摘要：
A left atrial appendage closure implant may include a support frame including a first bend extending from a proximal collar to a second bend, a first segment extending from the second bend to a third bend, a second segment extending from the third bend to a fourth bend, and a third segment extending from the fourth bend to a distal collar, 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.
