<p>Methods and apparatus are provided for temporarily excluding an aneurysm (101) or an arterio-venous fistula from a flow path by transluminally disposing a hollow balloon catheter structure (20) within the aneurysm so that its proximal and distal ends extend past the aneurysm while maintaining continuity of the flow path, and then injecting a synthetic molding material or a biological hardening agent (45) into the aneurysm cavity (108) to cause solidification of the volume within the cavity. Once the material within the excluded aneurysm has solidified, the balloon catheter structure (20) is deflated and removed, so that the hardened mass forms a new lining for the organ or vessel, and relieves the weakened tissue of the aneurysm or fistula from further flow-induced stress.</p> |
