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.

Abstract
Various intravascular stents, such as intracoronary stents, include improved expansion and connecting strut designs. Such stents can be both very flexible and fully cover vessel surface inside the vascular lumen, and be well designed for both the delivery phase and the deployed phase of the stent life cycle.
