摘要: The invention relates to an implant with a coating (23) which releases silver ions in the human body and as a result has antimicrobial action. According to the invention, a first surface component of the coating (23) is formed by an anode material (25). A second surface component of the coating (23) is formed by a cathode material (26). The cathode material is higher in the electrochemical voltage series than the anode material (25). The cathode material (26) and the anode material (25) are connected to one another in an electrically conductive manner. Together with the body electrolyte in the environment of the implant, the anode material (25) and the cathode material (26) form a multitude of local galvanic elements. The antimicrobial action of the coating (23) is improved as a result.

摘要: In a prosthesis component of a joint endoprosthesis, the prosthesis component comprises a sliding surface that is designed to form a sliding joint with a counter sliding surface of another prosthesis component. The sliding surface may be formed by a sliding surface coating deposited on the body of the prosthesis component, wherein the sliding surface coating has an antimicrobial effect. The sliding surface coating is active against microorganisms in the area of the sliding joint.

摘要: In a coated implant that releases silver ions in the human body and thereby has an antimicrobial effect, a first surface component of the coating is formed by an anode material. A second surface component of the coating is formed by a cathode material. The cathode material is higher in the electrochemical voltage sequence than the anode material. The cathode and the anode are connected with one another in an electrically conducting manner. Together with the body electrolyte in the vicinity of the implant the anode and the cathode material form a plurality of local galvanic elements.

摘要: In a first aspect, the present invention discloses a self setting calcium phosphate cement comprising:—(i) a powdered component, said powdered component having an average particle size d50 of less than 15 μm, and (ii) a calcium phosphate based powder, said powder having an average particle size d50 greater than that of the powdered component, said powdered component and said calcium phosphate based powder being suspended in water containing a dissolved zeta potential increasing additive in sufficient quantity to increase the zeta potential of the suspended particles to at least 30 mV, and wherein the zeta potential increasing additive is chosen to be compatible with the setting pH of the same calcium phosphate cement without the zeta potential increasing additive. In a second aspect, the invention discloses a shelf-stable acidic setting cement powder comprising:—(i) a calcium phosphate based powder, and (ii) a powdered compound which, upon addition of water to form a cement paste, retards the cement setting reaction or increases the zeta potential of the resultant suspended particles to at least −30 mV.
