Abstract
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.
