Patent ID: 8870941

Claim:
A system for treating an aneurysm in a blood vessel, said system comprising: at least a first double-walled filling structure having an outer wall and an inner wall, wherein said double-walled filling structure is adapted to be filled with a hardenable fluid filling medium so that when the first filling structure is deployed across the aneurysm,the outer wall conforms to the inside surface of the aneurysm across the aneurysm and the inner wall forms a first generally tubular lumen to provide a path for blood flow across the aneurysm such that blood flow is in direct contact with the inner wall along the first generally tubular lumen; at least a first scaffold separate from the first double-walled filling structure which can be expanded within at least a portion of the first tubular lumen of the filling structure; a second double-walled filling structure having an outer wall and an inner wall, wherein said second double-walled filling structure is adapted to be placed adjacent to the first double-walled filling structure in the aneurysm and to be filled with a hardenable fluid filling medium so that when the second filling structure is deployed across the aneurysm, the outer wall conforms to the inside surface of the aneurysm across the aneurysm and to the first double-walled filling structure and forms a second generally tubular lumen to provide a path for blood flow across the aneurysm such that blood flow is in direct contact with the inner wall along the second generally tubular lumen; and at least a second scaffold separate from the first scaffold and the double-walled filling structures which can be expanded within at least a portion of the second tubular lumen of the second double-walled filling structure.
