First Claim
Patent Images
1. A device for implanting a body vessel in the region of a vessel branching, comprising a radially expandable stent formed as a hollow cylindrical element and provided with an increased radial opening;
- and a balloon catheter on which said stent is premounted for implanting in the vessel, said balloon catheter having a hollow chamber for passage of a guiding wire so that it exits in a center of said increased opening from said hollow chamber and said stent, said balloon catheter being provided with another longitudinal chamber extending along a longitudinal axis of said catheter and formed so that a further guiding wire extends through said other longitudinal chamber and exits at a tip of said balloon catheter.
