Patent ID: 8771342

Claim:
A method of deploying a stent in a bifurcation of a main vessel which separates into first and second branch vessels, the method comprising: first, inserting a first guidewire into the main vessel such that the first guidewire extends across the bifurcation and into the first branch vessel; providing a stent delivery device including a main lumen for receiving the first guidewire, a branch lumen for receiving a second guidewire, and an expandable stent disposed thereon; after inserting the first guidewire into the main vessel, inserting the second guidewire into the branch lumen of the stent delivery device such that a distal end of the second guidewire is adjacent to a distal end of the branch lumen; after the second guidewire is inserted into the branch lumen, advancing the stent delivery device over the first guidewire through the main vessel to a position adjacent to the bifurcation; without retracting the second guidewire, advancing the second guidewire through the distal end of the branch lumen and into the second branch vessel; advancing the stent delivery device over the first guidewire and the second guidewire to a stent deployment position adjacent the bifurcation; and radially expanding the stent with at least a proximal end of the stent extending into the main vessel.
