1. A stent comprising:
- a plurality of strut bands, each strut band forming a closed path of alternating peaks and troughs, wherein strut bands adjacent one another are connected by a plurality of connectors,each strut band comprising a plurality of long struts, a plurality of short struts, and a plurality of junctions, each junction being positioned between and connecting a first short strut and a second short strut, each long strut being connected to a first short strut at a peak and each long strut being connected to a second short strut at a trough,each junction defining only a single junction reservoir, all of the junction reservoirs of a strut band being circumferentially aligned,each connector comprising a first arm which extends from a junction on one strut band, and a second arm which extends from a junction on an adjacent strut band, at least a portion of the first arm comprising a first U-shaped link and at least a portion of the second arm comprising a second U-shaped link, each first U-shaped link opening in a first direction and each second U-shaped link opening in a second direction substantially opposite the first direction, at least a portion of the first U-shaped link and at least a portion of the second U-shaped link having a shared portion, the shared portion disposed between one of the peaks on one strut band and a longitudinally adjacent trough of an adjacent strut band.

Abstract
A stent with strut bands and connectors, wherein the strut bands have long and short struts with a junction positioned between the short struts. Each junction defines a reservoir, wherein the reservoirs of a strut band are substantially circumferentially aligned. The connectors each have arms, wherein each arm includes an opposing U-shaped link. The opposing links have a shared portion disposed between a peak on one strut band and a longitudinally adjacent trough of an adjacent strut band.
