patients with diabetes. Surgical complications and adverse effects may be more frequent and severe in patients with diabetes. The following additional considerations should be made for patients with diabetes:
Stimulation modes. The BurstDR™ stimulation mode has not been evaluated for effectiveness in the diabetic peripheral neuropathy (DPN) population.
Device components. The use of components not approved for use by Abbott Medical with this system may result in damage to the system and increased risk to the patient.
Device modification. Equipment is not serviceable by the customer. To prevent injury or damage to the system, do not modify the equipment. If needed, return the equipment to Abbott Medical for service.
Application modification. To prevent unintended stimulation, do not modify the operating system in any way. Do not use the application if the operating system is compromised (that is, jailbroken).
Case damage. Do not handle the IPG if the case is pierced or ruptured because severe burns could result from exposure to battery chemicals.
IPG disposal. Return all explanted IPGs to Abbott Medical for safe disposal. IPGs contain batteries as well as other potentially hazardous materials. Do not crush, puncture, or burn the IPG because explosion or fire may result.
Product materials. Neurostimulation systems have materials that come in contact or may come in contact with tissue. A physician should determine whether or not a patient may have an allergic reaction to these materials before the system is implanted.
Precautions
The following precautions apply to this neurostimulation system.
Clinician training. Implanting physicians should be experienced in the diagnosis and treatment of chronic pain syndromes and have undergone surgical and device implantation training.
Patient selection. It is extremely important to select patients appropriately for neurostimulation. Thorough psychiatric screening should be performed. Patients should not be dependent on drugs and should be able to operate the neurostimulation system.
Infection. Follow proper infection control procedures. Infections related to system implantation might require that the device be explanted.
Implantation of two systems. If two systems are implanted, ensure that at least 20 cm (8 in.) separates the implanted IPGs to minimize unintended interaction with other system components.
High stimulation outputs. Stimulation at high outputs may cause unpleasant sensations or motor disturbances, or render the patient incapable of controlling the stimulator. If unpleasant sensations occur, the device should be turned off immediately.
Patient training. Instruct patients to use their neurostimulation system only after an authorized clinician has programmed the device and has trained the patient how to control stimulation and safely use the system.
Programmer use. Allow only authorized use of the clinician programmer to avoid any programming changes that may injure a patient.
Single-use, sterile device. The implanted components of this neurostimulation system are intended for a single use only. Sterile components in this kit have been sterilized using ethylene oxide (EtO) gas before shipment and are supplied in sterile packaging to permit direct introduction into the sterile field. Do not resterilize or reimplant an explanted system for any reason.
Storage environment. Store components and their packaging where they will not come in contact with liquids of any kind.
Handle the device with care. The clinician programmer and patient controller are sensitive electronic devices that can be damaged by rough handling, such as dropping them on the ground.
Care and handling of components. Use extreme care when handling system components prior to implantation. Excessive heat, excessive traction, excessive bending, excessive twisting, or the use of sharp instruments may damage and cause failure of the components.
Package or component damage. Do not implant a device if the sterile package or components show signs of damage, if the sterile seal is ruptured, or if contamination is suspected for any reason. Return any suspect components to Abbott Medical for evaluation.
Exposure to body fluids or saline. Prior to connection, exposure of the metal contacts, such as those on the connection end of a lead or extension, to body fluids or saline can lead to corrosion. If such exposure occurs, clean the affected parts with sterile, deionized water or sterile water for irrigation, and dry them completely prior to lead connection and implantation.
System testing. To ensure correct operation, always test the system during the implant procedure, before closing the neurostimulator pocket, and before the patient leaves the surgery suite.
High-output ultrasonics and lithotripsy. The use of high-output devices, such as an electrohydraulic lithotripter, may cause damage to the electronic circuitry of an implanted IPG. If lithotripsy must be used, do not focus the energy near the IPG.
Ultrasonic scanning equipment. The use of ultrasonic scanning equipment may cause mechanical damage to an implanted neurostimulation system if used directly over the implanted system.
External defibrillators. The safety of discharge of an external defibrillator on patients with implanted neurostimulation systems has not been established.
Therapeutic radiation. Therapeutic radiation may damage the electronic circuitry of an implanted neurostimulation system, although no testing has been done and no definite information on radiation effects is available. Sources of therapeutic radiation include therapeutic X-rays, cobalt machines, and linear accelerators. If radiation therapy is required, the area over the implanted IPG should be shielded with lead. Damage to the system may not be immediately detectable.
Security, antitheft, and radiofrequency identification (RFID) devices. Some antitheft devices, such as those used at entrances or exits of department stores, libraries, and other public places, and airport security screening devices may affect stimulation. Additionally, RFID devices, which are often used to read identification badges, as well as some tag deactivation devices, such as those used at payment counters at stores and loan desks at libraries, may also affect stimulation.
Patients who are implanted with nonadjacent multiple leads and patients who are sensitive to low stimulation thresholds may experience a momentary increase in their perceived stimulation, which some patients have described as uncomfortable or jolting. Patients should cautiously approach such devices and should request help to bypass them. If they must go through a gate or doorway containing this type of device, patients should turn off their IPG and proceed with caution, being sure to move through the device quickly.
Scuba diving or hyperbaric chambers. Patients should not dive below 30 m (100 ft.) of water or enter hyperbaric chambers above 4.0 atmospheres absolute (ATA). Pressures below 30 m (100 ft.) of water (or above 4.0 ATA) could damage the neurostimulation system. Before diving or using a hyperbaric chamber, patients should discuss the effects of high pressure with their physician.
Wireless use restrictions. In some environments, the use of wireless functions (for example, Bluetooth® wireless technology) may be restricted. Such restrictions may apply aboard airplanes, in hospitals, near explosives, or in hazardous locations. If you are unsure of the policy that applies to the use of this device, please ask for authorization to use it before turning it on. (Bluetooth® is a registered trademark of Bluetooth SIG, Inc.)
Adverse Effects
In addition to those risks commonly associated with surgery, the following risks are associated with implanting or using this neurostimulation system:
Unpleasant sensations or motor disturbances, including involuntary movement, caused by stimulation at high outputs; if either occurs, turn off your IPG immediately
Undesirable changes in stimulation, which may be related to cellular changes in tissue around the electrodes, changes in electrode position, loose electrical connections, or lead failure
Stimulation in unwanted places (such as radicular stimulation of the chest wall)
Lead migration, causing changes in stimulation or reduced pain relief
Epidural hemorrhage, hematoma, infection, spinal cord compression, or paralysis from placement of a lead in the epidural space
Cerebrospinal fluid (CSF) leakage
Paralysis, weakness, clumsiness, numbness, or pain below the level of the implant
Persistent pain at the electrode or IPG site
Seroma (mass or swelling) at the IPG site
Allergic or rejection response to implant materials

Intended Use
This neurostimulation system is designed to deliver low-intensity electrical impulses to nerve structures. The system is intended to be used with leads and associated extensions that are compatible with the system.
Indications For Use
This neurostimulation system is indicated for spinal column stimulation via epidural and intraspinal lead access to the dorsal root ganglion as an aid in the management of moderate to severe chronic intractable* pain of the lower limbs in adult patients with complex regional pain syndrome (CRPS) types I and II.**
*Study subjects from the ACCURATE clinical study had failed to achieve adequate pain relief from at least two prior pharmacologic treatments from at least two different drug classes and continued their pharmacologic therapy during the clinical study.
**Please note that in 1994, a consensus group of pain medicine experts gathered by the International Association for the Study of Pain (IASP) reviewed diagnostic criteria and agreed to rename reflex sympathetic dystrophy (RSD) and causalgia as complex regional pain syndrome (CRPS) types I and II, respectively. CRPS II (causalgia) is defined as a painful condition arising from damage to a nerve. Nerve damage may result from traumatic or surgical nerve injury. Changes secondary to neuropathic pain seen in CRPS I (RSD) may be present, but are not a diagnostic requirement for CRPS II (causalgia).

Warnings
The following warnings apply to this neurostimulation system.
Clinician training. Implanting physicians should be experienced in the diagnosis and treatment of chronic pain syndromes and have undergone surgical and device implantation training for dorsal root ganglion (DRG) neurostimulation systems.
Pregnancy and nursing. Safety and effectiveness of neurostimulation for use during pregnancy and nursing have not been established.
Pediatric use. The safety and effectiveness of neurostimulation for pediatric use have not been established.
Back pain. The safety and efficacy for the treatment of patients who have back pain as the greatest region of pain have not been evaluated.
External defibrillators. Safety for use of external defibrillator discharges on a patient receiving neurostimulation has not been established. External defibrillation can cause induced currents in the lead-extension portion of the neurostimulation system. After defibrillation, confirm the neurostimulation system is still working.
Magnetic resonance imaging (MRI). Some patients may be implanted with the components that make up a Magnetic Resonance (MR) Conditional system, which allows them to receive an MRI scan if all the requirements for the implanted components and for scanning are met. A physician can help determine if a patient is eligible to receive an MRI scan by following the requirements provided by Abbott Medical. Physicians should also discuss any risks of MRI with patients.
Patients without an MR Conditional neurostimulation system should not be subjected to MRI because the electromagnetic field generated by an MRI may damage the device electronics, cause heating at the lead tip that could result in tissue damage, and induce voltage through the lead that could jolt or shock the patient.
Computed tomography (CT). If the patient requires a CT scan, all stimulation should be turned off before the procedure. If stimulation is not turned off, the patient may experience a momentary increase in stimulation, which may be uncomfortable. Before beginning a CT scan, the operator should use CT scout views to determine if implanted or externally worn electronic medical devices are present and if so, their location relative to the programmed scan range.
For CT procedures in which the medical device is in or immediately adjacent to the programmed scan range, the operator should:
Determine the device type
If practical, try to move external devices out of the scan range
Ask patients with neurostimulators to shut off the device temporarily while the scan is performed.
Minimize X-ray exposure to the implanted or externally worn electronic medical device by using the lowest possible X-ray tube current consistent with obtaining the required image quality and by making sure that the X-ray beam does not dwell over the device for more than a few seconds.
Important note: For CT procedures that require scanning over the medical device continuously for more than a few seconds, as with CT perfusion or interventional exams, attending staff should be ready to take emergency measures to treat adverse reactions if they occur.
After CT scanning directly over the implanted or externally worn electronic medical device:
Have the patient turn the device back on if it had been turned off prior to scanning.
Have the patient check the device for proper functioning, even if the device was turned off.
Advise patients to contact their healthcare provider as soon as possible if they suspect their device is not functioning properly after a CT scan.
Diathermy therapy. Do not use short-wave diathermy, microwave diathermy, or therapeutic ultrasound diathermy (all now referred to as diathermy) on patients implanted with a neurostimulation system. Energy from diathermy can be transferred through the implanted system and cause tissue damage at the location of the implanted electrodes, resulting in severe injury or death.
Diathermy is further prohibited because it may also damage the neurostimulation system components. This damage could result in loss of therapy, requiring additional surgery for system implantation and replacement. Injury or damage can occur during diathermy treatment whether the neurostimulation system is turned on or off. Advise patients to inform their healthcare professional that they should not be exposed to diathermy treatment.
Electrosurgery. To avoid harming the patient or damaging the neurostimulation system, do not use monopolar electrosurgery devices on patients with implanted neurostimulation systems. Before using an electrosurgery device, place the device in Surgery Mode using the patient controller app or clinician programmer app. Confirm the neurostimulation system is functioning correctly after the procedure.
During implant procedures, if electrosurgery devices must be used, take the following actions:
Use bipolar electrosurgery only.
Complete any electrosurgery procedures before connecting the leads or extensions to the neurostimulator.
Keep the current paths from the electrosurgery device as far from the neurostimulation system as possible.
Set the electrosurgery device to the lowest possible energy setting.
Confirm that the neurostimulation system is functioning correctly during the implant procedure and before closing the neurostimulator pocket.
Implanted cardiac systems. Physicians need to be aware of the risk and possible interaction between a neurostimulation system and an implanted cardiac system, such as a pacemaker or defibrillator. Electrical pulses from a neurostimulation system may interact with the sensing operation of an implanted cardiac system, causing the cardiac system to respond inappropriately. To minimize or prevent the implanted cardiac system from sensing the output of the neurostimulation system:
Maximize the distance between the implanted systems;
Verify that the neurostimulation system is not interfering with the functions of the implanted cardiac system; and
Avoid programming either device in a unipolar mode (using the device’s can as an anode) or using neurostimulation system settings that interfere with the function of the implantable cardiac system
Other active implantable devices. The effect of other implanted devices, including deep brain stimulators, peripheral nerve stimulators, implanted drug delivery pumps, and cochlear implants on the neurostimulation system are unknown.
Radiofrequency or microwave ablation. Safety has not been established for radiofrequency (RF) or microwave ablation in patients who have an implanted neurostimulation system. Induced electrical currents may cause heating, especially at the lead electrode site, resulting in tissue damage.
Emergency procedures. Instruct patients to designate a representative (family member or close friend) to notify any emergency medical personnel of their implanted neurostimulation system if emergency care is required. Patients will receive an identification card to carry with them that will inform emergency medical personnel of their implanted system. Advise patients to use caution when undergoing any procedure that could include radiofrequency (RF) or microwave ablation, defibrillation, or cardioversion.
Ultrasonic scanning equipment. The use of ultrasonic scanning equipment may cause mechanical damage to an implanted neurostimulation system if used directly over the implanted system.
Therapeutic radiation. Therapeutic radiation may damage the electronic circuitry of an implanted neurostimulation system, although no testing has been done and no definite information on radiation effects is available. Sources of therapeutic radiation include therapeutic X rays, cobalt machines, and linear accelerators. If radiation therapy is required, the area over the implanted IPG should be shielded with lead. Damage to the system may not be immediately detectable.
Restricted areas. Warn patients to seek medical guidance before entering environments that could adversely affect the operation of the implanted device, including areas protected by a warning notice preventing entry by patients fitted with a pacemaker.
Component manipulation by patients. The patient must be instructed to not rub or exert pressure on implanted components through the skin as this may cause lead dislodgement leading to stimulation at the implant site, IPG inversion leading to the inability to communicate with the device, or skin erosion that can lead to another surgical procedure or possible infection.
Implantation at vertebral levels above T10. The safety and efficacy of implantation of leads implanted above the T10 vertebral level have not been evaluated.
Number of leads implanted. The safety and efficacy of the implantation of greater than four leads have not been evaluated.
Lead movement. Patients should be instructed to avoid bending, twisting, stretching, and lifting objects over 2 kg (5 lb) for at least six weeks after implantation. These activities may cause lead movement, resulting in under stimulation or overstimulation for the patient. Excessive lead migration may require reoperation to replace the leads.
Scuba diving and hyperbaric chambers. Instruct patients to avoid scuba diving and entering hyperbaric chambers above 1.5 atmospheres absolute (ATA) because these activities might damage the neurostimulation system.
Operation of machines, equipment, and vehicles. In the clinical experience with this device, patients have experienced few effects when moving from lying down to sitting up. Therefore, it is unlikely patients will need to adjust stimulation when changing positions or moving.
However, advise patients who feel uncomfortable paresthesia during postural changes that they should not operate potentially dangerous equipment such as power tools, automobiles, or other motor vehicles. These patients should not climb ladders or participate in activities where postural changes or abrupt movements could alter the perception of stimulation intensity and cause patients to fall or lose control of equipment or vehicles or injure others.
Explosive and flammable gasses. Do not use a clinician programmer or patient controller in an environment where explosive or flammable gas fumes or vapors are present. The operation of these devices could cause them to ignite, causing severe burns, injury, or death.
Keep the device dry. Programmer and controller devices are not waterproof. Keep them dry to avoid damage. Advise patients to not use their device when engaging in activities that might cause it to get wet, such as swimming or bathing.
Device components. The use of components not approved for use by Abbott Medical with this system may result in damage to the system and increased risk to the patient.
Device modification. The equipment is not serviceable by the customer. To prevent injury or damage to the system, do not modify the equipment. If needed, return the equipment to Abbott Medical for service.
Application modification. To prevent unintended stimulation, do not modify the operating system in any way. Do not use the application if the operating system is compromised (i.e., jailbroken).
Case damage. Do not handle the IPG if the case is pierced or ruptured because severe burns could result from exposure to battery chemicals.
Cremation. The IPG should be explanted before cremation because the IPG could explode. Return the explanted IPG to Abbott Medical.
IPG disposal. Return all explanted IPGs to Abbott Medical for safe disposal. IPGs contain batteries as well as other potentially hazardous materials. Do not crush, puncture, or burn the IPG because explosion or fire may result.
Product materials. Neurostimulation systems have materials that come in contact or may come in contact with tissue. A physician should determine whether or not a patient may have an allergic reaction to these materials before the system is implanted.
Additional Warnings for Leads
Conscious sedation. The placement of the leads involves some risk, as with any surgical procedure. Conscious sedation can cause side effects such as systemic toxicity, or cardiovascular or pulmonary problems. Use caution when sedating the patient. The patient must be awake and conversant during the procedure to minimize the likelihood of nerve damage.
Preventing infection. Always remove the trial leads before implanting the implant leads to avoid the risk of infection that may cause death if the leads are not removed. Use appropriate sterile technique when implanting leads and the IPG.
Lead damage from tools. Use extreme care when using sharp instruments or electrosurgery devices around the lead to avoid damaging the lead.
Needle positioning. Always be aware of the needle tip position. Use caution when positioning the needle to avoid unintended injury to surrounding anatomical structures.
Needle insertion. When using a contralateral approach, advance the needle slowly into the epidural space and take caution as it enters. The needle will be inserted at a steeper angle than in an antegrade approach and there is a greater chance of dural puncture that will lead to a cerebrospinal fluid leak.
Advancing components. Use fluoroscopy and extreme care when inserting, advancing, or manipulating the guidewire or lead in the epidural space to minimize the risk of a dural tear. Dural puncture can occur if needle or guidewire is advanced aggressively once loss of resistance is achieved. Advance the needle and guidewire slowly. Do not use excessive force to push the lead or sheath into the neural foramen as this may result in permanent or transient nerve damage.
Removing components. Use extreme care when removing the lead stylet, the delivery sheath, and the needle to ensure that the distal tip of the lead remains in the desired location. Removing each item in slow movements while holding the remaining components in place will assist this process.
Sheath insertion warning. Insertion of a sheath without the lead may result in dural puncture. Securing the lead with the lead stabilizer will mitigate this risk.
Sheath retraction. If the sheath needs to be retracted from the epidural space, verify that the steering wing is rotated away from the needle mark no more than 90 degrees. Failure to do so may result in damage to the sheath. Before reinserting the sheath, verify there is no damage to the sheath.
Sheath rotation. If the sheath is not responding to rotation, do not rotate the steering wing out of plane from the curve of the sheath more than 90 degrees. The tip of the sheath may whip around and could cause harm to the patient.
Lead insertion through sheath. If the lead is unable to deploy out of the sheath, inject sterile water or saline slowly to release tissue that may have entered between the sheath and the lead. Do not use excessive pressure when injecting through the sheath.
Removing a kinked sheath. If the sheath has been kinked during delivery, slowly retract through the needle with the curve facing the same direction as the bevel. Failure to do so can damage or cut the lead or sheath. If resistance is encountered, pull the needle out of the epidural space and then remove the sheath.
Providing strain relief. Failure to provide strain relief may result in lead migration requiring a revision procedure.
Anchoring leads. Do not suture directly onto the lead to avoid damaging the lead. Failure to appropriately anchor the lead may cause lead migration, motor activation, or painful stimulation.
Remove leads slowly. Remove leads slowly (at a suggested rate of 1 cm/s while holding the lead between the thumb and forefinger) to avoid breaking the lead and leaving fragments in the patient. If resistance is met while removing leads from the epidural space, do not use excessive force to extract. Always perform removal with the patient conscious and able to give feedback.
Precautions
The following precautions apply to this neurostimulation system.
Patient selection. It is extremely important to select patients appropriately for neurostimulation. Thorough psychiatric screening should be performed. Patients should not be dependent on drugs and should be able to operate the neurostimulation system.
Infection. Follow proper infection control procedures. Infections related to system implantation might require that the device be explanted.
Implantation of multiple leads. If multiple leads or extensions are implanted, the leads and extensions should be routed in close proximity. Nonadjacent leads and extensions have the possibility of creating a conduit for stray electromagnetic energy that could cause the patient unwanted stimulation.
High stimulation outputs. Stimulation at high outputs may cause unpleasant sensations or motor disturbances, or render the patient incapable of controlling the stimulator. If unpleasant sensations occur, the device should be turned off immediately.
Postural changes. In the clinical experience with this device, patients have experienced few effects when moving from lying down to sitting up. Therefore, it is unlikely patients will need to adjust stimulation when changing positions or moving. However, some patients may experience a decrease or increase in the perceived level of stimulation. Perception of higher levels of stimulation has been described by some patients as uncomfortable, painful, or jolting.
Advise patients who experience these types of stimulation changes to turn down the amplitude or turn off the IPG before making extreme posture changes or abrupt movements such as stretching, lifting their arms over their heads, or exercising. If unpleasant sensations occur, the IPG should be turned off immediately.
Advise patients about adverse effects. Instruct patients to contact their physician if they experience any adverse effects, such as unusual pain or discomfort during stimulation and swelling, redness, tenderness, or pain around implanted components.
Patient training. Instruct patients to use their neurostimulation system only after an authorized clinician has programmed the device and has trained the patient how to control stimulation and safely use the system.
Programmer use. Allow only authorized use of the clinician programmer to avoid any programming changes that may injure a patient.
Battery precaution. The clinician programmer and patient controller contain a battery and other potentially hazardous materials. Do not crush, puncture, or burn these devices because explosion or fire may result. Return them to Abbott Medical for proper disposal.
Stimulation effectiveness. The long-term effectiveness of dorsal root ganglion (DRG) stimulation has not been documented, and not all patients realize the long-term benefits from DRG stimulation. Stimulation effectiveness has been established for one year.
Single-use, sterile device. The implanted components of this neurostimulation system are intended for a single use only. Sterile components in this kit have been sterilized using ethylene oxide (EtO) gas before shipment and are supplied in sterile packaging to permit direct introduction into the sterile field. Do not resterilize or reimplant an explanted system for any reason.
Storage environment. Store components and their packaging where they will not come in contact with liquids of any kind.
Expiration date. An expiration date (or “use-before” date) is printed on the packaging. Do not use the system if the use-before date has expired.
Package or component damage. Before opening any sterile package, verify the kit model number, that the kit is within its expiration (use-before) date, and that the packaging has not been damaged or compromised in any way. If the packaging has been compromised, the device is beyond its expiration date, or the sterile package or device show signs of damage, do not use the device as it may be compromised and could cause harm to the patient. Return any suspect components to Abbott Medical for evaluation.
Handle the device with care. The clinician programmer and patient controller are sensitive electronic devices that can be damaged by rough handling, such as dropping them on the ground.
Lead inspection. Carefully inspect the lead (in the sterile field) for damage after removing it from the sterile package. Damage to the lead body can cause improper function and stimulation or stimulation to areas other than the intended target.
Care and handling of components. Use extreme care when handling system components prior to implantation. Excessive heat, excessive traction, excessive bending, excessive twisting, or the use of sharp instruments may damage and cause failure of the components.
Component handling. Do not bend, kink, or stretch the lead body, sheaths, or other components as this may result in damage to the component and poor function.
Using surgical instruments. Do not use surgical instruments to handle the lead. The force of the instruments may damage the lead or stylet.
Using the tunneling tool. Use extreme care to not damage the lead with the sharp point of the tunneling tool.
Component manipulation. Do not over-manipulate the sheath and lead system as this may result in trauma within the epidural space.
Stylet handling. Do not bend, kink, or use surgical instruments on the stylet, as this may damage it. Use care when reinserting a stylet. Too much pressure on the stylet could damage the lead, resulting in intermittent or loss of stimulation. Remove the stylet from the lead only when satisfied with lead placement. If the stylet is removed from the lead, it may be difficult to reinsert it.
Sheath insertion precaution. Do not insert the sheath into the epidural space without the lead or guidewire inserted, as this may cause injury to the dura.
Stabilizing the lead during insertion. When inserting the lead-sheath assembly through the needle into the epidural space, tighten the lead stabilizer to prevent lead migration out of the sheath. Failure to do so may cause harm to the patient such as damage to the dura.
Bending the sheath. Do not bend the sheath without the lead inside the sheath, as this will permanently kink it and make it difficult to deploy the lead.
Lead handling. If the operating field is bloody, wipe gloves, lead, stylet, and sheath before handling the lead. Failure to do so may result in difficulty delivering the lead.
Exposure to body fluids or saline. Prior to connection, exposure of the metal contacts, such as those on the connection end of a lead or extension, to body fluids or saline can lead to corrosion. If such exposure occurs, clean the affected parts with sterile, deionized water or sterile water for irrigation, and dry them completely prior to lead connection and implantation.
Inserting the anchor. Failure to push the short end of the soft tissue anchor into the ligament or fascia may result in lead migration and a procedure to revise the lead location.
Securing the anchor. Use caution when securing the soft tissue anchor because damage to the anchor or lead can occur and result in failure of the system.
Placing the IPG. Do not place the IPG deeper than 4.0 cm (1.57 in) because the clinician programmer or patient controller may not communicate effectively with the IPG.
Securing the IPG. Do not bring the suture needle in contact with an IPG, lead, or extension, or the component may be damaged.
System testing. To ensure correct operation, always test the system during the implant procedure, before closing the neurostimulator pocket, and before the patient leaves the surgery suite.
Conscious sedation during removal. Always perform removal of implanted components with the patient conscious and able to give feedback.
Surgical advice for removal. If resistance is met while removing leads from the epidural space, do not use excessive force to extract. Consider seeking surgical advice if you cannot easily remove a lead.
Component disposal. Return all explanted components to Abbott Medical for safe disposal.
High-output ultrasonics and lithotripsy. The use of high-output devices, such as an electrohydraulic lithotriptor, may cause damage to the electronic circuitry of an implanted IPG. If lithotripsy must be used, do not focus the energy near the IPG.
Transcranial magnetic stimulation (TMS) and electroconvulsive therapy (ECT). Safety has not been established for TMS or ECT in patients who have an implanted neurostimulation system. Induced electrical currents may cause heating, especially at the lead electrode site, resulting in tissue damage.
Transcutaneous electrical nerve stimulation (TENS). Do not place TENS electrodes so that the TENS current passes over any part of the neurostimulation system. If patients feel that the TENS device may be interfering with the neurostimulator, patients should discontinue using the TENS device until they talk with their physician.
Electromagnetic interference (EMI). Some equipment in home, work, medical, and public environments can generate EMI that is strong enough to interfere with the operation of a neurostimulation system or damage system components. Patients should avoid getting too close to these types of EMI sources, which include the following examples:
commercial electrical equipment (such as arc welders and induction furnaces)
communication equipment (such as microwave transmitters and high-power amateur transmitters)
high-voltage power lines
radiofrequency identification (RFID) devices
some medical procedures (such as therapeutic radiation, static magnetic field [SMF] therapy, and electromagnetic lithotripsy)
and some medical devices (such as bone growth stimulators, transcutaneous electrical nerve stimulation [TENS] devices, dental drills, and ultrasonic probes)
Interference with wireless equipment. Wireless communications equipment, such as mobile and cordless phones and walkie-talkies, may interfere with the IPG if the equipment gets too close to the IPG. To correct the effects of typical interference, keep wireless communication equipment at least 15 cm (6 in) from the IPG.
Wireless use restrictions. In some environments, the use of wireless functions (e.g., Bluetooth® wireless technology) may be restricted. Such restrictions may apply aboard airplanes, in hospitals, near explosives, or in hazardous locations. If you are unsure of the policy that applies to the use of this device, please ask for authorization to use it before turning it on. (Bluetooth® is a registered trademark of Bluetooth SIG, Inc.)
Security, antitheft, and radiofrequency identification (RFID) devices. Some antitheft devices, such as those used at entrances or exits of department stores, libraries, and other public places, and airport security screening devices may affect stimulation.
Additionally, RFID devices, which are often used to read identification badges, as well as some tag deactivation devices, such as those used at payment counters at stores and loan desks at libraries, may also affect stimulation.
Patients who are implanted with nonadjacent multiple leads and patients who are sensitive to low stimulation thresholds may experience a momentary increase in their perceived stimulation, which some patients have described as uncomfortable or jolting. Patients should cautiously approach such devices and should request help to bypass them. If they must go through a gate or doorway containing this type of device, patients should turn off their IPG and proceed with caution, being sure to move through the device quickly.
Overcommunicating with the IPG. Advise patients to use their patient controller to communicate with their IPG only when needed because excessive communication with the IPG can shorten the remaining battery life.
Mobile phones. While interference with mobile phones is not anticipated, technology continues to change and interaction between a neurostimulation system and a mobile phone is possible. Advise patients to contact their physician if they are concerned about their mobile phone interacting with their neurostimulation system.
Adverse Effects
In addition to those risks commonly associated with surgery, the following risks are associated with using this neurostimulation system:
Unpleasant sensations or motor disturbances, including involuntary movement, caused by stimulation at high outputs (if either occurs, turn off your IPG immediately.)
Undesirable changes in stimulation, which may be related to cellular changes in tissue around the electrodes, changes in electrode position, loose electrical connections, or lead failure or breakage
Stimulation in unwanted places (such as stimulation of the chest wall)
Lead migration, causing changes in stimulation or reduced pain relief
Epidural hemorrhage, hematoma, infection, spinal cord compression, or paralysis from placement of a lead in the epidural space Cerebrospinal fluid (CSF) leakage
Tissue damage or nerve damage
Paralysis, weakness, clumsiness, numbness, sensory loss, or pain below the level of the implant
Pain or bleeding where the needle was inserted
Persistent pain at the electrode or IPG site
Escalating pain
Seroma (mass or swelling) at the implant site
Headache
Allergic or rejection response to device or implant materials
Implant migration or skin erosion around the implant
Battery failure, leakage, or both
Hardware malfunction that requires replacing the neurostimulator
Pain from a noninjurious stimulus to the skin or an exaggerated sense of pain
Formation of reactive tissue in the epidural space around the lead, which can cause delayed spinal cord compression and paralysis and requires surgical intervention (Time to onset can range 23 from weeks to many years after implant.)
Additional risks to the patients, as a result of the placement and stimulation of the lead in the area of the dorsal root ganglion (DRG), include pain from setting the stimulation parameters too high. This may occur once the lead is in place and is connected to the neurostimulator and activated. The neurostimulator is controlled by a trained operator and the starting point for the stimulation will be set to the lowest available settings. Additionally, all patients will be awake and conversant during the procedure to minimize the impact.

MRI Safety Information
Some models of this system are Magnetic Resonance (MR) Conditional, and patients with these devices may be scanned safely with magnetic resonance imaging (MRI) when the conditions for safe scanning are met. For more information about MR Conditional neurostimulation components and systems, including equipment settings, scanning procedures, and a complete listing of conditionally approved components, refer to the MRI procedures clinician's manual for neurostimulation systems (available online at medical.abbott/manuals). For more information about MR Conditional products, visit the Abbott Medical product information page at neuromodulation.abbott/MRI-ready.
Warnings
The following warnings apply to this neurostimulation system.
Pregnancy and nursing. Safety and effectiveness of neurostimulation for use during pregnancy and nursing have not been established. Patients should not use this neurostimulation system if they are pregnant or nursing.
Magnetic resonance imaging (MRI). Some patients may be implanted with the components that make up a Magnetic Resonance (MR) Conditional system, which allows them to receive an MRI scan if all the requirements for the implanted components and for scanning are met. A physician can help determine if a patient is eligible to receive an MRI scan by following the requirements provided by Abbott Medical. Physicians should also discuss any risks of MRI with patients.
Patients without an MR Conditional neurostimulation system should not be subjected to MRI because the electromagnetic field generated by an MRI may damage the device electronics and induce voltage through the lead that could jolt or shock the patient.
High stimulation outputs and charge density limits. Avoid excessive stimulation. A risk of brain tissue damage exists with parameter settings using high amplitudes and wide pulse widths.
High amplitudes and wide pulse widths should only be programmed with due consideration of the warnings concerning charge densities. The system can be programmed to use parameter settings outside the range of those used in the clinical studies. If the programming of stimulation parameters exceeds the charge density limit of 30 μC/cm2, a screen will appear warning you that the charge density is too high. Charge density can be reduced by lowering the stimulation amplitude or pulse width. For more information, see the clinician programmer manual.
Higher amplitudes and wider pulse widths may indicate a system problem or a suboptimal lead placement. Stimulation at high outputs may cause unpleasant sensations or motor disturbances or may render the patient incapable of controlling the patient controller. If unpleasant sensations occur, the device should be turned off immediately using the patient magnet.
Diathermy therapy. Do not use short-wave diathermy, microwave diathermy, or therapeutic ultrasound diathermy (all now referred to as diathermy) on patients implanted with a neurostimulation system. Energy from diathermy can be transferred through the implanted system and cause tissue damage at the location of the implanted electrodes, resulting in severe injury or death.
Diathermy is further prohibited because it may also damage the neurostimulation system components. This damage could result in loss of therapy, requiring additional surgery for system implantation and replacement. Injury or damage can occur during diathermy treatment whether the neurostimulation system is turned on or off.
Risk of depression, suicidal ideations, and suicide. New onset or worsening depression, which may be temporary or permanent, is a risk that has been reported with DBS therapy. Suicidal ideation, suicide attempts, and suicide are events that have also been reported. Therefore, physicians should consider the following:
Preoperatively, assess patients for the risks of depression and suicide. This assessment should consider both the risk of depression and suicide as well as the potential clinical benefits of DBS therapy for the condition being treated.
Postoperatively, actively monitor patients for new or worsening symptoms of depression, suicidal thoughts or behaviors, or changes in mood or impulse control.
If a patient experiences new or worsening depression or suicidal ideation, manage these symptoms appropriately.
Educate patients and caregivers about these potential risks prior to implantation, and be sure that they know about the importance of ongoing support and follow-up, including when to contact their health care provider.
Poor surgical risks. Neurostimulation should not be used on patients who are poor surgical risks or patients with multiple illnesses or active general infections.
Explosive or flammable gasses. Do not use the clinician programmer or patient controller in an environment where explosive or flammable gas fumes or vapors are present. The operation of the clinician programmer or patient controller could cause them to ignite, causing severe burns, injury, or death.
Operation of machinery and equipment. Patients should not operate potentially dangerous machinery, power tools, or vehicles or engage in any activity that could be unsafe if their symptoms were to unexpectedly return.
Pediatric use. Safety and effectiveness of neurostimulation for pediatric use have not been established.
Device components. The use of components not approved for use by Abbott Medical with this system may result in damage to the system and increased risk to the patient.
Device modification. This equipment is not serviceable by the customer. To prevent injury or damage to the system, do not modify the equipment. If needed, return the equipment to Abbott Medical for service.
Application modification. To prevent unintended stimulation, do not modify the generator software in any way. Only apply software updates that are published directly by Abbott Medical.
Electrosurgery. To avoid harming the patient or damaging the neurostimulation system, do not use monopolar electrosurgery devices on patients with implanted neurostimulation systems. Before using an electrosurgery device, place the device in Surgery Mode using the patient controller app or clinician programmer app. Confirm the neurostimulation system is functioning correctly after the procedure.
During implant procedures, if electrosurgery devices must be used, take the following actions:
Use bipolar electrosurgery only.
Complete any electrosurgery procedures before connecting the leads or extensions to the neurostimulator.
After any surgery, check the neurostimulation system for the following:
Radiofrequency or microwave ablation. Careful consideration should be used before using radiofrequency (RF) or microwave ablation in patients who have an implanted neurostimulation system since safety has not been established. Induced electrical currents may cause heating, especially at the lead electrode site, resulting in tissue damage.
Implanted cardiac systems. Physicians need to be aware of the risk and possible interaction between a neurostimulation system and an implanted cardiac system, such as a pacemaker or defibrillator. Electrical pulses from a neurostimulation system may interact with the sensing operation of an implanted cardiac system, causing the cardiac system to respond inappropriately. To minimize or prevent the implanted cardiac system from sensing the output of the neurostimulation system:
Maximize the distance between the implanted systems;
Verify that the neurostimulation system is not interfering with the functions of the implanted cardiac system; and
Avoid programming either device in a unipolar mode (using the device’s can as an anode) or using neurostimulation system settings that interfere with the function of the implantable cardiac system.
Other active implanted devices. The neurostimulation system may interfere with the normal operation of another active implanted device, such as a pacemaker, defibrillator, or another type of neurostimulator. Conversely, the other active implanted device may interfere with the operation of the neurostimulation system.
Interference with other devices. Some of this system’s electronic equipment, such as the programmer and controller, can radiate radiofrequency (RF) energy that may interfere with other electronic devices, including other active implanted devices. Avoid placing equipment components directly over other electronic devices. To correct the effect of interference with other devices, turn off the equipment or increase the distance between the equipment and the device being affected.
Case damage. If the case of the implantable pulse generator (IPG) is pierced or ruptured, severe burns could result from exposure to battery chemicals.
Cremation. The IPG should be explanted before cremation because the IPG could explode. Return the explanted IPG to Abbott Medical.
Generator disposal. Return all explanted components to Abbott Medical for safe disposal. IPGs contain batteries as well as other potentially hazardous materials. Do not crush, puncture, or burn the IPG because explosion or fire may result.
Product materials. Neurostimulation systems have materials that come in contact or may come in contact with tissue. A physician should determine whether or not a patient may have an allergic reaction to these materials before the system is implanted.
Coagulopathies. Physicians should use extreme care with lead implantation in patients with a heightened risk of intracranial hemorrhage. Physicians should also consider underlying factors, such as previous neurological injury or prescribed medications (anticoagulants), that may predispose a patient to the risk of bleeding.
Low frequencies. Stimulation frequencies at less than 30 Hz may cause tremor to be driven (meaning that tremor occurs at the same frequency as the programmed frequency). For this reason, programming at frequencies less than 30 Hz is not recommended.
Return of symptoms and rebound effect. The abrupt cessation of stimulation for any reason will probably cause disease symptoms to return. In some cases, symptoms may return with a greater intensity than what a patient experienced before system implantation (rebound effect). In rare cases, this can create a medical emergency.
Precautions
The following precautions apply to this neurostimulation system.
General Precautions
Surgeon training. Implanting physicians should be experienced in stereotactic and functional neurosurgery.
Clinician training. Clinicians should be familiar with deep brain stimulation therapy and be experienced in the diagnosis and treatment of the indication for which the deep brain stimulation components are being used.
Patient training. Instruct patients to use their neurostimulation system only after an authorized clinician has programmed the generator and has trained the patient on how to safely control stimulation and to charge the system
Patient selection. Select patients appropriately for deep brain stimulation. The patient should be able and willing to use the patient controller and correctly interpret the icons and messages that appear on the screen.
Especially consider the following additional factors when selecting patients:
Level of available support from a caregiver.
Expected effect from cessation of therapy, should disease symptoms return unexpectedly.
Patient's age, as very young or very old patients may have difficulty performing required monitoring of the device.
Patient's mental capacity, as patients with cognitive impairment or those prone to developing dementia would likely have difficulty performing device-related tasks without assistance.
Patient's physical ability, as patients with higher degrees of motor impairment might have difficulty with the physical requirements of monitoring the device.
Patient's visual ability to read the patient controller screen.
Infection. Follow proper infection control procedures. Infections may require that the device be explanted.
Implantation of two systems. If two systems are implanted, ensure that at least 20 cm (8 in.) separates the implanted generators to minimize unintended interaction with other system components.
Implantation of multiple leads. If multiple leads are implanted, leads and extensions should be routed in close proximity. Nonadjacent leads can possibly create a conduit for stray electromagnetic energy that could cause the patient unwanted stimulation.
Implant heating. While charging the generator, patients may perceive an increase in temperature at the generator site. In patients who have areas of increased sensitivity to heat, consider placing the implant where the patient has normal sensation.
Electromagnetic interference (EMI). Some equipment in home, work, medical, and public environments can generate EMI that is strong enough to interfere with the operation of a neurostimulation system or damage system components. Patients should avoid getting too close to these types of EMI sources, which include the following examples:
Commercial electrical equipment (such as arc welders and induction furnaces),
Communication equipment (such as microwave transmitters and high-power amateur transmitters),
High-voltage power lines,
Radiofrequency identification (RFID) devices,
And some medical procedures (such as therapeutic radiation and electromagnetic lithotripsy).
Programmer use. Allow only authorized use of the clinician programmer to avoid any programming changes that may injure a patient.
Security, antitheft, and radiofrequency identification (RFID) devices. Some antitheft devices, such as those used at entrances or exits of department stores, libraries, and other public places, and airport security screening devices may affect stimulation. Additionally, RFID devices, which are often used to read identification badges, as well as some tag deactivation devices, such as those used at payment counters at stores and loan desks at libraries, may also affect stimulation.
Patients should cautiously approach such devices and should request help to bypass them. If they must go through or near a gate or doorway containing this type of device, patients should move quickly and then check their IPG to determine if it is turned on or off.
Unauthorized changes to stimulation parameters. Caution patients to not make unauthorized changes to physician-established stimulation parameters.
Damage to shallow implants. Falling and other traumatic accidents can damage shallowly implanted components such as the leads and extensions.
Keep programmers and controllers dry. The clinician programmer and patient controller are not waterproof. Keep them dry to avoid damage. Advise patients to not use the patient controller when engaging in activities that might cause it to get wet, such as swimming or bathing.
Handle the programmers and controllers with care. The clinician programmer and patient controllers are sensitive electronic devices that can be damaged by rough handling, such as dropping them on the ground.
Battery care. Batteries can explode, leak, or melt if disassembled, shorted (when battery connections contact metal), or exposed to high temperature or fire.
Long-term safety and effectiveness. The long-term safety and effectiveness of this neurostimulation system has not been established beyond 5 years. Safety and effectiveness has not been established for patients with a neurological disease other than Parkinson’s disease or essential tremor, previous surgical ablation procedures, dementia, coagulopathies, or moderate to severe depression; patients under 22 years; implantation in targets other than the STN for Parkinson's disease and the VIM for essential tremor; patients with an active implantable device; patients requiring MRI.
Sterilization And Storage
Single-use, sterile device. The implanted components of this neurostimulation system are intended for a single use only. Sterile components in this kit have been sterilized using ethylene oxide (EtO) gas before shipment and are supplied in sterile packaging to permit direct introduction into the sterile field. Do not resterilize or reimplant an explanted system for any reason.
Storage environment. Store components and their packaging where they will not come in contact with liquids of any kind. Detailed information on storage environment is provided in the appendix of this manual.
Handling And Implantation
Expiration date. An expiration date (or “use-before” date) is printed on the packaging. Do not use the system if the use-before date has expired.
Recharge. Recharge information is printed on the packaging, which instructs the user to fully charge the generator before implantation.
Handle devices with care. The clinician programmer and patient controller are sensitive electronic devices that can be damaged by rough handling, such as dropping them on the ground.
Care and handling of components. Use extreme care when handling system components. Excessive heat, excessive traction, excessive bending, excessive twisting, or the use of sharp instruments may damage and cause failure of the components.
Package or component damage. Do not implant a device if the sterile package or components show signs of damage, if the sterile seal is ruptured, or if contamination is suspected for any reason. Return any suspect components to Abbott Medical for evaluation.
Exposure to body fluids or saline. Prior to connection, exposure of the metal contacts, such as those on the connection end of a lead or extension, to body fluids or saline can lead to corrosion. If such exposure occurs, clean the affected parts with sterile, deionized water or sterile water for irrigation, and dry them completely prior to lead connection and implantation.
Skin erosion. To avoid the risk of skin erosion, implant components at the appropriate depth and inform patients to avoid touching their skin where components are implanted. The IPG should be placed into the pocket, at a depth not to exceed 4.0 cm (1.57 in), with the logo side facing toward the skin surface.
System testing. To ensure correct operation, always test the system during the implant procedure, before closing the neurostimulator pocket, and before the patient leaves the surgery suite.
Multiple leads. When multiple leads are implanted, route the lead extensions so the area between them is minimized. If the lead extensions are routed in a loop, the loop will increase the potential for electromagnetic interference (EMI).
Abandoned leads and replacement leads. The long-term safety associated with multiple implants, leads left in place without use, replacement of leads, multiple implants into the target structure, and lead explant is unknown.
Placement of lead connection in neck. The lead-extension connector should not be placed in the soft tissues of the neck due to an increased incidence of lead fracture.
Hospital And Medical Environments
Electrical medical treatment. In the case that a medical treatment is administered where an electrical current is passed through the body from an external source, first deactivate the IPG by setting all electrodes to off, turning stimulation off, and setting amplitude to zero. Regardless if the device is deactivated, take care to monitor the device for proper function during and after treatment.
High-output ultrasonics and lithotripsy. The use of high-output devices, such as an electrohydraulic lithotriptor, may cause damage to the electronic circuitry of an implanted IPG. If lithotripsy must be used, do not focus the energy near the IPG.
Ultrasonic scanning equipment. The use of ultrasonic scanning equipment may cause mechanical damage to an implanted neurostimulation system if used directly over the implanted system.
External defibrillators. The safety of discharge of an external defibrillator on patients with implanted neurostimulation systems has not been established.
Therapeutic radiation. Therapeutic radiation may damage the electronic circuitry of an implanted neurostimulation system, although no testing has been done and no definite information on radiation effects is available. Sources of therapeutic radiation include therapeutic X rays, cobalt machines, and linear accelerators. If radiation therapy is required, the area over the implanted IPG should be shielded with lead. Damage to the system may not be immediately detectable.
Electrocardiograms. Ensure the neurostimulator is off before initiating an electrocardiogram (ECG). If the neurostimulator is on during an ECG, the ECG recording may be adversely affected, resulting in inaccurate ECG results. Inaccurate ECG results may lead to inappropriate treatment of the patient.
Home And Occupational Environments
Patient activities and environmental precautions. Patients should take reasonable care to avoid devices that generate strong EMI, which may cause the neurostimulation system to unintentionally turn on or off. Patients should also avoid any activities that would be potentially unsafe if their symptoms were to return unexpectedly. These activities include but are not limited to climbing ladders and operating potentially dangerous machinery, power tools, and vehicles. Sudden loss of stimulation may cause patients to fall or lose control of equipment or vehicles, injure others, or bring injury upon themselves.
Control of the patient controller. Advise patients to keep the patient controller away from children and pets in order to avoid potential damage or other hazards.
Activities requiring excessive twisting or stretching. Patients should avoid activities that may put undue stress on the implanted components of the neurostimulation system. Activities that include sudden, excessive or repetitive bending, twisting, or stretching can cause component fracture or dislodgement. Component fracture or dislodgement may result in loss of stimulation, intermittent stimulation, stimulation at the fracture site, and additional surgery to replace or reposition the component.
Activities requiring coordination. Loss of coordination is a potential side effect of DBS therapy. Patients should exercise reasonable caution when participating in activities that require coordination, including those that they were able to perform prior to receiving DBS therapy (for example, swimming).
Bathing. Patients should exercise reasonable caution when bathing.
Component manipulation by patient. Advise your patient to avoid manipulating the implanted system components (e.g., the neurostimulator, the burr hole site). This can result in component damage, lead dislodgement, skin erosion, or stimulation at the implant site. Manipulation may cause device inversion, inhibiting the ability to use the magnet to start or stop stimulation.
Scuba diving or hyperbaric chambers. Patients should not dive below 30 m (100 ft) of water or enter hyperbaric chambers above 4.0 atmospheres absolute (ATA). Pressures below 30 m (100 ft) of water (or above 4.0 ATA) could damage the neurostimulation system. Before diving or using a hyperbaric chamber, patients should discuss the effects of high pressure with their physician.
Skydiving, skiing, or hiking in the mountains. High altitudes should not affect the neurostimulator; however, the patient should consider the movements involved in any planned activity and take precautions to avoid putting undue stress on the implanted system. Patients should be aware that during skydiving, the sudden jerking that occurs when the parachute opens may cause lead dislodgement or fractures, which may require surgery to repair or replace the lead.
Wireless use restrictions. In some environments, the use of wireless functions (e.g., Bluetooth® wireless technology) may be restricted. Such restrictions may apply aboard airplanes, near explosives, or in hazardous locations. If you are unsure of the policy that applies to the use of this device, please ask for authorization to use it before turning it on. (Bluetooth® is a registered trademark of Bluetooth SIG, Inc.)
Consumer goods and electronic devices. Magnetic interference with consumer goods or electronic devices that contain magnets, such as mobile phones and smart watches, may unintentionally cause the neurostimulation system to turn on or turn off or affect communication between the device and generator however, it will not change the prescribed programmed parameters. Patients should be advised to keep their mobile phones and smart watches at least 15 cm (6 in.) away from the generator and avoid placing any smart device in a pocket near the generator. If a patient is concerned about a smart device interacting with their neurostimulation system, consider disabling magnet mode. For more information about setting the magnet mode, refer to the clinician programmer manual or contact Technical Support.
Household appliances. Household appliances that contain magnets (e.g., refrigerators, freezers, inductive cooktops, stereo speakers, mobile telephones, cordless telephones, standard wired telephones, AM/FM radios, and some power tools) may unintentionally cause the neurostimulation system to turn on or turn off.
Therapeutic magnets. Patients should be advised to not use therapeutic magnets. Therapeutic magnets (e.g., magnets used in pillows, mattress pads, back belts, knee braces, wrist bands, and insoles) may unintentionally cause the neurostimulation system to turn on or off.

Do not place electrodes near or in contact with flammable materials.
Pooling hazard. Flammable solutions may pool under the patient or in body depressions, such as the umbilicus, and in body cavities, such as the vagina. Remove fluids pooled in body depressions and cavities before using the generator.
Ignition hazard. Be aware of and take care to avoid the danger of ignition of endogenous gasses (e.g., cotton and gauze saturated with oxygen may be ignited by sparks produced during normal use of the generator).
Risk of RF burns and unintended stimulation. Do not turn the generator power on while touching any electrodes or probes. Do not place a generator-connected electrode that is not being used in contact with the patient.
Risk of RF burns to patient. This device presents a risk of RF burns to the patient under certain conditions. Physicians need to be aware of the following warnings:
Ensure the patient does not come into contact with metal parts of the table and its accessories. Antistatic sheeting is recommended.
Avoid skin-to-skin contact between different parts of patient’s body (for example between the arms and the body of the patient). Use dry gauze if necessary.
Avoid using physiological monitoring equipment during a procedure. If monitoring is required, place monitoring electrodes as far as possible from the electrode. Monitoring devices that use needle electrodes are not recommended. In all cases, monitoring systems with high-frequency current limiting devices are recommended.
Connection of a patient to high-frequency surgical equipment and to electromyograph or evoked response equipment simultaneously may result in burns at the site of the electrodes and possible damage to the applied parts.
Position all cables to the electrode and grounding pad (also known as the return electrode, dispersive electrode, or neutral electrode) to avoid contact with other electrodes and other metal objects.
Place temporarily unused electrodes connected to the generator in a container or area that is electrically isolated from the patient. Never place a generator-connected electrode that is not being used in contact with the patient. When not in use, place accessories in a clean, dry, highly visible area away from patient contact.
When not in use, place accessories in a clean, dry, highly visible area away from patient contact.
Only use grounding pads listed in the Accessories section of this manual. See "Appendix B: System Components and Accessories" (page 1).
When positioning the grounding pad, select a well-vascularized muscular site with proximity to the procedure. See "Applying the Grounding Pad" (page 20).
Place the long side of the grounding pad perpendicular to the direction of the current flow from the operative site. See "Applying the Grounding Pad" (page 20).
Do not place the grounding pad over scars, bony prominences, prostheses, hair, or EKG electrodes.
Do not place the grounding pad in a location where fluids may pool.
If the patient is sedated, place your hand on the backside of the grounding pad, while still leaving it attached to the patient. If the grounding pad is unreasonably hot (a temperature greater than 46°C), stop the procedure by pressing the Emergency Stop button.
If the patient complains of heating at the grounding pad site, stop the procedure and remove the grounding pad from the patient.
Before applying power to the electrodes, ensure that the entire area of the grounding pad is firmly adhered to a suitably prepared and appropriate area of the patient’s body as defined in the grounding pad instructions for use.
If the continuity monitor alarm is triggered, remove and discard the grounding pad. Place a new grounding pad on a fresh patch of skin.
If unexpected parameter readings are observed that do not correspond to the preset values, halt the procedure immediately by pressing the Emergency Stop button. Do not operate the equipment again until the source of the problem is identified and corrected.
Interference with active implants. Check whether the patient has a cardiac pacemaker or other active implantable device and, if so, obtain qualified advice before using the generator. Operating the generator may interfere with or damage the implanted device.
Redirection of high-frequency currents. Check whether the patient has an electrically conductive implant and, if so, obtain qualified advice before using the generator. Operating the generator may cause concentration or redirection of high-frequency currents.
Interference with other equipment. During RF lesioning procedures, the radiated electrical fields may interfere with other electrical medical equipment. See "Minimizing Electromagnetic Interference" (page 5).
Shortwave or microwave equipment. Operation in close proximity to shortwave or microwave therapy equipment may produce instability in the applied parts.
Apparent low output or failure of equipment. If low output is observed or the equipment does not function correctly at normal operating setting, check the grounding pad and its connections.
Risk of patient injury. Do not use endoscopically. The accessories are not appropriate for endoscopic use.

Warnings
71398 MAT-2006979 v2.0 | Item approved for U.S. use only.
The following warnings, precautions, and potential adverse events apply when performing MRI scans on Abbott MR Conditional SCS/DRG systems.
Warnings
Unapproved components. Do not perform an MRI scan on patients who have any components of a neurostimulation system that are unapproved for use in an MR environment. Serious patient injury could occur.
Abandoned devices. Do not perform an MRI scan on patients who have an incomplete neurostimulation system, where a lead is present without the IPG or disconnected from the system. Serious patient injury could occur.
Nonfunctional leads. Do not perform an MRI scan on patients when the “MRI is Not Advised. There may be a problem with the implanted lead(s)” message displays when attempting to enter MRI mode on the patient controller. MRI scans of nonfunctional leads may result in excessive heating occurring at the location of the implanted lead electrodes and serious patient injury.
Location of implanted system. To meet the MR Conditional requirements, components must be implanted according to the approved locations specified by the MRI labeling. The MR Conditional leads must be implanted in the epidural space and routed subcutaneously to the IPG pocket. Two leads should travel in close proximity to one another from the IPG to the spine. Lead tips can be located at different spinal epidural levels. MRI scans of implants that are not located in approved locations can possibly result in increased unintended stimulation, excessive heating at the lead electrodes, and serious patient injury.
Location of RF transmit-receive coils [Select systems only, refer to the MR Procedure Information to determine applicability]. Head or extremity MRI scans can be conducted safely using a Detachable Head or Extremity RF transmit-receive coil when no parts of the implanted neurostimulation system are within the transmit-receive coil according to the conditions specified for each system in the MRI labeling. This can be confirmed with X-ray imaging of the neck, head, and extremity regions or by referring to the patient records.
Skin erosion. Do not perform an MRI scan on patients who have any portion of their implanted system exposed due to skin erosion. The MRI scan may result in excessive heating of the system and serious patient injury.
Neurostimulation trial systems. Do not perform an MRI scan on patients who have an external neurostimulation trial system or any components that are not fully implanted. Serious patient injury could occur.
Multiple neurostimulation systems. Do not perform an MRI scan on patients who have multiple MR Conditional neurostimulation systems for pain (multiple IPGs for pain). MRI scans may result in excessive heating of the lead electrodes and serious patient injury.
Other implanted medical devices. Prior to an MRI examination, determine whether the patient has multiple medical device implants, either active medical device implants (such as deep brain stimulation systems, implantable cardiac defibrillators, pacemakers) or passive medical device implants (such as spinal hardware, stents). Of all medical device implants, the most restrictive MRI exposure requirements must be used. Do not conduct an MRI scan if any conditions or implants prohibit it, as serious patient injury could occur. If you are unclear what implants are present, perform an X‑ray to determine the implant type and location.
Imaging with atoms other than hydrogen. Do not conduct MRI scans with nonproton scanning frequencies (such as 13C, 23Na, or 31P). Frequencies other than 64 MHz could cause device damage, excessive heating, and serious patient injury.
MRI system type. Only use 1.5T cylindrical-bore magnet, horizontal field-orientation MRI systems. Do not scan with other MRI systems, such as 1.0T and 3.0T machines or vertical field orientation machines, as device damage, excessive heating of implanted components, and serious patient injury could occur.
Patient position. Do not scan with the patient in any prone positions or “superman” positions (where the patient's arm is raised above his or her head). Use of these positions could cause device damage and excessive heating of implanted components, which could result in serious patient injury.
Operating mode. Do not conduct MRI scans in first-level controlled or second-level controlled operating mode. These modes allow higher levels of RF energy and may cause excessive heating of implanted components, which could result in serious patient injury.
SAR or B1+rms limits. For scans requiring maximum SAR <2 W/kg or specific maximum B1+rms value, personnel knowledgeable in MR safety should be involved to optimally plan the scan and actively monitor SAR or B1+rms levels during the scan. Ensure the scanner displays the SAR or B1+rms value prior to starting the scan. Exceeding the SAR or B1+rms limits may cause excessive heating of implanted components, which could result in serious patient injury.
Transmit coils. Only use circularly polarized transmit coil designs. Do not scan with other transmit coil designs (for example, linear, phased-array, or saddle) as serious patient injury could occur.
Active scan time. The total active scan time must be limited to 30 minutes per session with a wait time of 30 minutes between sessions. Exceeding the active scan time limit increases the risk of excessive heating and serious patient injury.
Fever. Before an MRI scan, determine the patient's body temperature. If the patient has a fever, do not perform an MRI scan. The MR Conditional evaluation has been performed for patients with a typical body temperature of 37°C (98.6°F). Elevated body temperature in conjunction with tissue heating caused by the MRI scan could result in excessive heating of implanted components and serious patient injury.
MRI Mode patient instructions. A paired patient controller or clinician programmer is required to disable MRI Mode. The inability to disable MRI Mode would require device replacement surgery to restore therapy. Provide the following instructions to patients:
Prior to enabling MRI Mode
While in MRI Mode
Disabling MRI Mode. An inability to disable MRI Mode will occur if the patient controller is no longer paired to the IPG and there is no previously paired clinician programmer available or if the clinician programmer lost its Bluetooth® wireless connection pairing to the IPG. The inability to disable MRI Mode would require device replacement surgery to restore therapy.
Precautions
External devices. Do not allow external control devices into the scanner magnet room, such as a programmer, controller or charging system. Because these devices contain ferromagnetic material, they can be affected by the MRI magnet, may present a projectile hazard and are considered MR Unsafe.
Electromagnetic interference (EMI). Some electrical equipment, such as an MRI machine, may generate enough EMI to interfere with the operation of the internal or external electronic components of a neurostimulation system if the equipment is too close to the system component. To mitigate the effects of possible EMI, increase the distance between the electrical equipment and the system component that is affected and try performing the operation again.
Potential Adverse Events
Lead electrode heating resulting in patient discomfort, tissue damage or serious patient injury
IPG heating resulting in tissue damage in the implant pocket or patient discomfort or both
Induced currents on leads resulting in overstimulation or shocking sensations
Damage to the IPG or leads causing the system to fail to deliver stimulation or causing the system to deliver overstimulation
Damage to the functionality or mechanical integrity of the IPG resulting in the inability to communicate with the IPG
Movement or vibration of the IPG or leads
The following warnings, precautions and potential adverse events apply when performing MRI scans on Abbott MR Conditional DBS systems.
Warnings
Unapproved components. Do not perform an MRI scan on patients who have any components of a neurostimulation system that are unapproved for use in an MR environment.
Abandoned devices. Do not perform an MRI scan on patients who have any abandoned neurostimulation devices, such as an implantable pulse generator (IPG), lead, extension or adapter.
Nonfunctional leads or extensions. Do not perform an MRI scan on patients with broken or intermittent MR Conditional leads or extensions, or impedance measurements not within the impedance limits. MRI scans of patients with nonfunctional leads may result in higher than normal heating occurring at the location of the implanted lead electrodes.
Location of implanted system. To meet the MR Conditional requirements, components must be implanted according to the approved locations specified by the MRI labeling. Implant location can be confirmed with X-ray imaging or by referring to the patient records. The MR Conditional leads and extensions must be fully implanted under the skin and routed on the same side of the body as the IPG pocket.
Routing multiple leads and extensions to the same IPG. If multiple MR Conditional leads and extensions are routed to the same IPG, they should be routed in close proximity on the same side of the body as the IPG. Nonadjacent leads and extensions can result in increased unintended stimulation or heating at the lead electrodes.
Partially implanted or exposed components. Do not perform an MRI scan on patients who have any portion of their system exposed due to partial implantation or skin erosion. The MRI scan may cause heating of the system, which could result in serious patient injury.
Multiple neurostimulation systems. If a patient is implanted with two DBS IPGs, ensure that both IPGs are set to MRI mode before scanning. If a patient is implanted with one lead-only system and one full system, follow the more restrictive MRI scanning requirements of the systems, and ensure that the IPG is set to MRI mode before scanning.
Other implanted medical devices. Scanning patients who have other MR Conditional devices is acceptable as long as all the MR Conditional requirements for each of the implanted devices are met. Do not conduct an MRI scan if any conditions or implants prohibit it. If you are unclear what implants are present, perform an X‑ray to determine the implant type and location.
Imaging with atoms other than hydrogen. Imaging with atoms other than hydrogen has not been tested and could result in serious patient injury.
Patient body temperature. Before an MRI scan, determine the patient's body temperature. If the patient has a fever, you should not perform an MRI scan.
Precautions
External devices. Do not allow external control devices, such as a patient controller or clinician programmer, into the scanner magnet room. Because these devices contain ferromagnetic material, they can be affected by the MRI magnet, may present a projectile hazard, and are considered MR Unsafe.
Electromagnetic interference (EMI). Some electrical equipment, such as an MRI machine, may generate enough EMI to interfere with the operation of the internal or external electronic components of a neurostimulation system if the equipment is too close to the system component. To mitigate the effects of possible EMI, increase the distance between the electrical equipment and the system component that is affected and try performing the operation again.
Turning off stimulation before a scan. When you set a full system into MRI mode, stimulation turns off. Carefully consider a patient’s underlying medical condition and disease symptoms before turning off a neurostimulation system when performing an MRI scan. Consult with the appropriate medical professional, such as a patient’s DBS managing clinician, to determine if it is safe to turn off stimulation to conduct an MRI scan. Do not conduct an MRI scan if stimulation needs to stay on.
Potential Adverse Events
Lead electrode heating resulting in tissue damage or serious patient injury
IPG heating resulting in tissue damage in the implant pocket or patient discomfort or both
Induced currents on leads resulting in unpleasant sensations or motor disturbances
Damage to the IPGs, leads or extensions causing the system to fail to deliver stimulation or causing the system to deliver overstimulation
Damage to the functionality or mechanical integrity of the IPG resulting in the inability to communicate with the IPG
Movement or vibration of the IPGs, leads or extensions
