Systems and methods for positioning a first guidewire ( 25 ) in a primary vessel (M) and a second guidewire ( 27 ) in a branch vessel (B). One embodiment comprises an introducer ( 10 ) having first ( 12 ) and second lumens ( 14 ) adapted to slidably receive the first guidewire within the first lumen and the second guidewire within the second lumen. One method embodiment includes inserting the first guidewire into the main vessel, introducing the introducer over the first guidewire, and inserting the second guidewire within the second lumen such that the second guidewire extends into the branch vessel. The introducer is withdrawn while maintaining the first and second guidewires in the respective vessels. |
