Patent ID: 7591846

Claim:
A method of deploying a stent in a bifurcation of a main vessel which separates into first and second branch vessels, said stent including a proximal end to be deployed in said main vessel on the proximal side of said bifurcation, and a distal end to be deployed in said first branch vessel on the distal side of said bifurcation, the method comprising: introducing the distal end of a first guidewire through said main vessel and said bifurcation into said first branch vessel; introducing the distal end of a second guidewire through said main vessel and said bifurcation into said first branch vessel; providing a stent delivery device including a main lumen for receiving said first guidewire, a branch lumen for receiving said second guidewire, and an expandable stent; inserting the proximal end of said first guidewire into a distal end of said main lumen of said stent delivery device; inserting the proximal end of said second guidewire into a distal end of said branch lumen of said stent delivery device; guiding said stent delivery device along said first guidewire and said second guidewire through said main vessel to an initial position adjacent to the proximal side of said bifurcation; retracting the distal end of said second guidewire; advancing said second guidewire into said second branch vessel; advancing said stent delivery device, while tracked by said first guidewire in said first branch vessel, and by said second guidewire in said second branch vessel, to said predetermined deployment position with respect to said bifurcation, to bring said distal end of said stent into said first branch vessel, while the proximal end of said stent still remains in said main vessel; radially expanding said stent; and removing said stent delivery device.
