About Vine™
Vine™ is a permanent filter for stroke prevention in individuals with abnormal heart rhythm (atrial fibrillation, or AF). In people with AF, blood clots formed in the heart may travel through the arteries in the neck (carotid arteries) to the brain and cause stroke. The Vine™ filter intercepts these clots before they can reach the brain, thereby limiting the risk of stroke. Vine™ is implanted into the carotid arteries by a thin needle in a quick and simple procedure, which does not require general anesthesia.
