An apparatus and method is provided for stenting bifurcated vessels. A proximal angled stent is configured for implanting in a side-branch vessel wherein the proximal angled stent has an angulated portion that corresponds to the angle formed by the intersection of the side-branch vessel and the main vessel so that all portions of the side-branch vessel at the bifurcation are covered by the proximal angled stent. A main-vessel stent is provided for implanting in the main vessel, wherein the main-vessel stent has an aperture or stent cell that aligns with the opening to the side-branch vessel to permit unobstructed blood flow between the main vessel and the side-branch vessel. Side-branch and main-vessel catheter assemblies are advanced over a pair of guide wires for delivering, appropriately orienting, and implanting the proximal angled stent and the apertured stent.

[ What is claimed is:] [1.]1. A stent delivery catheter assembly for treating bifurcated vessels having a side-branch vessel and a main vessel, comprising:a dual balloon Y-shaped catheter having a proximal end and a distal end, the catheter including a first expandable member having a proximal end and a distal end, the catheter further including a second expandable member having a proximal end and a distal end;a first guide wire lumen for receiving a first guide wire, the first guide wire lumen extending through at least a portion of the catheter including the first expandable member;a second guide wire lumen for receiving a second guide wire, the second guide wire lumen extending through at least a portion of the catheter including the second expandable member; anda Y-shaped stent;wherein the first expandable member and the second expandable member are normally biased apart, but are restrained and held together to provide a low profile during delivery of the Y-shaped stent.
