    摘要: Preferred embodiments of the present invention relate to polymeric medical devices, such as stents. More particularly, the polymeric compositions disclosed herein comprise halogen-containing, tyrosine-derived diphenols, optionally in conjunction with other groups, such as dicarboxylic acids and/or poly(alkylene oxide), 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.
