Patent ID: 7857847

Claim:
A heart prosthesis implantable in a pericardial cavity of a patient, said prosthesis being configured to replace natural left and right ventricles of said patient after their removal and comprising a rigid body in which artificial left and right ventricles are arranged, each of the artificial ventricles comprising a flexible membrane that is: configured to beat under the action of a hydraulic fluid, and arranged in a cavity divided in a leaktight manner by said membrane into two chambers, one of which is intended for circulation of blood, and the other of which is filled with said hydraulic fluid, the hydraulic fluid chamber of each artificial ventricle being connected to an individual hydraulic actuator while the blood chamber of the artificial left ventricle comprises an orifice of connection to the natural left auricle and means of connection to the aorta, and the blood chamber of the artificial right ventricle comprises an orifice of connection to the natural right auricle and means of connection to the pulmonary artery, the axes of said orifices of connection to the natural auricles being co-planar, and said artificial ventricles having, parallel to the plane of said axes of said orifices general directions arranged in a V-shape, such that said ventricles approach each other as they move away from said orifices of connection to the natural auricles, wherein: said axes of said orifices of connection to the natural auricles are at least approximately parallel; said V-shaped arrangement of the artificial left and right ventricles is asymmetrical with respect to said axes, an angle formed between the general direction of the artificial right ventricle and the axis of said orifice of connection to the natural right auricle greater than the angle formed between the general direction of the artificial left ventricle and the axis of said orifice of connection to the natural left auricle; and said individual hydraulic actuators, associated respectively with said artificial left and right ventricles are arranged near each other, on the side of said artificial left ventricle.
