Abstract
Coronary perfusion apparatus in which a catheter is held in place in the coronary artery by an intra-aortic balloon. The catheter carries a pressure sensor which is positioned adjacent the heart valves. The pump supplies oxygenation blood to the catheter at a predetermined time in the cardiac cycle which exists downstream of the occlusion through openings in the catheter under the control of a synchronizing means which determines the time of perfusion in response to cardiac signals and to signals corresponding to the measurement mode by the pressure sensor.
