  • Implanted electrode configuration for physiological sensing and tissue conductance communication
    Patent number: 10610694
    Abstract: In some examples, the disclosure describes an implantable medical device comprising a plurality of electrodes, sensing circuitry configured to sense a physiological electrical signal via the plurality of electrodes, and communication circuitry configured to transmit and/or receive a transconductance communication signal via the plurality of electrodes, wherein at least one electrode of the plurality of electrodes comprises a lower-capacitance portion and a higher-capacitance portion.
    Type: Grant
    Filed: January 20, 2017
    Date of Patent: April 7, 2020
    Assignee: Medtronic, Inc.
    Inventors: James D. Reinke, James K. Carney, Can Cinbis, Richard J. O'Brien, Bushan Purushothaman
  • Lead navigation guidance
    Patent number: 10143839
    Abstract: In some examples, a medical device system includes an electrode. The medical device system may include impedance measurement circuitry coupled to the electrode, the impedance measurement circuitry may be configured to generate an impedance signal indicating impedance proximate to the electrode. The medical device system may include processing circuitry that may be configured to identify a first frequency component and a second frequency component of the impedance signal, and provide an indication of a location of the electrode in a patient based on the first frequency component and the second frequency component.
