Vascular Occluder with Crossing Frame Elements

An occlusion device 60 includes first and second crossing frame elements 12, 14 each being annular ring-shape, and first and second annular support elements 32, 34 connected to the crossing frame elements 12, 14. The frame and support elements 12, 14, 32, 34 are provided with covers 52, 54, 56, 58 made of a substantially impervious material. The occluder 60 may include a covering sleeve 62 of stretchable material. The vascular occluder 60 substantially blocks or reduces the flow of blood in the vessel, creating blood statis and subsequent occlusion by clot formation within the occluder 60. The structure of the frame elements 12, 14, 32, 34 ensures good edge sealing and enhanced fixation of the occluder 60 in a vessel as blood pressure impinges upon the covers of the occluder 60.
