This study will assess the safety and performance of the Vine™ Embolic Protection System (embolic filtering device) in atrial fibrillation (AF) patients on top of oral anticoagulants (OAC), and remain at high risk for stroke recurrence. All patients will receive bilateral implants in the common carotid arteries


The Vine™ filter (Vine™ or implant) is a permanent carotid filter designed for stroke prevention in AF patients taking OAC at high stroke risk (CHA2DS2-VASc ≤ 4 and stroke history). This patient population accounts for ~20% of the entire AF population, which is ~300K/year in the United State and EU. The implant is designed to exclude emboli > 1.2mm in size from reaching the anterior circulation. In AF patients, approximately 80% of strokes are total or partial anterior circulation strokes caused by occlusions of the main branches of the Circle of Willis, mainly M1-2, and rarely A1-2. The diameter of these branches, in the majority of cases, is > 1.5 mm
