A synchronous, pulsatile angioplasty system utilizes a control apparatus which controls balloon inflation and deflation in a pulsatile fashion synchronized with the heartbeat of a patient. A heart monitor provides an input, a signal to the control apparatus which serves as a baseline for operation of the pulsatile inflation and deflation of the balloon. A triggering circuit reads the baseline signal and generates a control signal to selectively generate valves interconnecting the angioplasty catheter with sources of inflation media and low pressure. Time delay circuits may be utilized which delay either the duration of the control signal or the receipt thereof by the control valves.
