• A simple circulatory device to substitute sufficiently the total cardiac functions was tried. Double valved cannulae were inserted via the right and left ventricular walls to the pulmonary artery and the aorta and con-nected to pulse pressure generators. The pump accepted blood through the inflow valve in the ventricle during negative pressure phase and ejected to the artery through the outflow valve during positive pressure phase. Over 20 dogs experiments showed that this complete cardiac bypass method could maintain the left and right atrial pressures, the pulmonary and systemic arterial pressures and cardiac output at physiological condi-tions under ventricular fibrillation. The results of long-term pumping in 10 dogs were over 20 hours pumping in 5 dogs, over 30 hours in 3 dogs and the maximum pumping term was 46 hours.
