A stent with a longitudinal axis comprising:
a plurality of interconnected fir expansion strut pairs forming a first expansion column, each first expansion strut pair having
a first straight expansion strut having a distal end and a proximal end,
a second expansion strut having a distal end, a proximal end and a step-down notch,
€ƒ€ƒ€ƒand a first joining strut coupling the distal end of the first expansion strut of the first expansion strut pair to the distal end of the second expansion strut of the first expansion strut pair;
a plurality of interconnected second expansion strut pairs forming a second expansion column adjacent to the first expansion column, each second expansion strut pair having
a first straight expansion strut having a distal end and proximal end,
a second expansion strut having a distal end and proximal end and a step-down notch,
€ƒ€ƒ€ƒa second joining strut coupling a distal end of the first expansion strut of the second expansion strut pair to the distal end of the second expansion strut of the second expansion strut pair; and
a first serial connecting strut column formed of a plurality of serial connecting struts coupling the first expansion column to the second expansion column. |
