ABSTRACT:
A single cardiac ventricular assistance device intended to integrate the ctions of a ventricular assistance device (V.A.D.) proper and of an aortic balloon pump (IABP) includes a single energy source which causes the simultaneous rhythmic contraction of two chambers which are intended to be filled with blood. One of the contractible chambers has two one-way valves for the inlet and outlet of the blood respectively, while the other has a single inlet-outlet connector without valves for connection to the outlet of the first chamber downstream of its outlet-valve portion.
