Abstract:
1. A method of delivering a stent using a system, said system comprising a fixed wire catheter having a proximal end, a distal end and a first balloon disposed adjacent the distal end; a second catheter having a proximal end, a distal end and a second balloon adjacent the distal end; and a first expandable tubular member mounted on the fixed wire catheter and the second catheter, with said first tubular member having a proximal end forming a stem portion, a distal end forming a first leg portion, a longitudinal bore extending through the stem portion and the first leg portion, and a branch aperture disposed between the proximal end and the distal end, where the distal end of the second catheter extends from the proximal end of the first tubular member through the first leg portion and the distal end of the fixed wire catheter extends from the proximal end of the first tubular member through the branch aperture, the method comprising: a) delivering the first expandable tubular member, fixed wire balloon catheter and second balloon catheter to a bifurcated vessel having a first lumen and a second lumen; b) advancing the distal end of the fixed wire catheter into the second lumen; and c) inflating the first balloon sufficiently to align the branch aperture with the second lumen and to form a branch securing lip at the branch aperture of the first expandable tubular member.
