Abstract
Aneurysms are treated by filling at least one double-walled filling structure with a curable medium within the aneurysm. The filling structures may be delivered over balloon deployment mechanisms in order to shape and open tubular lumens therethrough. Scaffolds are placed into the tubular lumens in order to help maintain the shape, anchor the filling structures in place, and provide improved blood flow transition into and out of the tubular lumens.

1-107. (canceled)
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, the double-walled filling structure being adapted to be filled with a hardenable fluid filling medium such 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;
- and
- at least a first scaffold disposed within the first double-walled filling structure and anchored to the inner wall of the first filling structure at least at one location such that the at least a first scaffold is expandable within at least a portion of the first tubular lumen of the filling structure.
