Device for cardiac ventricular assistance, especially for the recovery of depressed myocardial function and maintenance of the body's vital functions

摘要

A single device 1 designed to incorporate the function of ventricular assistance (V.A.D.) proper and the function of an aortic balancing pulse (I.A.B.P.) comprising two volumes 5, 6 designed to be invaded by the blood mass and capable of being rhythmically contracted through the effect of an outside energy source 25, 26. Of the said contractile volumes, one 6 which is located upstream of the other is provided with two one-way valves, inlet 8 and outlet 9 valves for blood respectively, while the other 5, which is located downstream from and fluidynamically in series with respect to the first volume, can be passed through by the blood flow originating from first volume 6.
