LEFT ATRIAL APPENDAGE CLOSURE IMPLANT

摘要

A left atrial appendage closure implant (200) may include a support frame (210) including a first bend (240) extending from a proximal collar (212) to a second bend (242), a first segment (270) extending from the second bend (242) to a third bend (244), a second segment (272) extending from the third bend (244) to a fourth bend (246), and a third segment (274) extending from the fourth bend (246) to a distal collar (214), wherein the support frame is actuatable from a first constrained position to a second flowering position to a third mid- deployment position to a fourth unconstrained position. An implant may include a self-expanding support frame having a circumference and a central longitudinal axis, a membrane disposed over at least a portion of the support frame, and a plurality of anchors arranged into a first row and a second row such that the first row and the second row form a staggered pattern about the circumference of the support frame
