Abstract

A lead for use in Deep Brain Stimulation (DBS) and similar applications has a rigid lead tip with multiple electrodes thereon. The electrodes are formed by coating a lead tip core with a conductive material; selectively removing the conductive material to define the electrodes and conductive tracks leading therefrom; and then applying a layer of insulating material over the tracks to leave the electrodes exposed. Terminals are also left exposed on the tracks for connection to energy supply and/or data transmission lines. Such lines are preferably provided on or within a flexible lead body connected to the lead tip.
