Could a tiny neck filter stop strokes in heart patients?
NCT ID NCT05723926
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether implanting small filters in the carotid arteries (the main neck arteries) can prevent repeat strokes in people with atrial fibrillation who have already had a stroke. Participants will receive the filters plus standard blood thinners, or blood thinners alone. The goal is to see if the filters catch blood clots before they reach the brain, reducing the risk of a major stroke.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Vine Filter (a small mesh device implanted in the carotid artery to catch blood clots)
- What this could lead to
- If it works, this could offer a new way to prevent disabling strokes in people with atrial fibrillation who are already on blood thinners.
- What could go wrong
- This is a large trial but still experimental. The implant procedure carries risks like bleeding or damage to the artery, and the filter may not catch all clots. It is not yet proven to be safe or effective.
