Abstract[English]
In some variations, a circulatory assist system may include a pump body comprising a conduit having an inflow region and an outflow region, and a volume displacement member arranged in the conduit and operable between an expansion phase and a contraction phase. The circulatory assist system may also include an inlet valve arranged in the inflow region and comprising a plurality of leaflets. The inlet valve may receive blood into the conduit and the pump body may convey the received blood through the outflow region via cyclical operation of the volume displacement member between the expansion phase and the contraction phase. In some variations, the inlet valve may operate between open and closed states at high frequencies while withstanding a high pressure differential when the circulatory assist system is in use.[French]
Dans certaines variantes, un système d'assistance circulatoire peut comprendre un corps de pompe comprenant un conduit ayant une région d'entrée et une région de sortie, et un élément de déplacement de volume disposé dans le conduit et actionnable entre une phase d'expansion et une phase de contraction. Le système d'assistance circulatoire peut également comprendre une valve d'entrée disposée dans la région d'entrée et comprenant une pluralité de feuillets. La valve d'entrée peut recevoir du sang dans le conduit et le corps de pompe peut transporter le sang reçu à travers la région de sortie par l'intermédiaire d'un fonctionnement cyclique de l'élément de déplacement de volume entre la phase d'expansion et la phase de contraction. Dans certaines variantes, la valve d'entrée peut fonctionner entre des états ouvert et fermé à des fréquences élevées tout en résistant à un différentiel haute pression lorsque le système d'assistance circulatoire est en cours d'utilisation.
