<p>A stent (10) in a non-expanded state, comprising: a first expansion column (33) including individual expansion struts (60,62) forming a plurality of expansion strut pair loops that couple adjacent individual expansion struts, wherein two adjacent expansion struts share a common strut; a second expansion column (34) including individual expansion struts forming a plurality of expansion strut pair loops that couple adjacent individual expansion struts, wherein two adjacent expansion struts share a common strut; and a first connecting strut column (37) including a plurality of individual connecting struts (36), wherein each of an individual first connecting strut has a stair-step geometric configuration with first and second intermediate sections, a proximal segment coupled to the first expansion column and a distal segment conjoined directly to an expansion strut of the second expansion column.</p> |
