An expandable dilation catheter advantageously useful to deliver and orient an endovascular prosthesis with respect to a target body passageway. The catheter comprises a first tubular member disposed in a proximal portion of the portion of the catheter and a second tubular member disposed in a distal portion of the catheter. The first tubular member and the second tubular member are in a spaced relationship with respect to one another. An expandable member (e.g., a ballon) is disposed distally of the second tubular member. A first lumen and a second lumen disposed in each of the first tubular member and in the second tubular member. The first lumen is in communication with an interior of the expandable member to function as an inflation lumen and the second lumen serves to receive a first guidewire. The first tubular member and second tubular member are interconnected by a coupling member.

L'invention porte sur un cathéter de dilatation extensible très utile pour amener et orienter une prothèse endovasculaire par rapport à un passage cible du corps. Ce cathéter comprend un premier élément tubulaire placé dans une section proximale d'une partie de celui-ci et un second élément tubulaire placé dans une partie distale de celui-ci. Le premier et le second élément tubulaire sont espacés l'un de l'autre. Un élément dilatable (tel qu'un ballonnet) est placé à l'écart du second élément tubulaire. Un premier et un second lumen sont placés dans le premier et le second élément tubulaire. Le premier lumen communique avec l'intérieur de l'élément extensible de façon à fonctionner comme un lumen de gonflage et le second lumen sert à accueillir un premier fil de guidage. Le premier et le second élément tubulaire sont interconnectés par un élément d'accouplement.
