  • System and method for electrically shielding a microelectrode array in a physiological pathway from electrical noise
    Patent number: 8855737
    Abstract: A system and method for electrically shielding a physiological pathway from electrical noise is disclosed. The method includes the operation of implanting at least one signal microelectrode into a patient such that the signal microelectrode is proximate to the physiological pathway. An additional operation includes substantially enclosing the microelectrode and a section of the physiological pathway with an electrical shielding wrap. The electrical shielding wrap includes a plurality of holes that enable fluid communication of physiological fluids between an inside and outside of the wrap.
    Type: Grant
    Filed: December 30, 2013
    Date of Patent: October 7, 2014
    Assignee: University of Utah Research Foundation
    Inventors: Gregory Arthur Clark, David James Warren, Noah M. Ledbetter

  • Microelectrode array system with integrated reference microelectrodes to reduce detected electrical noise and improve selectivity of activation
    Patent number: 8359083
    Abstract: A microelectrode array system used to sense physiological signals and stimulate physiological tissue to form signals is disclosed. The array includes a dielectric substrate and a two dimensional array of signal microelectrodes substantially perpendicular to and integrated on the dielectric substrate. At least one reference microelectrode is located adjacent to and integrated with the signal microelectrodes on the dielectric substrate. The reference microelectrodes are positioned on the dielectric substrate relative to the signal microelectrodes to enable a reduced level of electrical noise to be detected between the reference microelectrodes and the recording microelectrodes.
