The device is then discharged into the LAA. Eventually tissue grows over the Amulet device and completely occludes the LAA. [23] The ULTRASEAL LAA device, from Cardia, is a percutaneous, transcatheter device intended to prevent thrombus embolization from the left atrial appendage in patients who have non-valvular atrial fibrillation.
