ABSTRACT:
A one-piece prosthesis for biventricular cardiac assistance and reanimation is implanted in the right hemithorax between the diaphragm and the right lung symmetrically with respect to a diseased natural heart with which it operates in parallel. The prosthesis comprises a one-piece shell and two blood-circulating deformable-diaphragm pumps actuated by a compressed gas. The prosthesis face which rests on the patient's diaphragm is substantially flat and a substantially orthogonal face is provided with two ports for connecting the prosthesis to the natural heart while the other two connecting ports are inclined at an angle of 45.degree., connections between the ports and the natural heart being established by means of very short flexible hose elements. A system of port end-fittings serves to connect the prosthesis to the hose elements and to purge the prosthesis or to withdraw any air which may be present.
