Abstract: 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.

Abstract: An occlusion device (e.g., for treatment of the left atrial appendage) includes a framework and a biocompatible covering disposed over at least a part of the framework. The framework may include a proximal portion, a middle portion, and a distal portion, wherein: the proximal portion includes a first hub that has a fixed first diameter; the middle portion has a second diameter and includes a plurality of beams extending from the first hub to a distal portion, wherein each of the plurality of beams is connected to an adjacent beam by a first circumferentially extending column of strut pairs; and the distal portion has a third diameter. In one or more embodiments, the framework includes improved circumferential strength and minimizes foreshortening.
