  • placing a medical device in a plasma chamber;

    reducing the atmospheric pressure within said plasma chamber to provide a process pressure of less than approximately 760 Torr;

    providing a non-reactive gas to said plasma chamber while maintaining said process pressure of less than approximately 760 Torr; and

    exposing said medical device to said gas phase plasma to achieve surface heating of said device to the point where the surface glows, thereby producing a non-random textured surface on said medical device.
