A catheter system for inserting a first guidewire in a primary vessel and a second guidewire in a branch vessel, comprising: a dual lumen catheter having a first guidewire slidably received within a first lumen; and a side sheath received within a second lumen; and a second guidewire slidably received within a lumen of the side sheath. n A method of aligning a side opening in a primary stent in registry with the ostium of a branch vessel, comprising: advancing a first guidewire through a primary vessel such that a distal end of a guidewire extends past an intersection of the primary vessel and the branch vessel; advancing the primary stent over the first guidewire with a dual lumen catheter, the dual lumen catheter having a side sheath received through a second lumen, and a first guidewire received through a first lumen; advancing the side sheath through the second lumen of the dual lumen catheter such that a distal end of the side sheath is positioned at the intersection of the primary vessel and the branch vessel; and advancing a second guidewire through the side sheath and out through the side opening in the primary stent and into the branch vessel, thereby aligning the side opening in the primary stent with the ostium of the branch vessel. |
