HEART ASSISTANCE OR BACK-UP DEVICE

Abstract

A device for the temporary circulatory assistance or back-up of the heart of a patient including: a linear actuator configured to move a membrane in a chamber so as to cause a pulsating fluid flow adapted to support the activity of the heart of the patient, which flow is characterised by a succession of phases of aspiration and phases of ejection of the fluid, a control unit configured to pilot the actuator and control the movement of the membrane, which piloting is carried out while taking into account input data originating from an ECG signal of the patient, the control unit is configured to determine a time offset between the instant at which the QRS complex of the ECG signal is detected and the instant at which an ejection phase is initiated.
