ABSTRACT:
The invention prosthesis is formed by a biventricular monoblock unit which comprises a sealed case implantable in the pericardial cavity. The actuating device is formed by two membranes working respectively by elongation and by deformation, and which constitute, with the corresponding internal face of the case, respectively, the right and left ventricular spaces having preferably the same volume but totally different geometry. The actuating device is associated with supplying apparatus which provide it with supply pressures subtantially equivalent to the physiological values of the ventricular pressures. The prosthesis is furthermore associated with a mechanism for regulating the cardiac flow.
