摘要:
Implantable or insertable medical devices are described, which include one or more polymeric regions and one or more therapeutic agents. The polymeric regions, which regulate the release of one or more therapeutic agent from the medical device, contain copolymer molecules, each of which includes one or more soft segments and one or more uniform hard segments (e.g., polyamide segments that do not vary in length from molecule to molecule, among others).
