ABSTRACT:
A method of forming a device, such as an electrode array for a cochlear implant. The method comprises a step of forming a predetermined pattern of relatively electrically conductive regions and relatively electrically resistive regions in a sheet of biocompatible electrically conductive material, such as platinum foil. The method can comprise a step of working on the sheet to remove predetermined portions therefrom to form the one or more discrete relatively conducting regions. The step of working on the sheet can comprise embossing the sheet, cutting or slicing the sheet, or using electrical discharge machining (EDM) to remove unwanted portions of the sheet, the EDM equipment having a cutting tool comprising an electrode.
