A stent in a non-expanded state, comprising:
a first expansion column including individual stair-step expansion struts forming a plurality of expansion strut pair loops that couple adjacent individual expansion struts, wherein two adjacent expansion strut pair loops share a common stair-step expansion strut;
a second expansion column including individual stair-step expansion struts forming a plurality of expansion strut pair loops that couple adjacent individual expansion struts, wherein two adjacent expansion strut pair loops share a common stair-step expansion strut;
and a first connecting strut column including a plurality of individual symmetrical geometry connecting struts, wherein each of an end of an individual connecting strut extends ipsilaterally from sides of expansion strut pair loops of the first and second expansion columns. |
