Device Keeps Clots from Entering Blood Stream

The Watchman device is designed to keep harmful sized blood clots that form in the left atrial appendage from entering the blood stream, potentially causing a stroke. The device is permanently placed just behind or at the opening of the left atrial appendage.

Using standard techniques, similar to the ones used in commonly performed angioplasty procedures, the Watchman device is guided into the heart through a catheter. Once the catheter is in the correct position, pictures of the heart are taken in order to take appropriate measurements of the left atrial appendage. The measurements will determine which size Watchman device to use.

The reSept ASD Occluder is the first structural heart occluder with a metal-free, bioresorbable frame. The novel implant is designed to overcome the limitations of current transcatheter occluders. It is hoped the design will reduce the risk of complications associated with the long-term presence of metal in the heart and to preserve future treatment options requiring transseptal intervention.
