Aneurysm neck cover for sealing an aneurysm

摘要

An aneurysm neck cover (10) is disclosed for use in occluding the flow of blood within an aneurysm. The aneurysm neck cover includes a first (30) and second (32) expandable sealing member having a circular joining member (50) and reinforcing spokes (40) which give the sealing members a slightly cupped configuration. The expandable sealing members are connected with a support element (34). When the aneurysm neck cover is deployed within the aneurysm, the first sealing member expands within the aneurysm while the second sealing member expands within an adjacent blood vessel thereby forming a seal around the mouth of the aneurysm and preventing the flow of blood within the aneurysm.
