    • In some embodiment, a stent comprises a plurality of interconnected framework members defining a plurality of cells. A portion of the interconnected framework members comprise plurality of serpentine bands which comprise connected turns and unconnected turns, wherein at least one of the serpentine bands comprises a repeating pattern of three band struts and then five band struts extending between connected turns as the serpentine band is traversed. A portion of the interconnected framework members comprise a side branch structure defining an inner side branch cell that is shaped differently than other cells of the stent. The side branch structure includes a serpentine ring that comprises alternating struts and turns. The turns comprise alternating inner turns and outer turns. The inner turns comprise alternating first inner turns and second inner turns, wherein the second inner turns are located farther away from a side branch center point than the first inner turns.
