Product Details

The WATCHMAN LAAC Device is a catheter-delivered heart implant designed to close the left atrial appendage (LAA). The WATCHMAN Device is permanently implanted at or slightly distal to the ostium (opening) of the LAA, which is believed to be the source of a majority of stroke-causing blood clots in people with non-valvular AF.1 By closing off the LAA to prevent the migration of blood clots from the LAA, the risk of stroke may be reduced an, over time, patients may be able to stop taking anticoagulants.
