Patent ID: 8906084

Claim:
A system for treating an aneurysm, the system comprising: a hardenable fluid filling medium; at least one double-walled filling structure having an outer wall and an inner wall, wherein the at least one double-walled filling structure is adapted to be filled with the hardenable fluid filling medium so that the outer wall conforms to an inside surface of the aneurysm and the inner wall forms a generally tubular lumen providing a path for blood flow therethrough, wherein in use blood flowing through said generally tubular lumen is in direct contact with a surface of the inner wall, and wherein the at least one double-walled filling structure substantially fills the aneurysm when filled with the hardenable fluid filling medium; a drain device configured to drain blood or other fluid from a space between the aneurysm and the outer wall of the at least one double-walled filling structure so as to relieve pressure in that space wherein the drain device comprises at least one elongate tubular member having a distal portion sufficiently porous so as to receive blood or other fluid from the space therethrough, the porous distal portion having sufficient length so as to allow drainage from multiple locations in the space across the aneurysm; and a delivery catheter having an expandable support structure which can be positioned within the generally tubular lumen to carry the at least one double-walled filling structure.
