Flexible stent with improved axial strength
First Claim
1. A stent comprising a plurality of serpentine generally cylindrical bands, bands which are adjacent one another connected one to the other, at least one of the bands formed in a pattern of alternating first and second struts extending between turns, wherein each first strut is located adjacent to and between two second struts and each second strut is located adjacent to and between two first struts, the first struts being stronger than the second struts, the first and second struts being of substantially the same length;
- wherein the first struts are formed of a different material than the second struts.

9. A stent comprising a plurality of serpentine generally cylindrical bands, bands which are adjacent one another connected one to the other, at least one of the bands formed in a pattern of alternating first and second struts extending between turns, each of the first and second struts extending between one turn at a proximal end of the band and another turn at the distal end of the band, wherein each first strut is located adjacent to and between two second struts and each second strut is located adjacent to and between two first struts, the first and second struts extending in a substantially longitudinal direction, the first struts being stronger than the second struts;
wherein the first struts are formed of a different material than the second struts. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
- 25. A stent comprising a first, second and third serpentine substantially circumferential band, each serpentine band having a plurality of turns with struts extending therebetween, the second band disposed between the first and third bands, and connected to the first band via a plurality of first connections and the second band connected to the third band via a plurality of second connections, the second band being arranged in an alternating pattern of wide and narrow struts, each wide strut disposed between two narrow struts and each narrow strut disposed between two wide struts, the wide struts and the narrow struts having the same length, there being at least three struts of the second band extending between first and second connections which are nearest one another.
