ABSTRACT:
A transmyocardial implant includes a hollow conduit inserted through a heart wall. The conduit defines a blood flow path between a heart chamber opening and a vessel opening. The heart chamber opening of the conduit is placed in communication with a chamber of the heart. A coronary vessel on an exterior of the heart wall is severed into a proximal portion and a distal portion. The distal portion of the vessel is placed into the vessel opening of the conduit. An alternative embodiment places the vessel flush with the vessel opening of the conduit.
