  • Publication number: 20140166493
    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.

  • Patent number: 7959349
    Abstract: A device for mixing and applying mixed material, in particular medical cement, comprising a cartridge cylinder, a mixer, a plunger for closing the mixed material cavity and for forcing out the mixed material from the cartridge cylinder, and a latching ring having radially outer and inner hook formations. First counter-hooks on the cartridge cylinder interact with the radially outer hook formations on the latching ring. The plunger has second counter-hooks which interact with the inner hook formation on the latching ring in order to hold the plunger during the mixing, and release the plunger for being displaced at the beginning of the application procedure.
