1. A bifurcated stent being expandable from an unexpanded state to an expanded state, wherein in the unexpanded state the stent has a diameter less than that of the diameter in the expanded state, the bifurcated stent comprising:

  • a substantially tubular first stent body defining a first circumferential plane, a first outer surface, a first lumen and having a proximal end, a distal end, a first longitudinal axis extending therethrough, and having a side opening along the first circumferential plane;

    a second stent body positioned adjacent to the side opening and engaged to first stent body, the second stent body comprising a plurality of interconnected expandable rings at least two of the rings having progressively differing widths, in the unexpanded state the at least two rings being positioned substantially within the first circumferential plane, in the expanded state the at least two rings being positioned external to the first circumferential plane and defining a secondary circumferential plane, a secondary lumen, and having a secondary longitudinal axis extending therethrough, the secondary lumen being in fluid communication with the first lumen, the secondary longitudinal axis forming an oblique angle with the primary longitudinal axis.
