A bifurcated stent has an expanded and an unexpanded state with an outer surface and an inner surface with a wall extending there between and the inner surface defining an inner stent lumen. The stent has a primary stent body with a proximal end and a distal end with a band circumferential there between. A side branch portion is disposed in the band circumferential and in the unexpanded state the band circumferential has at least one overlapped section such that the at least one overlapped section has a greater density of stent material than the rest of the stent. In the expanded state the side branch portion extends obliquely from the primary stent body. |
