A bifurcated stent that uses turning segments to reduce the strain at regions which bend at extreme angles. The turning segments can be placed on side branch petals or on connectors connecting the petals to the stent body. Combining the turning segments with connectors of different length and tethers provides for a stent with high flexibility that can accommodate various shaped body vessels. This design allows the bifurcation branch to extend easily, to a useful distance, and to be deployed along oblique angles. Best of all, this design avoids the problems of angularly strained side branch.

A catheter assembly includes a main catheter branch and a side catheter branch. The main catheter branch includes first and second balloons. The side catheter branch is coupled to the second balloon. The side catheter branch can be coupled to the second balloon portion by passing through a pathway or receiver structure defined in the second balloon. The side catheter branch can also be coupled to the second balloon portion using a connector that connects the side catheter branch to a portion of the main catheter branch that carries the second balloon portion.
