Abstract

The invention relates to a method of automatic control of a motor of a peristaltic cardiac prosthesis, characterised in that it comprises the following steps: - during an ejection phase, applying to the motor a current which causes its rotation in a first sense at an essentially constant speed, and - during a return phase, applying to the motor a current which causes its rotation in the opposite sense at a speed which varies according to a monotonic law with the value of a parameter obtained from the average current flowing in the motor and representing the average force provided by the motor. The invention also relates to a device implementing the method. <IMAGE>
