In at least one embodiment, a stent includes an unexpanded configuration, a nominally expanded configuration, and a fully expanded configuration. The stent further includes a plurality of circumferential bands and a plurality of connectors connecting adjacent circumferential bands to one another. Each circumferential band has a plurality of struts interconnected by bridges. Adjacent struts form strut pairs and are connected to one another at a first end or a second end but not both. Each strut pair defines an opening between the struts of the strut pair; the bridges extend into the openings. In the unexpanded configuration, the struts are straight along their length. Also in the unexpanded configuration, the bridges include two adjacent straight segments that are connected by a u-shaped segment, and the straight segments are parallel to one another and to the longitudinal axis of the stent. |
