  • Publication number: 20140017628
    Abstract: A wireless, remote foot controller and a wireless instrument in direct communication with one another and method of operation. The remote foot controller can determine the wireless instrument in the hand of the dental professional and can determine whether the instrument is operational in an continuously variable mode or whether the instrument is operational at discrete speeds. The remote foot controller can then respond to activation by a user to provide a predetermined signal that drives the handheld unit with the appropriate signal. The remote foot controller is activated by application of pressure to the foot controller that provides tactile, sensory feedback to the user. The foot controller includes a circuit board, antenna and battery so that it is wireless. The circuit board includes communications protocol to permit the foot controller to communicate with several dental instruments.

  • Publication number: 20130266629
    Abstract: A medical device intended for contact with living tissue comprises a substrate having a surface, which surface comprises a layer comprising one or more compound(s)) of at least one non-toxic post-transition metal, such as a gallium or bismuth compound. A layer comprising a compound of a non-toxic post-transition metal has been shown to inhibit biofilm formation on the surface of the medical device, which may reduce the risk for infection e.g. around a dental implant. A method of producing the medical device comprises: a) providing a substrate having a surface; and applying a compound of a non-toxic post-transition metal onto said surface to form a layer, e.g. using a thin film deposition technique.
