Abstract
A method, including the action of executing a first evaluation including evaluating first interactions of respective current spreads with one another for a plurality of first electrodes implanted in a recipient resulting from energizement thereof with at least one second implanted electrode disabled, wherein the second electrode, if enabled and energized at about the same level as at least one of the first electrodes, would result in current spread to at least one of the plurality of first electrodes, and one of disabling at least one third electrode of the plurality of first electrodes based on the evaluation or maintaining an enablement of the nondisabled electrodes based on the evaluation.
Claims29
A method, comprising:
- evaluating at least one of interactions of respective current spreads with one another or interactions of respective neural spreads with one another for a plurality of electrodes implanted in a recipient;
- disabling or disadvantaging at least one electrode based on the evaluation;
- applying electrical current to the electrodes of the plurality of electrodes to generate the respective current spreads and/or to evoke the neural spreads;
- using in-vivo electrode voltage telemetry (EVT) to obtain data to enable the evaluation of the at least one of interactions of respective current spreads with one another or interactions of respective neural spreads with one another for the plurality of electrodes implanted in a recipient, wherein
- the action of evaluating the at least one of interactions of respective current spreads with one another or interactions of respective neural spreads with one another for the plurality of electrodes implanted in a recipient includes comparing voltage based data of the obtained data.
A method, comprising:
- evaluating at least one of interactions of respective current spreads with one another or interactions of respective neural spreads with one another for a plurality of electrodes implanted in a recipient;
- disabling or disadvantaging at least one electrode based on the evaluation;
- applying electrical current to the electrodes of the plurality of electrodes to generate the respective current spreads and/or to evoke the neural spreads;
- obtaining data indicative of respective current spreads for the electrodes by:
- applying respective stimulation currents to respective first electrodes in temporally non-overlapping manner;
- and
- obtaining data indicative of transimpedance at respective first electrodes while the respective stimulation currents are applied, wherein
- the action of evaluating the at least one of interactions of respective current spreads with one another or interactions of respective neural spreads with one another for the plurality of electrodes implanted in a recipient includes comparing data indicative of the transimpedance for the respective electrodes for the respective currents applied to the electrodes of the plurality of electrodes, developing weighting factors for the respective electrodes based on the comparison of the data indicative of transimpedance for the respective electrodes.
