Abstract:
1. A method of placing multiple stents side-by-side across a single stricture along an unbifurcated length of duct, the method comprising steps of: directing only a single stent-placement catheter to a location adjacent a stricture along an unbifurcated length of duct to be stent-traversed; directing only a single wire guide through a wire guide lumen encompassed by at least a lengthwise portion of the stent-placement catheter and through the stricture; directing a distal end length of the stent-placement catheter through the stricture; directing a first stent through a lengthwise stent lumen of the stent-placement catheter portion disposed within the stricture and alongside the wire guide, where first stent is advanced distally by a stent pusher and where the wire guide is unencompassed by any portion of the first stent; moving the stent-placement catheter in a manner that leaves the first stent and the wire guide in place across the stricture; and with the wire guide remaining disposed through the stricture and the stent-placement catheter remaining disposed within or immediately adjacent the stricture, directing a second stent through the stent lumen and through the stricture alongside the wire guide and at least partially alongside, and wholly external of, the first stent, where the second stent is advanced distally by the stent pusher and where the wire guide and the first stent are unencompassed by any portion of the second stent.
