Abstract
Abstract The present invention is an occlusion device adapted for implantation into a fluid flow-supporting body lumen. The occlusion device comprises a flexible support structure and a flexible fluid flow-occluding membrane that is positioned concentric with the flexible support structure. The support structure is formed from a plurality of interwoven filaments that form an axially flexible and radially compressible structure that, in its expanded state, engages the lumen. The membrane generally includes a constricted region and constriction means, such as a mechanical seal, for closing the membrane at one end. The membrane is formed from a plurality of filaments, and in one embodiment, the membrane filaments are tightly interbraided with the structure filaments to form the occlusion device. Alternatively, the membrane is separately fabricated of interwoven filaments, and is positioned either within the support structure or without the structure so as to surround the support structure.
