MEDICAL DEVICE FOR MODIFICATION OF LEFT ATRIAL APPENDAGE AND RELATED SYSTEMS AND METHODS

摘要

A medical device, system and method for modifying a left atrial appendage (“LAA”). The medical device system includes a tether anchored within the LAA and one or more tissue growth members or occluders configured to be slid over the tether and lodged within the LAA. With this arrangement, a physician may close-off the LAA with a selective number of tissue growth members to meet the varying LAA sizes as determined from imaging information while conducting the procedure.

主权项

1. A method for modifying a left atrial appendage, comprising:
positioning a catheter adjacent the left atrial appendage; pushing a medical device having tines through a lumen of the catheter; anchoring the medical device within the left atrial appendage; deploying a tissue growth member of the medical device from the catheter, the medical device rotatably coupled to a threaded pusher member; and maintaining the at least one tissue growth member in the left atrial appendage with a locking element, the locking element including multiple fingers that collapse directly dependent upon proximally moving the threaded pusher member relative to the tissue growth member.
