Abstract
A total artificial heart for placement inside a living body comprising right and left ventricle enclosures, wherein each ventricle includes an exterior wall formed of (i) contacting wall structure and (ii) noncontacting wall structure which collectively enclose an interior volume comprised of a blood chamber and a pumping chamber. The contacting wall structure of each ventricle enclosure is configured for intercontacting relationship wherein the contacting walls of the respective ventricles form a septum which structurally separates the interior volume of the right ventricle from the interior volume of the left ventricle. The noncontacting wall structure comprises the remaining exterior wall of each ventricle enclosure. A fluid drive motor capable of reversible flow is positioned within and circumscribed by the septum and includes a flow channel therethrough which communicates between the respective pumping chambers of the right and left ventricle enclosures. A pumping fluid is contained within the pumping chambers and is responsive to the fluid drive motor to be reversibly transferred between the pumping chambers of the right and left ventricle to enlarge and contract the blood chamber and thereby simulate natural pumping action of the heart.
