Watch how the implant keeps harmful blood clots from forming.

WATCHMAN™ Device

Left Atrial Appendage Closure

The Left Atrial Appendage Closure using the Watchman™ device is a minimally invasive treatment that can bring relief to some patients with atrial fibrillation.

Left Atrial Appendage Closure (LAAC) with Watchman is a surgical implant designed to keep harmful blood clots from forming in the left atrial appendage, thereby minimizing the risk of stroke and other clot-related conditions. The procedure can be a surgical alternative to blood thinning medication for some qualified patients.

The left atrial appendage is a thumb-sized pouch on the top of the heart. Blood clots can form in this area and break loose, traveling to the brain, lungs, and other parts of the body.

The Watchman closure device, implanted by our skilled electrophysiologists, is about the size of a quarter and looks like a tiny umbrella. It is delivered by catheter under general anesthesia. The device is inserted through the groin into the femoral artery, assisted by radiologic and ultrasound technology. Implanting the LAAC is a one-time procedure – it does not have to be replaced and isn’t visible outside the body.

Talk to you cardiologist about whether you may be a candidate for LAAC.
