  • Patent number: 10010652
    Abstract: The present invention relates generally to a bio-degradable implant based on magnesium having a reduced corrosion rate and to a method for the production of such an implant. It is a method for treating a surface of a bio-degradable metallic implant comprising the following steps: providing a dispersed system comprising a colloid-dispersed apatite and adding an apatite powder to the dispersed system, subjecting an implant to the dispersed system such that a surface of the implant which is to be treated is immersed in the dispersed system wherein the implant comprises a magnesium based alloy, applying an AC voltage difference between the implant as a first electrode and a second electrode positioned in the dispersed system for generating a plasma electrolytic oxidation on the immersed surface of the implant so that the immersed surface is converted to an oxide film which is at least partially covered by apatites formed by the colloid-dispersed apatite and the apatite powder.

  • Publication number: 20150114840
    Abstract: An antibacterial coating that is composed of silver is disclosed, as well as medical tools and implants comprising such a coating, and a method and an apparatus for the production of such a coating. The medical tools or the dental or orthopaedic implant comprises a metal or metal alloy having a treated surface wherein the treated surface is at least partially converted to an oxide film by plasma electrolytic oxidation using a colloid-dispersed system and wherein the converted surface is partially covered by islands formed by colloid-dispersed silver-particles of the colloid-dispersed system. An Ag—TiO2 coating shows excellent properties in terms of antibacterial efficacy (even against multi-resistant strains), adhesion and biocompatibility. The life-time of an implant in a human body is increased. The antibacterial coating can be used in the field of traumatology, orthopaedic, osteosynthesis and/or endoprothesis, especially where high infection risk exists.

  • Patent number: 8003121
    Abstract: System of implant components containing active agents, wherein each component is intended to function as an additive for an implant material produced with a powdery or finely granulated starting material and/or active agents and additives. Each component is powdery or finely granulated and includes at least one powdery or finely granulated active agent or additive having a higher dosage than the desired concentration for the application. The components themselves are made of a powdery or finely granulated starting material for the implant material, as well as of the active agent or additive. The active agents can be chemotherapeutical agents, such as antibiotics, whereas the additives can be x-ray contrast materials and/or or additives that alter the physical properties of the starting material, such as its elasticity or viscosity.
