Antibacterial Surface Modification for Medical Devices

The invention relates to a medical device comprising a biocompatible material having an exposed surface prone to biofilm growth. The biocompatible material comprises a doping of an antibacterial metal compound. A concentration of the doping compound ranges from 1% to 30% (w/w) within an outer layer adjacent to the exposed surface, and is essentially zero within a bulk layer of the biocompatible material.
