Abstract
A method including reducing a stimulation artifact of an implantable stimulator including a plurality of stimulating electrodes by obtaining respective information on respective artifact voltages at a first location resulting from stimulation by one electrode group or respective electrode groups of the implanted stimulator and determining an adjustment regime based on the obtained information that results in a reduction of the stimulation artifact at the first location relative to that which would be the case in the absence of the regime.
Claims25
A method, comprising:
- reducing a stimulation artefact of an implantable stimulator including a plurality of stimulating electrodes by:
- obtaining respective information on respective artefact voltages at a first location resulting from stimulation by one electrode group or respective electrode groups of the implanted stimulator;
- and
- determining an adjustment regime based on the obtained information that results in a reduction of the stimulation artefact at the first location relative to that which would be the case in the absence of the regime,
- wherein the action of obtaining respective information on respective artefact voltages at the first location includes:
- supplying a first electrical current to at least a first electrode implanted in a recipient such that a first stimulating electrical current emanating from the first electrode stimulates tissue of the recipient;
- obtaining a property of an electrical voltage resulting from the first stimulating electrical current at at least one recording electrode that is implanted in the recipient at the first location;
- supplying a second electrical current to at least a second electrode implanted in the recipient such that a second stimulating electrical current emanating from the second electrode stimulates tissue of the recipient;
- and
- obtaining a property of an electrical voltage resulting from the second stimulating electrical current at the at least one recording electrode.

A system comprising:
- a control unit;
- and
- an implantable apparatus including a plurality of electrodes, wherein
- the implantable apparatus is configured to apply, in a controlled manner under the control of the control unit, respective first electrical currents to the respective electrodes of the plurality of electrodes such that respective stimulating electrical currents emanate from the respective electrodes of the plurality of electrodes,
- the system is configured to obtain respective information on respective artifact voltages at a first location resulting from the respective stimulations,
- the application of respective first electrical currents to the respective electrodes corresponds to applying an electrical current to at least a first electrode of the respective electrodes such that a first stimulating electrical current emanates from the first electrode to stimulates tissue of the recipient, and the application of respective first electrical currents to the respective electrodes also corresponds to applying an electrical current to at least a second electrode of the respective electrodes such that a second stimulating electrical current emanates from the second electrode to stimulates tissue of the recipient;
- the obtaining of respective information on respective artifact voltages at the first location resulting from the respective stimulations is executed by:
- obtaining a first property of an electrical voltage resulting from the first stimulating electrical current at the at least one recording electrode at the first location;
- and
- obtaining a second property of an electrical voltage resulting from the second stimulating electrical current at the at least one recording electrode at the first location.
