ABSTRACT:
A direct mechanical bi-ventricular cardiac assist device comprises a ventricular actuation cup having two independently operated diaphragms for independently actuating the right and left ventricle of the patient's heart. The pressure and timing of each diaphragm can be independently varied to maximize forward cardiac output. The ventricular actuation cup is constructed in two components including a main body section and an end piece. The diaphragm wraps around the ends of the main body section and the edges of the diaphragm are bonded to the outer surface of the main body section. Bonding of the diaphragm to the outer surface of the ventricular actuation cup eliminates lifting and tearing vectors which could result in diaphragm failure.
