    摘要: An implantable medical device is disclosed. The device is fabricated at least in part from a biocompatible, biodegradable composition. The composition is composed of a biocompatible, biodegradable polymer and a biocompatible, biodegradable wax. The concentration of the wax at the surface of the device is greater than the concentration of the wax in the body of the implantable device. The increased concentration of wax at the device surface may be attained when the device is heated to a temperature greater than the melting point of the wax and the glass transition temperature of the polymer, but lower than melting point of the polymer.
