What is the Watchman Device?

The Watchman device is a small, minimally invasive implant designed to reduce the risk of stroke in people with atrial fibrillation that is not caused by a heart valve problem. In atrial fibrillation, blood can pool in a small pouch of the heart called the left atrial appendage, where dangerous clots may form. The Watchman device permanently seals this area, preventing clots from traveling to the brain and causing a stroke.

Why is it Used?

Many patients with atrial fibrillation are prescribed blood thinners to lower their stroke risk. While these medications are effective, they can increase the risk of bleeding. For patients who cannot tolerate long-term blood thinner use, or who have lifestyle or health concerns about bleeding, the Watchman device provides an alternative, non-pharmacologic solution for stroke prevention.

How is the Watchman Device Implanted?

The procedure is performed in a hospital under general anesthesia. Using a thin, flexible tube called a catheter, the device is guided through a vein in the leg into the heart and positioned in the left atrial appendage. Once in place, the Watchman expands to seal the opening permanently. Over time, the body’s tissue grows over the device, creating a natural barrier. Most patients return home the next day and resume normal activities soon after.

Living with the Watchman Device

Following implantation, patients typically take blood thinners for a short period until the heart tissue fully heals over the device. After that, most are able to stop blood-thinning medication altogether. The Watchman provides lasting stroke protection, reduces bleeding risks associated with medication, and allows patients to live with greater peace of mind and independence.
