Abstract

An aneurysm occlusion device has a bulbous body portion and an anchor. The body portion is sized to be received within an aneurysm and the anchor is sized and shaped to engage an interior surface of the vessel'"'"'s wall. The body portion and the anchor are integrally formed of a resilient fabric permitting the occlusion device to be collapsed for deployment and resiliently self-expanded to include the aneurysm.

Claims

1. An aneurysm occlusion device for occluding an aneurysm in a vessel of a patient'"'"'s body, comprising a bulbous body portion sized to be received within the aneurysm, an anchor sized and shaped to engage an interior 10 surface of the vessel'"'"'s wall, and a pair of clamps;

the body portion and the anchor being integrally formed of a resilient fabric permitting the occlusion device to be collapsed for deployment and resiliently self-expand to occlude the aneurysm;

one of said clamps being carried by the anchor, the other of said clamps being carried by and enclosed within an interior of the body portion.

2. The aneurysm occlusion device of claim 1 wherein the resilient fabric is formed of a plurality of wire strands having ends, the clamps securing the ends of the wire strands.

3. The aneurysm occlusion device of claim 1 wherein the interior of the body portion is hollow and defines a recess sized to receive the clamp carried by the body portion to provide the body portion with an atraumatic surface.

4. The aneurysm occlusion device of claim 1 wherein the aneurysm has an enlarged body and a narrowed neck connecting the body to a wall of the vessel, the aneurysm occlusion device further comprising a generally tubular central portion disposed between and connecting the body portion and the anchor, the central portion being sized and shaped to be received within the neck of the aneurysm.

5. A medical occlusion device comprising a body, an anchor and a reduced diameter, generally tubular central portion disposed between and connecting the body and the anchor;

the body, the anchor and the central portion being integrally formed of a resilient fabric formed of a plurality of wire strands and permitting the occlusion device to be collapsed for deployment and resiliently self-expand;

ends of the wire strands being secured to one another with a first set of secured ends being adjacent the body portion, the first set of secured ends being received within a recess adjacent a top of the body portion, thereby providing the body portion with an atraumatic surface.

6. The aneurysm occlusion device of claim 5 wherein the body has a hollow interior, the recess comprising said hollow interior of the body.
