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.
本发明的首选实施例涉及聚合物医疗器械,如支架。更具体地说,本文所披露的聚合物组合物包括含卤素的
酪氨酸衍生二
酚,可选地与其他基团结合,例如二
羧酸和/或聚(烷基氧化物),使得由这些聚合物组合物制成的医疗器械具有
生物可吸收性和固有的放射性不透明性,并展现出与此类器械预期用途一致的物理力学性能。
