| 摘要 |
<p>The invention concerns a ventricular cardiac aid device with counter-pulsation, comprising the following implanted elements: an aortic sleeve (1) placed on the ascending aorta (10) and capable of producing a counter-pulsation on the blood in the aorta by the effect of an intermediate fluid flowing into the sleeve; an electrohydraulic actuator (2) acting upon the intermediate fluid for producing said counter-pulsation; a compliance chamber (3) for accommodating the variation in volume of the intermediate fluid when the actuator (2) is operating; electric supply means for powering the electrohydraulic actuator (2).</p> |
