Patent

CA 2557029

A metal implant for use in a surgical procedure is provided with a surface layer that is integral with the metal substrate, and which incorporates a biocidal material. The surface layer is grown by anodising at a voltage between 50 and 150 V, and the biocidal material incorporated in it by ion exchange. This produces a significantly harder surface than anodising at low voltage, and generates pits containing ion-absorbing material.

Implant métallique conçu pour être utilisé dans une intervention chirurgicale et comportant une couche superficielle solidaire du substrat métallique, tout en incorporant un matériau biocide. La couche superficielle est créée par anodisation à une tension entre 50 et 150 V et le matériau biocide est incorporé dans ladite couche par échange d'ions. Ceci permet d'obtenir une surface considérablement plus dure que par anodisation à basse tension et de générer des puits contenant un matériau absorbeur d'ions.
