ABSTRACT:
An occlusion implant device for small body lumens consisting of a micromachined monocrystalline silicon disk which has inherently spring loaded integral helical wings which when released by the insertion device anchors the implant in position. The device may be used for contraception vasco-occlusion for treatment of aneurysms and with an aperture therethrough may also be utilized as a stent. Alternatively, a micro mold of silicon may be formed and a metal or plastic disk produced by injection molding.
