Abstract

A stent deploying catheter and method for placing a stent in a branching anatomic duct commencing at the ostium includes a distal portion containing a forward facing abutment surface laterally offset from a proximal end of a forward extending stent carrier. The forward facing abutment surface overlies the radio opaque marker to aid in the orientation and placement of the stent. The forwarding extending stent carrier in one embodiment includes a catheter balloon and having a length sufficient for supporting and deploying a stent to treat an ostial bifurcation lesion. The stent carrier in another embodiment includes a sheathing which can be retracted for deploying a self-expanding stent. An actuator wire extends along the catheter for angularly displacing the distal end portion in a body vessel to align the abutment surface with a common vessel wall at the crux of a vessel bifurcation and align the stent carrier along the site of the ostial bifurcation lesion. A guide wire lumen is also provided for the introduction and guiding of the distal end portion along the vessel.
