ABSTRACT:
An autogenous heart having a physiology similar to a native heart is formed from two muscle segments which are wrapped about a mold and divided to form four chambers. To form this heart, two segments of muscle are formed to surround a silastic balloon reinforced mold which permits gross formation of the heart. The silastic balloon is then deflated and withdrawn. The interior of the heart is subdivided; the four chambers are formed; and valves are emplaced in much the manner as in the native heart. A cardiac assist device formed from a single chamber is made in much the same manner. The cardiac assist device has a single exit vessel which is bifurcated so as to allow blood flow into the chamber as the muscle is relaxed and blood flow out of the chamber as the muscle is contracted. A further improvement over current cardiac assist devices is the use of a compression ring to occlude blood flow within the native vessel when the muscle is contracted.
