Abstract: A system for treating an aneurysm comprises an elongate flexible shaft and an expandable member. An expandable scaffold is disposed over the expandable member and may be expanded from a collapsed configuration to an expanded configuration. A double-walled filling structure is disposed over the scaffold and has an outer wall and an inner wall. The filling structure is adapted to be filled with a hardenable fluid filing medium so that the outer wall conforms to an inside surface of the aneurysm and the inner wall forms a substantially tubular lumen to provide a path for blood flow. In the expanded configuration the scaffold engages the inner wall of the filling structure. A tether is releasably coupled with the filling structure and the flexible shaft thereby constraining axial movement of the structures relative to each other.

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.
