Tubular stent consists of horizontal expansion struts and contralaterally attached diagonal-connectors
First Claim
1. A circumferentially connected stent in a non-expanded state with a longitudinal axis, comprising:
- a plurality of expansion struts forming a first expansion column, the first expansion column including a first expansion strut, a second expansion strut and a first joining strut coupling a distal end of the first expansion strut to a distal end of the second expansion strut, the first expansion strut having a stepped distal portion and the second expansion strut having a stepped proximal portion;
a plurality of expansion struts defining a second expansion column, the second expansion column including a first expansion strut, a second expansion strut and a first joining strut coupling a distal end of the first expansion strut to a distal end of the second expansion strut, the first expansion strut having a stepped proximal portion and the second expansion strut having a stepped distal portion; and
a first serial connecting strut column formed of a plurality of serial connecting struts and including a first serial connecting strut, the first serial connecting strut column coupling the first expansion column to the second expansion column.

Abstract
A circumferentially connected stent in a non-expanded state with a longitudinal axis, including a plurality of expansion struts forming a first expansion column, the first expansion column including a first expansion strut, a second expansion strut and a first joining strut. The first joining strut couples a distal end of the first expansion strut to a distal end of the second expansion strut, and the first expansion strut has a stepped distal portion and the second expansion strut has a stepped proximal portion. A plurality of expansion struts defines a second expansion column, and the second expansion column includes a first expansion strut, a second expansion strut and a first joining strut which couples a distal end of the first expansion strut to a distal end of the second expansion strut, and the first expansion strut has a stepped proximal portion and the second expansion strut haves a stepped distal portion. A first serial connecting strut column is formed of a plurality of serial connecting struts and includes a first serial connecting strut. The first serial connecting strut column couples the first expansion column to the second expansion column.
