LEFT ATRIAL APPENDAGE OCCLUSION DEVICES AND METHODS

摘要

A catheter device is provided that includes an elongate body, an atraumatic member, an expandable member, and a locking device. The elongate body has a fluid flow lumen that is in fluid communication with an outlet port adjacent to a distal end of the elongate body. The atraumatic member can be at the tip of the elongate body. The expandable member is disposed proximal of the atraumatic tip and is configured to block an opening of the LAA. The locking device is disposed adjacent to the expandable member. The locking device has a first configuration in which the elongate body is coupled with the atraumatic member and second configuration in which the elongate body is uncoupled from the atraumatic member.
