  • Overvoltage protection circuitry
    Patent number: 10279173
    Abstract: Overvoltage protection circuitry configured to protect internal integrated circuits within an implantable device in the presence of a high voltage event such as defibrillation or electrocautery. The circuitry allows for an internal node to rise above the voltage level of the high voltage event to insure that an overvoltage protection element is triggered, even if the voltage level of the high voltage event is below the voltage trigger level of the overvoltage protection element.
    Type: Grant
    Filed: December 27, 2016
    Date of Patent: May 7, 2019
    Assignee: Medtronic, Inc.

  • Adaptable current regulator for delivery of current-based electrical stimulation therapy
    Patent number: 9056206
    Abstract: A medical electrical stimulator provides selective control of stimulation via a combination of two or more electrodes coupled to respective regulated current paths and one or more electrodes coupled to unregulated current paths. Constant current sources may control the current that is sourced or sunk via respective regulated current paths. An unregulated current path may sink or source current to and from an unregulated voltage source that serves as a reference voltage. Unregulated electrodes may function as unregulated anodes to source current from a reference voltage or unregulated cathodes to sink current to a reference voltage.
