OCCLUSION DEVICE |
摘要 |
An occlusion device (e.g., for treatment of the left atrial appendage) includes a framework (10) and a biocompatible covering disposed over at least a part of the framework. The framework may include a proximal portion (14), a middle portion (16), and a distal portion (18), wherein: the proximal portion includes a first hub (20) that has a fixed first diameter; the middle portion has a second diameter and includes a plurality of beams (30) 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 (40) of strut pairs (42); and the distal portion has a third diameter. In one or more embodiments, the framework includes improved circumferential strength and minimizes foreshortening. |
