A heart-assist device which includes a flexible catheter carrying at least a ventricular balloon, such balloon corresponding in size and shape to the size and shape of the left ventricle in the heart being assisted, the ventricular balloon being progressively inflated creating a wave-like pushing effect and deflated synchronously and automatically by means of a control console which responds to heart signals from the catheter or elsewhere, the catheter optionally also carrying an aortic balloon inflated and deflated automatically and synchronously (but in opposite phase) with the ventricular balloon by means of the control console, helium optionally being used as the inflating medium to ensure high speed inflation-deflation. |
