Abstract
Provided are oriented biodegradable thermoplastic polyurethane films. The films may be prepared by extruding and drawing biodegradable polyurethane films. The polyurethanes may be prepared from biodegradable polyols and/or biodegradable chain extenders. The films possess high tensile strength yet are degradable under biological conditions. The films may be utilized in the fabrication of devices, particularly implantable medical devices.
