  • AUDITORY PROSTHETIC DEVICES USING EARLY AUDITORY POTENTIALS AS A MICROPHONE AND RELATED METHODS
    Publication number: 20220313998
    Abstract: Described herein are devices and methods that use the electrical potentials that arise naturally in the cochlea through the activity of sensory cells and auditory neurons and resemble the output from a microphone. An example auditory prosthetic device includes an electrode array that is configured for insertion into at least a portion of a subject's cochlea and a receiver-stimulator operably coupled to the electrode array. The electrode array is configured for electrical recording and stimulation.

  • Apparatus and methods for acoustically or mechanically stimulating a cochlea and intracochlear recording of mechanically or acoustically evoked auditory potentials in the cochlea
    Patent number: 9380962
    Abstract: An apparatus for acoustic or mechanical stimulation of a cochlea and measurement of acoustically or mechanically evoked electrophysiologic responses from the cochlea is provided. In one example, the apparatus includes an acoustic stimulator for generating an acoustic signal and an electrophysiologic response measuring device positioned proximal the cochlea or within the cochlea for measuring an acoustically evoked electrophysiologic response to the acoustic signal. Methods of utilizing the apparatus for diagnostic and therapeutic procedures related to hearing impairment are also provided.
