Evaluating Percutaneous Repair Of The Atrial Septum With A Novel PFO Occluder: The PROTEA-PFO OUS Study

Brief Summary

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, and 1 year after the procedure for follow up exams. * Answer a phone call from study staff at 2 years and 3 years after the procedure to answer a survey.
