Abstract
A device and method for assisting the pumping action of a failed heart. The device comprises an inelastic balloon, preferably conical in shape, connected to a catheter and pump. The balloon is percutaneously fed into a major blood vessel and then guided to a ventricle of the heart. When placed in the left ventricle, the balloon inflates during the isovolumetric contraction period before the aortic valve opens, and deflates after the aortic valve is closed but before the mitral valve has opened.
