BIFURCATED CATHETER ASSEMBLY

摘要

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 pai r 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. T he bifurcated catheter assembly can be used to dilate a stenosis or deliver and implant a Y-shaped stent in the bifurcation.
