STENT WITH LATERAL OPENING

摘要

A stent (10) comprises a plurality of interconnected framework members defining a plurality of cells. A portion of the interconnected framework members comprise plurality of serpentine bands (20) which comprise connected turns (58) and unconnected turns (55), 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 (60) 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.
