Indication for Use: The Amplatzer™ Amulet™ Left Atrial Appendage Occluder is a percutaneous transcatheter device intended to reduce the risk of thrombus embolization from the left atrial appendage (LAA) in patients who have nonvalvular atrial fibrillation and who are at increased risk for stroke and systemic embolism based on CHADS2 or CHA2DS2-VASc scores, are suitable for short term anticoagulation therapy, and have appropriate rationale to seek a non-pharmacologic alternative to oral anticoagulation, taking into consideration the safety and effectiveness of the device.

Contraindications: The Amplatzer™ Amulet™ Left Atrial Appendage (LAA) Occluder is contraindicated for patients:

·         with the presence of intracardiac thrombus,

·         with active endocarditis or other infections producing bacteremia.

·         where placement of the device would interfere with any intracardiac or intravascular structures.

Warnings:

·         If the device is retracted while it is in the sheath, the device and the sheath must both be removed and replaced. Failure to replace both the device and the sheath may result in sheath and/or device malfunction.

·         If the device is retracted farther than the radiopaque markers (fully recaptured), the device and the sheath must both be removed and replaced. Failure to replace both the device and the sheath may result in sheath and/or device malfunction.

·         Physicians must be prepared to deal with urgent situations, such as pericardial effusion or device embolization, which can require removal of the device.

·         This device should be used only by physicians who are trained in standard transcatheter techniques. The physician should determine which patients are candidates for procedures that use this device.

·         Late pericardial effusion events were observed in the clinical study. The use of post-procedure anticoagulation therapy may be associated with an increased potential for a late pericardial effusion. Physicians should monitor for signs and symptoms of pericardial effusion and obtain appropriate imaging when indicated. Physicians should also consider routine echocardiography to screen for pericardial effusion.

·         Remove embolized devices. Do not remove an embolized device unless the device is fully captured inside a sheath.

·         The Amplatzer™ Amulet™ device contains a nickeltitanium alloy, which is generally considered safe. However, in vitro testing has demonstrated that nickel is released from this device for a minimum of 120 days. Patients who are allergic to nickel may have an allergic reaction to this device, especially those with a history of metal allergies. Certain allergic reactions can be serious; patients should be instructed to seek medical assistance immediately if they suspect they are experiencing an allergic reaction. Symptoms may include difficulty in breathing or swelling of the face or throat. While data are currently limited, it is possible that some patients may develop an allergy to nickel if this device is implanted.

·         Do not use this device if the sterile package is open or damaged.

·         The device was sterilized with ethylene oxide and is for single use only. Do not reuse or resterilize this device. Attempts to resterilize this device can cause a malfunction, insufficient sterilization, or harm to the patient.

INDICATION FOR USE

The AMPLATZER™ Septal Occluder is a percutaneous, transcatheter, atrial septal defect closure device intended for the occlusion of atrial septal defects (ASD) in secundum position or patients who have undergone a fenestrated Fontan procedure and who now require closure of the fenestration. Patients indicated for ASD closure have echocardiographic evidence of ostium secundum atrial septal defect and clinical evidence of right ventricular volume overload (such as, 1.5:1 degree of left-to-right shunt or RV enlargement).

CONTRAINDICATIONS

The AMPLATZER™ Septal Occluder is contraindicated for the following:

• Any patient known to have extensive congenital cardiac anomaly which can only be adequately repaired by way of cardiac surgery.
• Any patient known to have sepsis within 1 month prior to implantation, or any systemic infection that cannot be successfully treated prior to device placement.
• Any patient known to have a bleeding disorder, untreated ulcer, or any other contraindications to aspirin therapy, unless another antiplatelet agent can be administered for 6 months.
• Any patient known to have a demonstrated intracardiac thrombi on echocardiography (especially left atrial or left atrial appendage thrombi).
• Any patient whose size (such as, too small for transesophageal echocardiography probe, catheter size) or condition (active infection, etc.) would cause the patient to be a poor candidate for cardiac catheterization.
• Any patient where the margins of the defect are less than 5 mm to the coronary sinus, inferior vena cava rim, AV valves, or right upper lobe pulmonary vein.

WARNINGS

• Physicians must be prepared to deal with urgent situations, such as device embolization, which require removal of the device. This includes the availability of an on-site surgeon.
• Embolized devices must be removed as they may disrupt critical cardiac functions. Embolized devices should not be withdrawn through intracardiac structures unless they have been adequately collapsed within the sheath.
• Use on or before the expiration date noted on the product packaging.
• This device is sterilized using ethylene oxide and is for single use only. Do not reuse or resterilize. Attempts to resterilize the device may result in device malfunction, inadequate sterilization, or patient harm.
• Do not use the device if the packaging sterile barrier is open or damaged.
• Do not release the AMPLATZER™ Septal Occluder from the delivery cable if the device does not conform to its original configuration, or if the device position is unstable or if the device interferes with any adjacent cardiac structure (such as Superior Vena Cava (SVC), Pulmonary Vein (PV), Mitral Valve (MV), Coronary Sinus (CS), aorta (AO)). Recapture the device and redeploy. If still unsatisfactory, recapture the device and either replace with a new device or refer the patient for alternative treatment.
• Implantation of this device may not supplant the need for Coumadin™ in patients with ASD and paradoxical emboli.
• The use of echocardiographic imaging (TTE, TEE, or ICE) is required.
• Balloon sizing should be used to size the atrial septal defect using a stop-flow technique. Do not inflate the balloon beyond the cessation of the shunt (such as, stop-flow). DO NOT OVERINFLATE.
• Patients with a retro-aortic rim of less than 5 mm in any echocardiographic plane, or patients in whom the device physically impinges on (i.e. indents or distorts) the aortic root, may be at increased risk of erosion.
• Do not select a device size greater than 1.5 times the echocardiographic-derived ASD diameter prior to balloon sizing.

PRECAUTIONS

• The use of this device has not been studied in patients with patent foramen ovale.
• Use standard interventional cardiac catheterization techniques to place this device.
• Placement of the AMPLATZER™ Septal Occluder may impact future cardiac interventions, for example transeptal puncture and mitral valve repair.
• This device contains nickel-titanium alloy, which is generally considered safe. However, in vitro testing has demonstrated that nickel is released from this device for a minimum of 60 days. Patients who are allergic to nickel may have an allergic reaction to this device, especially those with a history of metal allergies. Certain allergic reactions can be serious; patients should be instructed to seek medical assistance immediately if they suspect they are experiencing an allergic reaction. Symptoms may include difficulty in breathing or swelling of the face or throat. While data is currently limited, it is possible that some patients may develop an allergy to nickel if this device is implanted.

MR Conditional to 3.0 Tesla

Caution should be used if an MRI is performed with a magnetic field of >3.0 tesla. Through non-clinical testing, the AMPLATZER™ device has been known to be MR Conditional at field strengths of 3.0 tesla or less with a maximum whole-body-averaged specific absorption rate (SAR) of 3.83 W/kg at 1.5 tesla and 5.57 W/kg at 5.0 tesla for a 20-minute exposure to a B1 of 118 μT. The AMPLATZER™ device should not migrate in this MR environment. Non-clinical testing has not been performed to rule out the possibility of migration at field strengths higher than 3.0 tesla. In this testing, the device produced a temperature rise of 1.1°C at 1.5 tesla and 1.6°C at 5.0 tesla. MR image quality may be compromised if the area of interest is in the exact same area or relatively close to the position of the device.
