Displaceable stent side branch structure

A balloon expandable stent in an unexpanded configuration comprising:

• a plurality of struts arranged to form a substantially cylindrical expandable framework, the struts defining a plurality of cells;
• and
• a side branch structure comprising:
• an outer crown comprising a plurality of outer crown struts arranged to form a closed loop, the outer crown defining a side branch area;
• an inner crown comprising a plurality of inner crown struts and inner crown turns arranged to form a closed loop, the inner crown turns comprising inner turns and outer turns, the struts and inner turns defining petals, the inner crown defining an inner side branch cell having a shape different from the shape of any other cell, the inner turns located closer to a centerpoint of the inner side branch cell than the outer turns;
• and
• a plurality of side branch connectors made from the same material as the inner crown, each side branch connector having a first end connected to an outer turn of the inner crown and a second end connected to the outer crown, each side branch connector comprising an inflection point;
• wherein said plurality of side branch connectors comprises a first side branch connector having a length that is different from the length of a second side branch connector.
