Claim 10:
11. A method of controlling a continuous-flow ventricular assist device, the method comprising:
generating, by a sensor, a signal indicative of indicative of a power consumption of a continuous-flow ventricular assist device comprising a centrifugal rotor configured to generate a centrifugal flow, wherein the continuous-flow ventricular assist device receives blood from a ventricle of a heart of a patient and pumps the blood to an aorta of the patient to assist blood flow from the ventricle to the aorta;
detecting, by a controller based on a speed of the continuous-flow ventricular assist device and the power consumption of the continuous-flow ventricular assist device, contractions of the ventricle; and
controlling, by the controller, the speed of the continuous-flow ventricular assist device to operate in an artificial pulse mode that produces a pulsatile blood flow, wherein the artificial pulse mode comprises recurring changes in a rotational speed of the continuous-flow ventricular assist device, and wherein at least one of the recurring changes in the rotational speed of the continuous-flow ventricular assist device are synchronized with the contractions of the ventricle.
