A radially expandable stent (

10

) made from a cannula or sheet of biocompatible material that includes at least one longitudinal segment (

14

) comprised of a series of laterally interconnected closed cells (

13

). Each closed cell of a longitudinal segment is defined laterally by a pair of longitudinal struts (

15, 16

) that are interconnected at each end by a circumferentially adjustable member (

19, 20

). When the stent is expanded using a balloon (

47

), the opposing circumferentially adjustable members deform to allow circumferential expansion of the longitudinal segment, while the length of the segment, as defined by the longitudinal struts, is maintained. Self-expanding versions of the stent utilize a nickel-titanium alloy. Adjacent longitudinal segments are joined by flexible interconnection segments (

21

) that permit the stent to bend laterally. The flexible interconnection segment is comprised of curvilinear struts (

22, 23

) that form a series of serpentine bends (

81

) that distribute lateral bending forces. In a preferred embodiment, a short strut interconnects longitudinal segments and an adjacent interconnection segment. Each interconnection strut attaches to the longitudinal segment within a region (

27

) at the end (

17

) of a longitudinal strut (

15

) dividing two adjacent closed cells.
