A tether guided bifurcated stent having a generally tubular main body extending along a longitudinal axis connected to a side branch assembly. Both the main stent body and the side branch assembly are capable of forming an unexpanded configuration and an expanded configuration. The bifurcations expansion is facilitated by a force exerted by the tether. When the side branch assembly is expanded it forms a secondary tubular region defining a generally tubular shape extending at an angle to the longitudinal axis of the main tubular body.
