摘要: This invention provides biodegradable, biocompatible polymeric films having uniform selected thicknesses between about 60 micrometers and about 5 mm useful in the manufacture of therapeutic implants for insertion into a patient's body. The films may be shaped to cover implants made of other materials to improve their biocompatibility. The films may be coated with or incorporate bioactive agents. They may have differing properties, e.g., porosity, thickness, and degradation rate, in different areas.
