Abstract
A stent delivery catheter system for accurately positioning a stent in a bifurcated vessel is disclosed. The system includes a catheter having a terminal portion and distal tip that is placed in a main branch of the vessel proximate the bifurcation. A fixed guidewire is attached to distal tip. A port is defined in the terminal portion of the catheter. The port is aligned with an ostium of a side branch of the bifurcated vessel to allow the passage of a stent delivery device, such as a balloon catheter having a stent crimped thereon, into the side branch. Radiopaque bands are positioned on opposite ends of the port. A positioning balloon is included on a surface of the catheter opposite the port and is selectively inflatable to position the radiopaque bands adjacent the side branch ostium. The radiopaque bands are referenced to place the stent proximate the side branch ostium.
