Occlusion device with internal fastener

Abstract

An occlusion device comprises a plurality of wires made of shape memory material, braided to form an expanded shape having a first end and a second end, a first fastener coupled to the plurality of wires at the first end, and a second fastener coupled to the plurality of wires at the second end, wherein the first fasteners is placed in the interior of the device. Another occlusion device comprises a first disk shaped portion made of shape memory material, a first fastener configured to fasten one end of the first disk shaped portion, a second disk shaped portion made of shape memory material, a second fastener configured to fasten one end of the second disk shaped portion, and a tension member connecting the first portion and the second portion, wherein the first fasteners is placed in the interior of the device.
