Intravascular stent
First Claim
1. A stent comprising a plurality of longitudinally adjacent columns, each column formed of a plurality of struts, the plurality of columns including first columns and second columns, each of the struts of at least one of the first columns having a first width, each of the struts of at least one of the second columns having a second width less than the first width, the struts of at least one of the first columns interconnected by turns, one second column engaging two adjacent first columns, the struts of the second column extending between a turn of one of the adjacent first columns and a turn of the other of the adjacent first columns, each strut of the second column having at least two bends, a first end, and a second end, the first end longitudinally and circumferentially displaced from the second end.

Abstract
A stent in a non-expanded state has a first and second expansion column, each consisting of a plurality of expansion strut pairs. An expansion strut pair includes a first expansion strut, a second expansion strut and a joining strut that couples the first and second expansion struts at one end. A connecting strut column, formed of a plurality of connecting struts couples the first and second expansion columns. Connecting struts include a proximal section, a distal section and an intermediate section. The proximal section is coupled to the corner of an expansion strut pair of the first expansion column, and the distal section is coupled to the joining strut of an expansion strut pair of the second expansion column intermediate the expansion strut pair first corner and the expansion strut pair second corner.
