VASCULAR OCCLUDER WITH CROSSING FRAME ELEMENTS

摘要

An occlusion device includes first and second crossing frame elements each of annular ring-shape, as well as first and second annular support elements connected to respective extremities of the crossing frame elements. The frame and support elements are provided with covers made of a substantially impervious material. The occluder may include a covering sleeve of stretchable material. The occluder substantially stops or reduces the flow of blood therethrough, creating blood statis and subsequent occlusion by clot formation within the occluder. The structure of the frame elements ensures good edge sealing and enhanced fixation of the occluder in a vessel as blood pressure impinges upon the covers of the occluder.

1. A vascular occlusion device for use in occluding a body vessel, the device having first and second ends and sides, and including:
first and second frame elements made of a resilient material, the first and second frame elements being coupled to one another in crossing relationship; the first and second frame elements extending to the proximal and distal ends and sides of the device; and proximal and distal end covers extending across the proximal and distal ends of the device.
