Bifurcation stent and balloon assemblies

A bifurcated stent that is positionable adjacent to a branched body vessel. The stent includes a tapered middle portion with a side branch assembly for positioning within the deviating branch of a body vessel. The portion of the stent positioned within the first body vessel and the portion positioned within the main branch vessel have largely different sized diameters. The middle region tapers steeply to bridge this diameter differential. The tapered middle region also angles the side branch assembly which can easily be extended at an angle to the main body of the stent.
