LEFT ATRIAL APPENDAGE CLOSURE DEVICE WITH MECHANICAL JOINING ASSEMBLY

Abstract

A left atrial appendage closure device includes an expandable frame that extends between a proximal region and a distal region, with the distal region including a plurality of tines each having an engagement portion. A connection assembly secures the engagement portion of each of the plurality of tines together. The connection assembly includes a connection member having an outer surface and a ring member that is advanced over the outer surface of the connection member, the ring member including an inner annular surface and a plurality of engagement recesses extending from the inner annular surface, each of the plurality of engagement recesses accommodating the engagement portion of a corresponding one of the plurality of tines. The engagement portion of each of the plurality of tines are entrapped between the ring member and the connection member, thereby securing the plurality of distal tines.
