Title
(EN) PROSTHETIC VALVE DELIVERY ASSEMBLY
(FR) ENSEMBLE DE POSE DE VALVULE PROTHÉTIQUE
Abstract
(EN)
A prosthetic valve delivery assembly is disclosed. The assembly includes a delivery apparatus having a shaft and a prosthetic valve mounted in a radially compressed configuration around a distal portion of the shaft. The delivery apparatus further includes an expansion assist device mounted on the shaft. The expansion assist device is independently radially expandable and compressible relative to the prosthetic valve between a radially compressed state and a radially expanded state. The prosthetic valve is radially expandable by apply ing an axially directed force against the prosthetic valve in a proximal or distal direction through contact between the prosthetic valve and the expansion assist device when the expansion assist device is in the radially expanded state.
(FR)
L'invention concerne un ensemble de pose de valvule prothétique. L'ensemble comprend un appareil de pose ayant un arbre et une valvule prothétique montée dans une configuration radialement comprimée autour d'une partie distale de l'arbre. L'appareil de pose comprend en outre un dispositif d'assistance à l'expansion monté sur l'arbre. Le dispositif d'assistance à l'expansion est indépendamment expansible et compressible radialement par rapport à la valvule prothétique entre un état radialement comprimé et un état radialement étendu. La valvule prothétique est radialement extensible en appliquant une force dirigée axialement contre la valvule prothétique dans une direction proximale ou distale par contact entre la valvule prothétique et le dispositif d'assistance à l'expansion lorsque le dispositif d'assistance à l'expansion est dans l'état déployé radialement.
