Abstract:
1. A method of forming a biocompatible medical device comprising selecting a polyhydroxyalkanoate, which is prepared using a process which introduces a pyrogen into the polyhydroxyalkanoate, removing the pyrogen from the polyhydroxyalkanoate from the polyhydroxyalkanoate to produce a pyrogen level of less than 20 endotoxin units (EU) per device by exposing the polyhydroxyalkanoate to an oxidizing agent and/or hydrolysis, so that the polyhydroxyalkanoate does not elicit a pyrogenic response when implanted into an animal, and forming the device.
