Ostial bifurcation lesion stenting catheter
First Claim
1. A stent deployment catheter having a distal end portion containing a forward facing abutment surface laterally offset from a proximal end of a forward extending stent carrier having a length sufficient for supporting and deploying a stent to treat an ostial bifurcation lesion, said stent deployment catheter further having an actuator for angularly displacing said distal end portion in a body vessel to align said abutment surface with a common vessel wall at the crux of a vessel bifurcation and align said stent carrier along the site of the ostial bifurcation lesion.

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.

11. A method for treating ostial bifurcation lesion, said method including the steps of:
-
advancing a stent laden carrier extending from a distal end portion of a catheter along a body vessel to a site of an ostial bifurcation lesion;
angularly displacing the stent laden carrier to orientate a stent carried thereby into a predetermined relation with the ostial bifurcation lesion established by concurrently bringing a forward facing abutment surface on the distal end portion of the catheter into a confronting relation with the crux of a vessel bifurcation at the site of the ostial bifurcation lesion; and
deploying the stent from the stent laden carrier. - View Dependent Claims (12, 13, 14, 15, 16)
