APPARATUS AND METHODS FOR ACOUSTICALLY OR MECHANICALLY STIMULATING A COCHLEA AND INTRACOCHLEAR RECORDING OF MECHANICALLY OR ACOUSTICALLYEVOKED AUDITORY POTENTIALS IN THE COCHLEA

摘要

An apparatus for acoustic or mechanical stimulation of a cochlea and meas urement of acoustically or mechanically evoked electrophysiologic responses from the cochlea is provided. In one example, the apparatus includes an acou stic stimulator for generating an acoustic signal and an electrophysiologic response measuring device positioned proximal the cochlea or within the coch lea for measuring an acoustically evoked electrophysiologic response to the acoustic signal. Methods of utilizing the apparatus for diagnostic and thera peutic procedures related to hearing impairment are also provided.
