Abstract
In at least one other 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 first serpentine ring, a second serpentine ring and a plurality of side branch connectors. The first serpentine ring extends around the inner side branch cell and comprises alternating inner turns and outer turns. The second serpentine ring extends around the first serpentine ring and comprises alternating inner turns and outer turns. The second serpentine ring has the same number of outer turns as the first serpentine ring. Each side branch connector spans between the first serpentine ring and the second serpentine ring in a side branch radial direction.
