AmplatzerTM PFO

FIRST TO MARKET
STILL FIRST WORLDWIDE

Industry-Leading PFO Solution

The first occluder developed specifically for patent foramen ovale (PFO) closure continues to leverage its role in the industry, with data conclusively demonstrating the excellent safety profile of the AmplatzerTM PFO Occluder.1

The AmplatzerTM PFO Occluder’s design features are responsible for its success.

  • DURABLE NITINOL WIRE MESH WITH POLYESTHER FABRIC THREAD

    Excellent visibility under flouoro

  • ASYMMETRIC DOUBLE DISC DESIGN

    Minimizes material in the left atrium*

  • INTAGLIO WIRE TREATMENT

    Designed to reduce nickel leaching2

Avoiding Complexity in Closure

Implanting the AmplatzerTM PFO Occluder is easy and straightforward, with no need for a lengthy learning curve for successful insertion.

Unique Self-Expanding Discs

Linked by a short-connecting waist, the discs align to the PFO with no need for an additional “locking” step

Low-Profile Delivery

8F & 9F introducer sheaths for multiple sizes (18, 25, 35 mm) enable treatment of patients with smaller vasculature

Fully Recapturable, Repositional

This allows for confirmation of proper placement prior to final release of the device

Engineered to Fit Anatomical Differences

There are multiple device sizes to address cardiovascular structural differences. In addition, the flexible, narrow waist of the device ensures that each disc is well apposed to the septal wall.

Important safety information

AMPLATZERTM PFO OCCLUDER
INDICATION FOR USE


The AMPLATZERTM PFO Occluder is indicated for percutaneous transcatheter closure of a patent foramen ovale (PFO) to reduce the risk of recurrent ischemic stroke in patients, predominantly between the ages of 18 and 60 years, who have had a cryptogenic stroke due to a presumed paradoxical embolism, as determined by a neurologist and cardiologist following an evaluation to exclude known causes of ischemic stroke.

CONTRAINDICATIONS

  • Patients with intra-cardiac mass, vegetation, tumor or thrombus at the intended site of implant, or documented evidence of venous thrombus in the vessels through which access to the PFO is gained.
  • Patients whose vasculature, through which access to the PFO is gained, is inadequate to accommodate the appropriate sheath size.
  • Patients with anatomy in which the AMPLATZERTM PFO device size required would interfere with other intracardiac or intravascular structures, such as valves or pulmonary veins.
  • Patients with other source of right-to-left shunts, including an atrial septal defect and/or fenestrated septum.
  • Patients with active endocarditis or other untreated infections.

WARNINGS

  • Patients who are at increased risk for venous thromboembolic events should be managed with thromboembolic risk reduction regimen after the PFO Closure following standard of care.
  • Do not use this device if the sterile package is open or damaged.
  • Prepare for situations that require percutaneous or surgical removal of this device. This includes availability of a surgeon.
  • Embolized devices must be removed as they may disrupt critical cardiac functions. Do not remove an embolized occluder through intracardiac structures unless the occluder is fully recaptured inside a catheter or sheath.
  • Patients who are allergic to nickel can have an allergic reaction to this device.
  •  This device should be used only by physicians who are trained in standard transcatheter techniques. 
  •  Transient hemodynamic compromise may be encountered during device placement, which may require fluid replacement or other medications as determined by the physician.
  • Do not release the device 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)). If the device interferes with an adjacent cardiac structure, 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.
  • Ensure there is sufficient distance from the PFO to the aortic root or SVC (typically defined as 9 mm or greater as measured by echo). See Figure 6. and Figure 7. 

PRECAUTIONS

  • The safety and effectiveness of the AMPLATZERTM PFO Occluder has not been established in patients (with):
    • Age less than 18 years or greater than 60 years because enrollment in the pivotal study (the RESPECT trial) was limited to patients 18 to 60 years old
    • A hypercoagulable state including those with a positive test for a anticardiolipin antibody (IgG or IgM), Lupus anticoagulant, beta-2 glycoprotein-1 antibodies, or persistently elevated fasting plasma homocysteine despite medical therapy
    • Unable to take antiplatelet therapy
    • Atherosclerosis or other arteriopathy of the intracranial and extracranial vessels associated with a ≥50% luminal stenosis
    • Acute or recent (within 6 months) myocardial infarction or unstable angina
    • Left ventricular aneurysm or akinesis
    • Mitral valve stenosis or severe mitral regurgita- tion irrespective of etiology
    • Aortic valve stenosis (mean gradient greater than 40 mmHg) or severe aortic valve regurgitation 
    • Mitral or aortic valve vegetation or prosthesis
    • Aortic arch plaques protruding greater than 4 mm into the aortic lumen
    • Left ventricular dilated cardiomyopathy with left ventricular ejection fraction (LVEF) less than 35%
    • Chronic, persistent, or paroxysmal atrial fibrillation or atrial flutter
    • Uncontrolled hypertension or uncontrolled diabetes mellitus
    • Diagnosis of lacunar infarct probably due to intrinsic small vessel as qualifying stroke event
    •  Arterial dissection as cause of stroke
    • Index stroke of poor outcome (modified Rankin score greater than 3)
    • Pregnancy at the time of implant
    •  Multi-organ failure
  • Use on or before the last day of the expiration month that is printed on the product packaging label.
  • This device was sterilized with ethylene oxide and is for single use only. Do not reuse or re-sterilize this device. Attempts to re-sterilize this device can cause a malfunction, insufficient sterilization, or harm to the patient.
  • The AMPLATZERTM PFO Occluder device consists of a 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 notify their physicians immediately if they suspect they are experiencing an allergic reaction such as difficulty breathing or inflammation of the face or throat. Some patients may also develop an allergy to nickel if this device is implanted.
  • Store in a dry place.
  • Pregnancy – Minimize radiation exposure to the fetus and the mother.
  • Nursing mothers – There has been no quantitative assessment for the presence of leachables in breast milk.
