Abstract : Fluid amplification, a recent Army invention concerned with the control of flowing fluids without moving parts, was applied to the powering and control of an extracorporeal heart pump. Except for an artificial ventricle and two artificial heart valves the fluid amplifier pump has neither moving control parts nor electronics. The output is pulsatile and its average rate of flow varies directly with filling pressure and inversely with vascular and other resistances, to achieve flow regulation. Atrial contraction and venticular fibrillation, a type of heart failure, can be simulated. Because of the design, high reliability, long life and low cost are achieved. Early evaluation tests suggest its performance capabilities and hemolytic characteristics are at least equal to those of the better available heart pumps. (Author)
