The goal of this clinical trial is to test a new heart device called P3 Occluder System in patients who have a small opening between the upper chambers of the heart (called a Patent Foramen Ovale or PFO) and have experienced a stroke that may be related to this heart opening. The main question it aims to answer is:
• Is the P3 Occluder System safe and effective for closing a PFO in patients who have had a stroke that could be related to a PFO.
Participants will:
* Undergo the procedure to implant the P3 Occluder System, if deemed appropriate. * Visit their doctor at 1 month, 3 months, 6 months, 1 year, and 5 years after the procedure for follow up exams. * Answer a phone call from study staff at 2 years, 3 years, and 4 years after the procedure to answer a survey.
Patient must be ≥ 18 and ≤ 65 years of age
Diagnosis of PFO, defined as visualization of microbubbles per TEE in the left atrium within three cardiac cycles from the right atrial opacification demonstrating right-to-left shunting at rest and/or during Valsalva release.
Ischemic stroke, defined as acute focal neurological deficit, presumed to be due to focal ischemia and confirmed by MRI or CT to have a neuroanatomically relevant cerebral infarct.
Modified Rankin score (mRS) ≤ 3.
Other identifiable causes of stroke, including but not limited to aortic arch plaques (protruding >4 mm into the lumen), large artery atherosclerotic disease proximal to the territory of the index stroke, an established cardioembolic source, small-vessel occlusive disease, or arterial dissection, presence of left atrial appendage thrombus.
Other arteriopathy of the intracranial or extracranial vessels with >50% stenosis proximal to the territory of the index stroke.
Intracardiac thrombus or tumor.
Myocardial Infarction (MI) or unstable angina within the previous 180 days.
