A bifurcated catheter, which can deploy a bifurcated stent constructed as a single piece into a bifurcated vessel, is disclosed. The system may have two main parts—a y-shaped catheter with a splittable seam, and a custom made stent, which can be deployed with the bifurcated catheter. The disclosed bifurcated catheter permits a physician or operator to stent a vessel at a bifurcation of the vessel.
