1. A stent having a generally tubular shape and a longitudinal axis and comprising:

  • a plurality of adjacent series of generally radial support struts connected by a plurality of generally flexible connectors, and said radial support struts arranged in a circumferential configuration around the generally tubular shape, said radial support struts comprising alternating long and short struts, a first long strut connected directly to an adjacent second long strut shorter than said first long strut and the same long strut connected directly to an adjacent short strut and said series of generally radial support struts arranged about said strut tubular shape so that adjacent series of struts are spaced apart with no overlap between adjacent series of radial support struts at any radial position when viewing the struts at any longitudinal location about said stent tubular shape to extend longitudinally from a proximal position to a distal position, and wherein there are at least one first series of radial support struts and at least one second series of radial support struts connected by said plurality of generally flexible connectors, the flexible connectors having a pair of ends such that at either end the flexible connectors are connected to a short strut in one of said series of radial support struts, and each series of radial support struts is placed on said stent so that any proximal position of any second series of radial support struts is not placed in a position more proximal than any distal position of said first series of radial support struts.
