Title (EN) STENTED VALVE
(FR) VALVULE À STENT
Abstract:
(EN) A stented valve suitable for use in body ducts. The valve includes an expandable support structure and an attached flexible membrane that changes shape when the valve opens and closes. The expandable support structure has the shape of a stent with a series of interconnected expandable unit cells and elongated support beams. When the valve is open, body fluid can flow around the membrane and pass through the gap between it and the inner stent surface. In one configuration, a set of two valves is combined with an intermediate inflatable balloon to create a cardiac assist pumping device. In another embodiment, valve closure can be achieved by remotely controlled valve leaflets actuation. A double aorta valve frame is used to accommodate shape and diameter variations of the annulus in an outer valve frame, while the inner valve frame has dimensions for optimized performance of the valve membrane.
(FR) L'invention concerne une valvule à stent appropriée pour être utilisée dans des conduits corporels. La valvule comprend une structure de support extensible et une membrane flexible attachée qui change de forme lorsque la valvule s'ouvre et se ferme. La structure de support extensible présente la forme d'un stent avec une série de cellules unitaires extensibles et d'entretoises de support allongées interconnectées. Lorsque la valvule est ouverte, le fluide corporel peut s'écouler autour de la membrane et passer à travers l'espace entre celle-ci et la surface de stent interne. Dans une configuration, un ensemble de deux valvules est associé à un ballonnet gonflable intermédiaire en vue de créer un dispositif de pompage d'assistance cardiaque. Dans un autre mode de réalisation, la fermeture de valvule peut être obtenue par actionnement de valvules commandé à distance. Un cadre de valvule à double aorte est utilisé pour recevoir des variations de forme et de diamètre de l'anneau dans un cadre de valvule externe, tandis que le cadre de valvule interne a des dimensions pour une performance optimisée de la membrane de valvule.
