ABSTRACT:
An apparatus and method for treating congenital heart defects, such as cyanotic heart defects which includes a shunt implanted within a patient's cavity for communicating blood from the patient's arterial system to the patient's pulmonary system. An adjustable flow restrictor forms part of the shunt and is operative to adjust the effect of cross-section of the shunt thereby varying the blood flow rate in the shunt. An oximeter monitors the oxygen saturation levels in the blood and in cooperation with a restrictor control varies inflation of the bladder to maintain an oxygen saturation level in the blood between predetermined limits.
