ABSTRACT:
Springs are used to form cardiovascular grafts.
A tightly wound spring coated with carbon while in a stretched position will have a biocompatible interior surface which provides an unobstructed passageway for blood. Fabric sleeves may be employed around springs to improve the fluid integrity of the interior surfaces.
Springs may also be used to join blood vessel segments by puncturing one segment of the blood vessel with a first end of a spring, coiling the spring therearound, puncturing a second segment of the blood vessel with a second end of the spring and coiling the spring therearound.
