PROBLEM TO BE SOLVED: To provide bioresorbable and radiopaque polymeric medical devices, such as stents.SOLUTION: Polymeric compositions comprise halogen-containing, tyrosine-derived diphenols, optionally in conjunction with other groups, such as dicarboxylic acids and/or poly(alkylene oxides), such that the medical devices made from these polymeric compositions are bioresorbable and inherently radiopaque, and exhibit physicomechanical properties consistent with the intended uses of such devices. |
