Title
(EN) VALVE DELIVERY SYSTEM
(FR) SYSTÈME DE POSE DE VALVULE
Abstract
(EN) Delivery systems and methods for delivering a valve anchor and a valve prosthesis to a native valve annulus are provided. The anchor can be deployed near the native valve annulus with a tether attached thereto. A portion of the tether can be positioned inferior to the deployed anchor in an inverted configuration for advantageous positioning for adjusting the anchor position and/or deployment of the valve prosthesis. A positioning tool can be tracked over the tether and used to properly position the anchor. The positioning tool can be configured to transition to a stiffened state that includes one or more bends configured to allow efficient positioning of the deployed anchor and to provide room for deploying the valve prosthesis. Once the anchor is properly positioned, the valve prosthesis can be deployed within the native valve annulus and within the valve anchor.
(FR) L'invention concerne des systèmes de pose et des procédés permettant de poser un ancrage de valvule et une prothèse de valvule sur un anneau de valvule native. L'ancrage peut être déployé à proximité de l'anneau de valvule native avec un amarre fixé à celui-ci. Une partie de l'amarre peut être positionnée sous l'ancrage déployé selon une configuration inversée pour un positionnement avantageux pour ajuster la position d'ancrage et/ou le déploiement de la prothèse de valvule. Un outil de positionnement peut être suivi sur l'amarre et utilisé pour positionner correctement l'ancrage. L'outil de positionnement peut être conçu pour passer à un état rigidifié qui comprend un ou plusieurs coudes conçus pour permettre un positionnement efficace de l'ancrage déployé et pour fournir de l'espace en vue de déployer la prothèse de valvule. Une fois que l'ancrage est correctement positionné, la prothèse de valvule peut être déployée à l'intérieur de l'anneau de valvule native et à l'intérieur de l'ancrage de valvule.
