A bifurcated catheter assembly is provided for treating bifurcated vessels. The bifurcated catheter assembly comprises an elongate main catheter shaft having a stiffer proximal portion, a more flexible distal portion, and a pair of branch catheters attached to the distal portion. An expandable member is located on each of the branch catheters. The balloons are held together to provide a low profile as the device is advanced over the tracking guide wire. Upon reaching the bifurcated vessel, the balloons separated and are advanced over separate guide wires into separate branches of the bifurcated vessel. The bifurcated catheter assembly can be used to dilate a stenosis or deliver and implant a Y-shaped stent in the bifurcation.
La présente invention concerne un ensemble cathéter à fourche conçu pour des interventions sur des vaisseaux à bifurcation. Cet ensemble cathéter comprend une tige principale de cathéter plus rigide dans sa partie proximale, plus flexible dans sa partie distale, laquelle partie distale est solidaire d'une paire de cathéters en fourche. Chacun des cathéters de la fourche comporte un élément extensible. Les ballonnets sont maintenus l'un à l'autre afin de ne présenter qu'un encombrement réduit pendant la progression du dispositif le long du fil de guidage. Une fois atteint le point de bifurcation du vaisseau, les ballonnets se séparent et continuent de progresser le long de fils de guidage distincts dans chacune des branches du vaisseau. Cet ensemble cathéter à fourche convient pour la dilatation d'une sténose ou la mise en place d'un stent en forme de Y dans une bifurcation.
