Abstract:
A stent and method for manufacturing a stent that achieves both strength as well as ductility. In the manufacturing process, the material used to form the stent is only partially annealed to lower the grain size across the thickness of the stent. The material is partially annealed either prior to or after the cutting a stent pattern into a tube.
