ABSTRACT:
A surgical device is provided to reduce the size of and relieve the pressure within an aneurysm. The surgical device is comprised of catheter tubing containing a spring wound under stress. The catheter is inserted through the aneurysm to be repaired and the catheter is then pulled back leaving the spring to expand within the aneurysm. The spring has a one-way helical flap mounted between the spring coils. The flap allows the blood to flow from the swollen part of the aneurysm but not to enter it.
