Abstract:
1. A sensor for sensing the electrical activity within a nerve, the sensor comprising: a sensor body having a first and second surface adapted to be positioned proximate to the nerve so as to be able to sense electrical activity within the nerve; at least one electrode formed adjacent the first surface of the sensor body so as to be able to either sense electrical activity within the nerve or deliver electrical stimulation to the nerve when the sensor body is positioned proximate to the nerve; a shielding element coupled to the sensor body wherein the shielding element is insulated from the at least one electrode and wherein the shielding element comprises a plurality of openings and wherein the shielding element is adapted to shield the at least one electrode from electromagnetic radiation to improve the ability of the at least one electrode to sense electrical activity within the nerve; wherein the shielding element comprises a mesh of conducting material formed on the second surface; wherein the mesh is sized so as to inhibit electromagnetic radiation of a frequency of greater than about 10 kHz from traveling inward towards the at least one electrode; and wherein the mesh is formed by photolithographic deposition.
