Abstract
Presented herein are techniques for monitoring the insertion of an intra-cochlear stimulating assembly for the occurrence of one or more insertion stop conditions. The insertion stop conditions are detectable events indicating that movement of the stimulating assembly into a recipient's cochlea should be at least temporarily stopped. The insertion monitoring is based on objectively measured inner ear potentials, such as acoustically-evoked potentials.
Claims14
A method, comprising:
- pre-operatively determining an initial insertion stop frequency of a cochlea of a recipient;
- inserting a stimulating assembly into the cochlea of the recipient towards the pre-operatively determined initial insertion stop frequency;
- during insertion of the stimulating assembly into the cochlea of the recipient, obtaining intra-operative acoustically-evoked inner ear potentials from the cochlea;
- analyzing the intra-operative acoustically-evoked inner ear potentials obtained from the cochlea in view of normative data to determine a revised insertion stop frequency;
- detecting, based on continued monitoring of the intra-operative acoustically-evoked inner ear potentials, occurrence of an insertion stop condition associated with the revised insertion stop frequency;
- and
- responsive to detection of the occurrence of the insertion stop condition, initiating, at an intra-operative system, a feedback mechanism.
