Electrophysiological measurement method and system for positioning an implantable, hearing instrument transducer
First Claim
1. A system for positioning an implantable hearing instrument transducer relative to a patient'"'"'s middle ear component or inner ear, comprising:
- a signal source for supplying test signals to an implantable hearing instrument transducer as positioned at each of a plurality of different positions within a patient'"'"'s middle ear or inner ear;
an electrocochleography measurement device, interconnectable with said signal source, for measuring an electrical potential, associated with at least one of a cochlea and an auditory nerve of the patient, in timed relation to each of said test signals and for providing measurement signals in corresponding relation thereto; and
,a processor for processing said measurement signals to provide an output relating to the desirability of at least one of said plurality of positions of said implantable hearing aid transducer.

Abstract
An electrophysiological measurement method and system is provided for positioning an implantable transducer of a hearing instrument relative to a middle ear component or inner ear of a patient. The method and system employ electrophysiological measurement signals obtained in response to test signals applied to an implanted transducer. In one embodiment, the electrophysiological measurements are obtained by an electrocochleography measurement device that measures the cochlear summating potential and/or action potential responsive to test signals applied to an implanted transducer. In another embodiment, an auditory brainstem response measurement device is utilized to obtain electrical potential measurement signals responsive to test signals applied to an implanted transducer.
