ABSTRACT:
An improved process for manufacturing a molded prosthetic device from a synthetic bioabsorbable polymer is disclosed. The process includes placing a solid amount of the polymer in a molding machine; melting the polymer by subjecting it to a temperature of from about 240.degree. to 255.degree. C. for about 2 to 5 minutes; transporting the polymer melt to an orifice; injecting the polymer melt from the orifice into a closed mold cavity at a pressure of from about 8000 to 9000 lbs per square inch (562 to 633 kg per sq. cm.); holding the polymer in the mold cavity for less than about one minute at a temperature of about 70.degree. to 90.degree. C.; removing a molded prosthetic device from the mold cavity; and posttreating the molded prosthetic device. The posttreating can be, e.g., annealing and then/or sterilizing.
