Abstract:
1. A method of fabrication of a stimulation lead for electrical stimulation of tissue of a patient, the method comprising: providing a substantially annular substrate of non-conductive material for a stimulation portion of the stimulation lead, wherein the annular substrate is adapted for implantation with a brain of a patient; processing the substrate to create a plurality of recessed features into a surface of the substrate; providing first conductive material over the surface of the substrate to form a first conductive layer for electrical traces and electrodes defined by the plurality of recessed features; subjecting the surface of the substrate to a mechanical grinding process to remove conductive material from portions of the substrate disposed above the plurality of recessed features, wherein each respective connected electrode and electrical trace of conductive material In the plurality of recesses is electrically isolated from the other electrodes and electrical traces after the mechanical processing; electrically plating second conductive material over the first conductive material to provide a second conductive layer for each respective connected electrical trace and electrode; providing insulative material over the plurality of electrical traces; and electrically connecting conductive material of electrical traces with conductor wires of a lead body to connect electrodes of the stimulation portion to wires of the lead body.
