| abstract |
A trifurcated stent apparatus for use by a physician includes a main stent for inserting into a trifurcated blood vessel and two side stents. The main stent includes two openings on the side which are the same diameter as the corresponding side stents. The main stent may be configured to receive a first end of a first side stent and a first end of a second side stent, to create a trifurcated stent. Alternatively, the side stents and the main stent may form a single integrated unit. The main stent and side stents can include one-way valves on one or more of the ends. The one or more one-way valves 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. |
