摘要： An apparatus for treating an aneurysm in a blood vessel includes an occlusion element disposed on a wire, the occlusion element including a cover for covering a neck of an aneurysm and an inner anchoring member. The cover is configured to expand from a compressed configuration in a tube to an expanded configuration when advanced out of a distal end of the tube to cover the neck of the aneurysm. The cover includes a sphere of mesh material formed into a hemisphere including two layers of mesh that is formed by folding a top portion of the sphere into a bottom portion of the sphere. The inner anchoring member is coupled to and extends from the second surface of the cover and is configured to contact an interior surface of the aneurysm. The inner anchoring member may be a cylindrical stem extending from a central portion of the cover.

摘要： An apparatus for treating an aneurysm in a blood vessel includes a wire to be advanced within a tube and an occlusion element disposed on the wire. The occlusion element includes a cover and an inner anchoring member. The occlusion element is configured to fit within the tube and slide out of an opening at distal end of the tube in response to movement of the wire. The cover is configured to expand to an expanded configuration when advanced into the aneurysm, wherein the cover comprises a diameter that is greater than the diameter of a neck portion of the aneurysm and is configured such that a first portion of the cover contacts an interior surface of the aneurysm and a second portion covers the neck portion of the aneurysm. The inner anchoring member extends from the cover portion and is configured to contact the interior surface of the aneurysm.
