摘要:
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.
