Devices and methods are provided for operating and controlling an interventional element on an interventional catheter. The interventional element may be a stent or series of stents, a balloon, or any other interventional element for which length control is necessary or desirable. A handle member includes an elongated body and an actuator knob that rotates around the longitudinal axis of the body. Rotational movement of the actuator knob is translated to rotational movement of one or more lead screws by a system of gears, rollers, or combinations of gears and rollers. Each of one or more axially moveable members is positioned on a lead screw and attached to a portion of the catheter shaft in order to provide the ability to advance or retract the portion of the cathether shaft.
L'invention porte sur des dispositifs et des méthodes d'utilisation et de commande de l'élément d'intervention d'un cathéter d'intervention. Ledit élément peut être un stent, une série de stents, un ballonnet, ou tout autre élément d'intervention dont il est nécessaire ou désirable de régler la longueur. L'invention porte également sur un manche comportant un élément allongé et un bouton de commande tournant autour de l'axe longitudinal du corps. La rotation du bouton de commande est transformée en rotation d'une ou de plusieurs vis mères par un système de pignons, de rouleaux ou de leur combinaison. Chacun des éléments tournants est placé sur une vis-mère et fixé en un point de la tige de cathéter de manière à permettre d'avancer ou de reculer la partie de la tige du cathéter.
