Abrégé
(EN)
A radially expandable prosthetic valve can comprise an annular frame, at least one expansion mechanism and a cord. The annular frame can be radially collapsible and expandable between a radially collapsed configuration and a radially expanded configuration. The expansion mechanism can comprise a first member attached to the frame at a first location and a second member attached to the frame at a second location axially spaced from the first location. The cord can extend at least partially along the expansion mechanism in a first direction, be reeved around a portion of the second member, and extend at least partially along the expansion mechanism in a second direction opposite the first direction. Applying a proximally directed force to a first portion of the cord can cause the second member to move relative to the first member, which can cause the frame to foreshorten axially and expand radially.

La présente invention concerne une valvule prothétique radialement extensible pouvant comprendre un cadre annulaire, au moins un mécanisme d'expansion et un cordon. Le cadre annulaire peut être radialement compressible et expansible entre une configuration radialement comprimée et une configuration radialement expansée. Le mécanisme d'expansion peut comprendre un premier élément fixé au cadre à un premier emplacement et un second élément fixé au cadre à un second emplacement disposé axialement à distance du premier emplacement. Le cordon peut s'étendre au moins partiellement le long du mécanisme d'expansion dans une première direction, être enroulé autour d'une partie du second élément, et s'étendre au moins partiellement le long du mécanisme d'expansion dans une seconde direction opposée à la première direction. L'application d'une force dirigée de manière proximale sur une première partie du cordon peut amener le second élément à se déplacer par rapport au premier élément, ce qui peut amener le cadre à se raccourcir axialement et à se déployer radialement.
