Totally implantable cardiac prosthesis having floating membranes, quick connectors and replaceable elements

Abstract

Abstract Implantable cardiac prosthesis consisting of a single-shell module (1) with quick connections and comprising two independent, biologised ventricular chambers (9, 9') which are activated separately and which are each provided with two orifices equipped with valves (5, 5'), one of the orifices serving as a blood ejection route (7) and the other as a blood admission route (3), and consisting of a separate activating and regulating device comprising an electromechanical member (2) activating a pair of membranes (10, 11), characterised in that the first membrane is a mechanical membrane (11) activated by a piston or a transmission fluid (14) pressurised by means of the said electromechanical member (2), and the second membrane is a biological floating membrane (10) in contact with the blood and moving, under the action of the first membrane (11), between the diastolic and systolic positions and, under the pressure of the blood, between the systolic and diastolic positions. <IMAGE>
