1. A stent, the stent comprising:
- a first section, the first section comprising a first circumferential ring, the first circumferential ring consisting a plurality of first end struts, each first end strut having a first end length where the first end length is the same for each first end strut;
a second section, the second section comprising a first circumferential ring, the first circumferential ring comprising a plurality of transitional struts, the plurality of transitional struts comprising a first transitional strut and a second transitional strut, the first transitional strut having a first transitional length, the second transitional strut having a second transitional length;
a plurality of first connectors, the plurality of first connectors engaging the first section and the second section, the plurality of first connectors being substantially circumferentially aligned when the stent is in an unexpanded state; and
a third section, the third section comprising a first circumferential ring having a circumferential length, the first circumferential ring comprising a plurality of middle struts, the plurality of middle struts comprising a first middle strut, a second middle strut and a third middle strut, the first middle strut having a first middle length, the second middle strut having a second middle length and the third middle strut having a third middle length, the first middle length, the second middle length and the third middle length being different lengths,wherein the first middle strut, the second middle strut, and the third middle strut are arranged in a middle pattern, the middle pattern repeating about the entire circumferential length of the first circumferential ring.
