ABSTRACT:
The invention is directed to an expandable stent which is longitudinally flexible in both the unexpanded and expanded conditions. The stent includes spiral structures which at least partially unwind upon expansion of the stent to limit stent recoil. Regions of low strain in the stent during expansion are provided by the spiral structures.
