Abstract
Methods of making a biodegradable polymeric stent made from poly(L-lactide) and a low concentration of L-lactide monomer is disclosed. The concentration of L-lactide is adjusted to provide a degradation behavior that is suitable for different treatment applications including coronary, peripheral, and nasal. Methods include making a poly(L-lactide) material for a stent with uniformly distributed L-lactide monomer through control of polymerization conditions during PLLA synthesis, control of post-processing conditions, or both.
