1. A stent, comprising: a tubular member having a plurality of rings spaced apart along a longitudinal axis, each ring having a distal end and a proximal end, each ring having a first delivery position and a second expanded position; the rings having curved portions forming a plurality of distally-extending peaks and a plurality of proximally-extending peaks, the distally-extending peaks and the proximally-extending peaks being connected by first struts and second struts, the second strut having a width which tapers from a first width to a second, larger width, wherein adjacent distally-extending peaks are spaced apart to define a space therebetween when the rings are in the first delivery position, the space extending from a first strut and second strut on each ring to the ends of the adjacent distally-extending peaks; and a plurality of S-shaped links for connecting adjacent cylindrical rings, a portion of the S-shaped links being integrally formed from a portion of the second struts, each of the S-shaped links extending from the larger width of the second strut, wherein a portion of the second struts splits into a first link arm and a bar arm, the first link arm being separated from the bar arm by a gap, each S-shaped link including a second link arm and a third link arm, the first, second and third link arms being connected together and placed in a side-by-side relationship and at least a portion of each of the first, second and third link arms is located within the above-defined space when the rings are placed in the first delivery position.
