This short communication describes a cardiac bypass pump which produces a pulsatile flow. By driving a roller pump with a dc torque motor, it has been possible to provide electronic control of pulse rate and stroke volume. Flow and pressure recordings in dogs undergoing left-heart bypass are nearly physiological.
