A device comprises a bag with associated actuator means which can be selectively activated to permit the expansion of the bag and its consequent filing with a body of blood which flows towards the bag, and to produce the contraction of the bag with the consequent expulsion from the bag of a body of blood which has flowed into the bag. Means are provided for selectively varying the resistance offered by the said bag to filing with the said body of blood.

Ventricular assist device, accessory therefore and method of use

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.
