Abstract
Devices and methods for treating bifurcated body vessels, including stenosed, bifurcated coronary arteries. Methods can include advancing a guide catheter to the stenosed bifurcated region, advancing first and second guide wires through the guide catheter into separate vessel regions past the bifurcation, and then withdrawing the guide catheter. The method proceeds by advancing a balloon catheter having a bifurcated stent mounted to a Y-shaped distal balloon region over the guide wires, and positioning the bifurcated stent proximal of and distal to the bifurcation. Inflating the balloons dilates the stenosed region and expands the bifurcated stent. Kits provided by the present invention can include two guide wires, a guide catheter, a balloon catheter having a Y-shaped distal balloon region, and a bifurcated stent configured to be carried over the distal balloon region.
