  • Measurement of evoked neural response
    Patent number: 7809445
    Abstract: A method and device for measuring an evoked neural response comprising a sensor (25) for obtaining a sensed signal representing the evoked neural response, a high gain amplifier (30) having a signal input (31) for receiving the sensed signal and having a reference input (32), and means for altering or setting a reference voltage at the reference input (32) to prevent the amplifier (30) saturating with variations of the sensed signal.
    Type: Grant
    Filed: September 4, 2003
    Date of Patent: October 5, 2010
    Assignee: Cochlear Limited
    Inventors: Helmut Christian Eder, Padraig Joseph Hurley, David Kerry Money, Tony Mikeal Nygard
  • Telemetry system and apparatus
    Patent number: 5758651
    Abstract: A system is disclosed for enabling telemetry from an auditory prosthesis, illustratively a cochlear prosthesis. An electrode array 10 is used both for delivering electrical stimuli, and for sensing evoked potentials. Preferably a delay is provided between stimulus and measurement, and the sensing electrodes are distinct from the stimulus electrodes.

  • Cochlear implant system with soft turn on electrodes
    Patent number: 5755747
    Abstract: An implanted device such as a cochlear implant system includes a housing containing stimulating pulse generating circuitry, and a plurality of electrodes external of the housing and receiving the pulses. Between the pulses, parasitic voltages may build up between the electrodes. In order to control the inrush current due to these parasitic voltages, multi-position switches are provided which selectively couple the electrodes to resistors selected to dissipate the voltages at a preselected maximum current to protect the body organs.
