US 2026/0158283 A1 · IMPLANTABLE ELECTRODE ARRAY POSITION MONITORING

Abstract

Presented herein are techniques to determine the placement/position of one or more parts of an electrode array during or after surgery. The techniques presented herein use a “positioning model” (positioning algorithm) to estimate (predict) the positioning/placement of an electrode array and/or estimate positioning/placement features (e.g., depth of basal electrode, modiolar proximity, polar or Cartesian coordinates of electrodes, etc.) of the electrode array inside of a recipient's body chamber (e.g., cochlea) during and after insertion. More specifically, the techniques presented herein use measurements (e.g., voltage measurements) obtained from the body chamber of the recipient as an input to a trained model/algorithm to estimate/predict the position of an electrode array within the body chamber of the recipient.

Dependent claims

A method, comprising:

determining an insertion depth of a basal part of an elongate electrode array within a body chamber of a recipient, wherein the electrode array comprises a plurality of longitudinally spaced electrodes;
obtaining one or more electrical measurements from the body chamber of the recipient;
and
determining a value for a key position of the elongate electrode array using a relationship between at least the determined insertion depth of the basal part of the elongate electrode array and the one or more electrical measurements.
