Abstract
In at least one embodiment, a stent comprises a plurality of interconnected framework members defining a plurality of cells. A portion of the interconnected framework members comprise a side branch structure defining an inner side branch cell that is shaped differently from other cells of the stent. The side branch structure comprises a serpentine ring that extends around the inner side branch cell. The serpentine ring comprises alternating struts and turns. The turns comprise alternating inner turns and outer turns, and the inner turns comprise alternating first inner turns and second inner turns. The second inner turns are located farther away from a side branch center point than the first inner turns.
