Patent ID: 8029555

Claim:
A method for propping open a narrowed bifurcated anatomy having a main lumen and first and second branch lumens, the method comprising the steps of: a) providing a stent delivery system comprising; a first introducer comprising: a first tubular body having a first proximal portion, a first distal portion, a first stent carrying portion therebetween, and a first stent; a second introducer comprising: a second tubular body having a second proximal portion, a second distal portion, a second stent carrying portion therebetween and a second stent; a catheter for receiving the second introducer, the catheter having a frangible wall; a first wire guide; and a second wire guide; b) positioning the first introducer and the catheter in a working channel of an endoscope in a staggered configuration; c) positioning the endoscope adjacent the bifurcated anatomy; d) advancing the first wire guide through the working channel to the first branch lumen; e) advancing the second wire guide through the working channel to the second branch lumen, independent of the first introducer ; f) advancing the first introducer over the first wire guide to the first branch lumen of the bifurcation; g) advancing the catheter over the second wire guide to the second branch lumen of the of the bifurcation; and h) deploying the first stent within the first branch lumen and the main lumen; i) advancing the second introducer over the wire guide and through the catheter to the second branch lumen wherein advancing the second introducer through the catheter splits the catheter along the frangible wall; j) removing the catheter; k) deploying the second stent; and l) withdrawing the second introducer.
