The bifurcated stent apparatus for use by a physician includes a main stent for inserting into a bifurcated blood vessel and a side stent. The main stent has an opening on the side which is the same diameter as the side stent. The main stent may be is configured to receive a first end of the side stent, to create a bifurcated stent. Alternatively, the side stent and the main stent may form a single integrated unit. The side stent includes a one-way valve on the second end. The one-way valve may be opened or closed, depending on whether the physician desires that fluid pass through. While closed, the valve may be configured to allow passage of various cardiovascular instruments, including but not limited to guidewires, catheters, balloons, or any other device used in blood vessel operations, while not allowing the passage of any fluids.
