Abstract
A radially expandable stent ( ) made from a cannula or sheet of biocompatible material that includes at least one longitudinal segment ( ) comprised of a series of laterally interconnected closed cells ( ). Each closed cell of a longitudinal segment is defined laterally by a pair of longitudinal struts ( ) that are interconnected at each end by a circumferentially adjustable member ( ). When the stent is expanded using a balloon ( ), 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 ( ) that permit the stent to bend laterally. The flexible interconnection segment is comprised of curvilinear struts ( ) that form a series of serpentine bends ( ) 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 ( ) at the end ( ) of a longitudinal strut ( ) dividing two adjacent closed cells.
