Abstract
An epicardial implant having a positioning device that defines an open interior. The positioning device is configured to be detachably coupled with an implant delivery device such that the positioning device may be detached from the implant delivery device after the implant is in place about an atrial appendage. The positioning device has first and second sides with a distal end that couples the first and second sides. The implant includes an expandable cuff coupled with the positioning device. The positioning device is configured to selectively move the expandable cuff toward and away from an atrial appendage to position the expandable cuff in a desired position relative to the atrial appendage. The expandable cuff is expandable into at least a portion of the open interior of the positioning device to physically occlude a base of the atrial appendage following placement of the expandable cuff into the desired position.
