Abstract:
A stent delivery assembly for treating bifurcated vessels having a side-branch vessel and a main vessel, comprising:a side-branch catheter having a proximal end and a distal end;an expandable member proximate the distal end of the catheter;a tracking guide wire lumen extending within at least a portion of the side-branch catheter;a tracking guide wire having a distal end and a proximal end and sized for slidable movement within the tracking guide wire lumen;a positioning guide wire lumen associated with the expandable member wherein at least a portion of the positioning guide wire lumen is external to the catheter;a positioning guide wire having a distal end and a proximal end and sized for slidable movement within the positioning guide wire lumen;the proximal ends of the tracking and position guide wires extend out of the patient and can be manipulated so that the distal end of the position guide wire is advanced in the main vessel distal to the side-branch vessel, and the distal end of the tracking guide wire is advanced into the side-branch vessel.
