    摘要： A stent incorporating flexible, preferably polymeric, connecting elements into the stent wherein these elements connect adjacent metallic stent element(s) across an intervening space and have optimized geometries. In one configuration the metallic elements are the result of forming the stent from a helically wound serpentine wire having intervening spaces between adjacent helical windings of the wire. The polymeric connecting elements are designed to fold within the space between the outer diameter of the stent and the inner diameter of the stent when the stent is subjected to compaction or bending. Other stent forms such as multiple, individual spaced-apart ring-shaped or interconnected stent elements may also be used.
