The Watchman device is a small, fabric-covered device permanently placed in the opening of the left atrial appendage in the left atrium of your heart. The device is designed to permanently close off the left atrial appendage, the source of a majority of stroke-causing blood clots.
Implanting the Watchman device is a one-time procedure that usually lasts about an hour and is conducted with general anesthesia. The Watchman device is implanted through a small incision at the top of your leg using a catheter. Following the procedure, patients will need to stay in the hospital for a minimum of 24 hours.
The body takes approximately 45 days to heal and grow a natural lining over the device. After 45 days of healing, most patients can then discontinue the blood-thinners they were previously prescribed to lessen the risk of stroke.
