WATCHMAN™ Technology


What is the WATCHMAN™ LAA Closure Device?

The WATCHMAN™ Left Atrial Appendage Closure Technology is a device based solution designed to be permanently implanted at or slightly distal to the ostium (opening) of the left atrial appendage (LAA) to trap blood clots before they exit the LAA. The WATCHMAN™ LAA Closure Technology is a three part system consisting of transseptal access sheath, a delivery catheter and an implantable device.

 The WATCHMAN™ Device is a self-expanding nitinol frame structure with fixation barbs and a permeable polyester fabric that covers the atrial facing suface of the device. The device is preloaded within a delivery catheter. The WATCHMAN™ Device is available in 5 sizes to accomodate the unique anatomy of each patient's LAA.
