Abstract:
A method of treating a lesion in a body at a bifurcation bifurcating a parent vessel into first and second branch vessels, the method comprising:providing a generally tubular member having a proximal end and a distal end and defining a guidewire lumen therein, the guidewire lumen sized to receive first and second guidewires, the generally tubular member having an elongate aperture extending from the distal end thereof proximally and being configured to engage a selected one of the first and second guidewires;loading the first and second guidewires into the guidewire lumen;advancing the first and second guidewires to the bifurcation such that a distal end of the first guidewire is in the first branch vessel and a distal end of the second guidewire is in the second branch vessel;advancing the generally tubular member to the bifurcation over the first and second guidewires;selecting the first guidewire; andadvancing the generally tubular member such that the elongate aperture is engaged with the first guidewire so the lumen tracks the second guidewire into the second branch vessel and so the first guidewire exits the guidewire lumen through the elongate aperture and remains in the first branch vessel.
