have left blood thinners
behind with WATCHMAN.

Answer a few questions about your AFib to see if WATCHMAN is right for you.

One Time. For a Lifetime.

AFib doesn’t have to mean a lifetime of blood thinners. WATCHMAN is a one‑time, minimally invasive procedure that reduces stroke risk and bleeding worry for life.



WATCHMAN Reduces the Risk of Stroke from Non‑valvular AFib

There’s an alternative to blood thinners for people who need one. It’s called WATCHMAN. The most implanted, FDA-approved device proven to reduce stroke risk in people with atrial fibrillation not caused by a heart valve problem (also referred to as non-valvular AFib). Watch the video to learn more and talk to your cardiologist about WATCHMAN.

Beyond Blood Thinners

Over 1/3 of people with AFib feel trapped between the fear of having a stroke and fear of the risks associated with blood thinners. In fact, more than 4 in 5 people with AFib taking a blood thinner (83%) say they would be willing to try a different treatment to help reduce their risk of stroke.1

I didn’t have any problems getting the [WATCHMAN] procedure and I feel so much better since I had it. It makes me feel good that I can get up and go and not worry.
