  • Methods for neurostimulator pulse overlap control
    Patent number: 11691016
    Abstract: Patients with spinal cord injuries have benefited from neurostimulation therapy comprising delivery of electrical stimulation to enable or excite neurological responses using an implantable neurostimulator having an electrode array. Dangerous levels of charge are avoided while providing multiple, simultaneous stimulation waveforms by inducing a short in an electrode when a monitored value reaches or exceeds a predetermined threshold.
    Type: Grant
    Filed: April 19, 2019
    Date of Patent: July 4, 2023
    Assignee: University of Louisville Research Foundation, Inc.
    Inventors: Susan J. Harkema, Yangsheng Chen, Claudia Angeli, Douglas J. Jackson, Manikandan Ravi, John Naber, Robert S. Keynton, Thomas Roussel, Saliya Kirigeeganage
