Title (EN) BICUSPID VALVE DISSECTION DEVICE
(FR) DISPOSITIF DE DISSECTION DE VALVE BICUSPIDE
Abstract:
(EN) The invention is a device, system, and method for repairing heart valve function, which may include bisecting native valve leaflets for improved deployment of a prosthetic heart valve in the native valve annulus. The invention may include a catheter having a cutting element shaft with a cutting element configured to puncture a valve leaflet and/or make a controlled cut through the leaflet. The device may have an extendable foot configured to be positioned on an opposite side of the valve leaflet from the cutting element shaft. The device may include magnets to guide the cutting element and/or cutting element shaft in proper alignment with the extendable foot and to hold the elements in place during leaflet bisection.
(FR) La présente invention concerne un dispositif, un système, et un procédé de réparation d’une fonction de valve cardiaque, qui peut consister à couper en deux des feuillets valvulaires natifs en vue du déploiement amélioré d’une valve cardiaque prothétique dans l’anneau de valve native. L’invention peut comprendre un cathéter ayant une tige d’élément de coupe et un élément de coupe conçu pour perforer un feuillet valvulaire et/ou pour réaliser une découpe commandée à travers le feuillet. Le dispositif peut présenter un pied extensible conçu pour être positionné sur un côté opposé du feuillet valvulaire depuis la tige d’élément de coupe. Le dispositif peut comprendre des aimants pour guider l’élément de coupe et/ou la tige d’élément de coupe de manière à obtenir un alignement approprié avec le pied extensible, et pour maintenir les éléments en place pendant que le feuillet est coupé en deux.
