  • Materials and technologies used in crafting of multi-electrode spiral cuffs for VNS [Elektronski vir]
    Godec, Matjaž, 1961-
    We review the methodology and technology of crafting a multi-electrode spiral cuff for fibre-type selective activation of fibers in particular superficial regions of a vagus nerve. In this relation, ... the design criteria and structural properties of the spot welds interconnecting platinum stimulating electrodes and stranded stainless steel lead wires, are presented. To reveal the microstructure of the weld obtained under specific welding conditions, the most advanced metallographic method of scanning electron microscopy, was used. Obtained results provide evidence that a portion of material within the spot melts without having the entire spot melt and that the chemical properties such metal%s internal resistance and its corrosive properties were not greatly affected. The resulting cuff consisted of 33 platinum electrodes embedded within a self-curling silicone spiral sheet with a nominal internal diameter of 2.5 mm to fit the size of the human cervical vagus nerve.
