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.

Abstract: Occlusion device for an atrial appendage, the device having proximal and distal ends and a central axis and comprising a cage-like structure formed of struts, the struts having proximal strut ends and distal strut ends, wherein at the proximal end of the device the struts extend towards the central axis and are connected to each other at their proximal strut ends, and wherein at least some of the struts are connected to each other at their distal strut ends within the cage-like structure so that the struts form an atraumatic distal end of the device.
