  • Publication number: 20200017966
    Abstract: A medical device intended for contact with living tissue comprises a substrate having a surface, which surface comprises a layer comprising gallium oxide. A layer comprising a gallium oxide 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 gallium compound onto said surface to form a layer, preferably using a thin film deposition technique.
    Type: Application

  • Patent number: 9889237
    Abstract: A medical device has a surface intended for contact with living tissue, wherein the surface comprises nanoparticles comprising a non-toxic post-transition metal such as gallium and/or bismuth, said nanoparticles having an average particle size of 500 nm or less. The nanoparticles may provide an antimicrobial effect, and thus the risk for infection may be reduced.

  • 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.
