DEVICES AND METHODS FOR CLOSING A LEFT ATRIAL APPENDAGE

Abstract:

Using a delivery system, a disk is introduced into a left atrium (LA) of a heart of a subject. The left atrial appendage (LAA) is everted into the LA by, the from within the LAA, grasping tissue of the LAA, and pulling the LAA through an ostium of the LAA and into the LA. Within the LA, the disk is expanded, and the perimeter of the everted LAA is sandwiched between a periphery of the disk and the wall around the ostium such that the everted LAA covers the ostium. The everted LAA is secured covering the ostium by anchoring the periphery of the disk around the perimeter of the everted LAA. Other embodiments are also described.
