Abstract[English]
Systems and methods for generating blood flow with a blood pump including a membrane and an encapsulated actuator are described. The pump may be implantable and may include a stator assembly, an electromagnetic assembly supported by the stator assembly, a magnetic assembly, one or more springs attached to the stator and the magnetic assembly, and encapsulation portions that connect the magnetic assembly to the stator assembly. The magnetic assembly may further be coupled to a membrane assembly including a flexible membrane. The electromagnetic assembly may be selectively activated to cause the magnetic assembly to reciprocate, thereby causing the membrane assembly to reciprocate and inducing wavelike undulations in the flexible membrane to pump blood from an inlet to an outlet of the pump. The encapsulation portions may prevent blood from interacting with an interior moving portion of the pump thereby reducing the risk of hemolysis.[French]
L'invention concerne des systèmes et des procédés pour générer un flux sanguin au moyen d'une pompe à sang comprenant une membrane et un actionneur encapsulé. La pompe peut être implantable et peut comprendre un ensemble stator, un ensemble électromagnétique supporté par l'ensemble stator, un ensemble magnétique, un ou plusieurs ressorts fixés au stator et à l'ensemble magnétique, et des parties d'encapsulation qui relient l'ensemble magnétique à l'ensemble stator. L'ensemble magnétique peut en outre être accouplé à un ensemble membrane comprenant une membrane souple. L'ensemble électromagnétique peut être sélectivement activé pour amener l'ensemble magnétique à effectuer un mouvement de va-et-vient, amenant ainsi l'ensemble membrane à effectuer un mouvement de va-et-vient et à induire des ondulations en forme d'onde dans la membrane souple pour pomper le sang depuis une entrée vers une sortie de la pompe. Les parties d'encapsulation peuvent empêcher le sang d'interagir avec une partie mobile intérieure de la pompe, réduisant ainsi le risque d'hémolyse.
