1. A stent in a non-expanded state, comprising:

  • a first expansion column including individual first expansion struts forming a plurality of first expansion strut pairs, at least a portion of each first expansion strut having a stair-step region, two adjacent first expansion strut pairs share a common strut;

    a second expansion column including individual second expansion struts forming a plurality of second expansion strut pairs, at least a portion of each second expansion strut having a stair-step region, two adjacent second expansion strut pairs share a common strut;

    a first connecting strut column including a plurality of non-intersecting individual first connecting struts that couple only the first and second expansion columns, wherein each of an individual first connecting strut includes a proximal section and a distal section, at least a portion of the proximal section of each first connecting strut extending from a portion of the stair-step region of one of the first expansion struts, at least a portion of the distal section of each first connecting strut extending from a portion of the stair-step region of one of the second expansion struts, each proximal section having a longitudinal axis and each distal section having a longitudinal axis, at least one of the longitudinal axis of each proximal section and the longitudinal axis of the distal section being parallel with at least one of a longitudinal axis of each first expansion strut and a longitudinal axis of each second expansion strut.
