1. A method of forming a patterned conductive element for an implantable medical device, the method comprising the steps of:
- depositing a supplementary material on a sheet of conductive, parent material to form a sheet of composite material;
applying a carrier material over the supplementary material of the composite sheet to form a sheet of semi-finished material;
removing portions from at least the conductive parent material of the sheet of semi-finished material in accordance with a desired pattern corresponding to a patterned conductive element to be formed; and
releasing at least the carrier material from the sheet of semi-finished material.
