<p>The stent has a plurality of bridge elements (8) having a U-shaped portion between first and second connector arms, the first connector arm of one bridge element being connected between a first peak and a first valley of the first segment (2) and the second connector arm being connected between a first peak and a first valley of the second segment (2) in a manner such that the U-shaped portion extends in the direction of the first peak of the first segment and the first valley of the second segment. The segments (2) and bridge elements (8) are configured such that when compression, flexure, and torsion forces are applied to the stent they generate first maximum stress regions, second maximum stress regions and third maximum stress regions which do not overlap. This is achieved by manufacturing the stent for starting from a tubular blank including opposed surfaces (51, 53) separated by a non-uniform wall thickness (55) providing different thicknesses at different parting of the stent. <IMAGE></p> |
