Abstract
A method, including applying at first and second temporal locations respective electrical currents to an electrode located in a cochlea of a recipient, obtaining first and second data indicative of electrical properties at a plurality of locations away from the electrode, the first and second data corresponding to data obtained, respectively, at the first and second temporal locations, evaluating whether or not there is an existence of a temporal change in electrical conductivity between the electrode and the plurality of locations based on the obtained data, and determining whether or not a phenomenon exists inside the cochlea based on the evaluation.
Claims25
A method, comprising:
- applying at first and second temporal locations respective electrical currents to an electrode located in a cochlea of a recipient;
- obtaining first and second data indicative of electrical properties at a plurality of locations away from the electrode, the first and second data corresponding to data obtained, respectively, at the first and second temporal locations;
- and
- evaluating whether or not there is an existence of a temporal change in electrical conductivity between the electrode and the plurality of locations based on the obtained data, wherein
- the temporal change in electrical conductivity is a change in a spatial derivative of voltage between locations of the plurality of locations.
A method, comprising:
- applying an electrical current to an electrode located in a cochlea of a recipient;
- obtaining data, based on measurements, indicative of electrical properties at a plurality of locations away from the electrode;
- evaluating electrical conductivity between respective locations of the plurality of locations based on the obtained data to identify spatial derivatives between the respective locations of the plurality of locations;
- and
- determining whether or not a phenomenon exists in the recipient based on the identified spatial derivatives between the respective locations of the plurality of locations.
A method, comprising:
- applying an electrical current to an electrode located in a cochlea of a recipient;
- obtaining data indicative of electrical properties at a plurality of locations away from the electrode;
- and
- determining a spatial locational feature of the electrode within the cochlea relative to an anatomical structure of the cochlea based on a gradient of the obtained electrical properties, wherein
- the electrode is an electrode of an electrode array of a cochlear implant, and
- at least one of:
- (i) the spatial locational feature is a classification of the electrode array positioning from a group consisting of modiolar positioning, central positioning and lateral positioning;
- or
- (ii) the method further comprises:
- comparing the gradient to a database of gradients;
- and
- based on the comparison, determining a position of the electrode array relative to a modiolus of the cochlea based on a steepness of the gradient relative to gradients of the database of gradients.
