Open the CIPO recordAbstract From the Canadian patent
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.
