Abstract:
1. A method for treating an aneurysm, said method comprising: positioning at least a first double-walled filling structure substantially across the entire aneurysm, the first filling structure having a longitudinal axis; filling the at least first filling structure with a hardenable fluid filling medium so that an outer wall conforms to an inside surface of the aneurysm and an inner wall forms a first generally tubular lumen to provide a first blood flow path across the aneurysm, the inner wall in direct contact with blood flowing through the first lumen; placing at least a first scaffold within at least a portion of the first generally tubular lumen so as to maintain blood flow during the filling; positioning at least a second double-walled filling structure substantially across the entire aneurysm adjacent to and side-by-side with the first filling structure, the second filling structure having a longitudinal axis, wherein at least a portion of the longitudinal axis of the second filling structure is substantially parallel with at least a portion of the longitudinal axis of the first filling structure, wherein the second filling structure is separate and distinct from the first filling structure; filling the at least second filling structure with a fluid filling medium so that an outer wall of the second filling structure conforms to both the inside of the aneurysm and the outer wall of the first filling structure and that an inner wall of the second filling structure forms a second generally tubular lumen to provide a second blood flow path across the aneurysm; and placing at least a second scaffold within at least a portion of the second generally tubular lumen so as to maintain blood flow during the filling.
