Abstract
A method, including energizing one or more electrodes of a cochlear electrode array to induce a current flow in the cochlea at a plurality of temporal locations, measuring one or more electrical properties at one or more locations in the cochlea resulting from the induced current flow at the plurality of different temporal locations and determining whether or not trauma has occurred based on a change between the measured electrical properties from the first temporal location to the second temporal location.
Claims24
A method, comprising:
- energizing one or more electrodes of a cochlear electrode array to induce a current flow in the cochlea at a plurality of temporal locations;
- measuring one or more electrical properties at one or more locations in the cochlea resulting from the induced current flow at the plurality of different temporal locations;
- determining whether or not trauma has occurred based on a change between the measured one or more electrical properties from a first temporal location to a second temporal location of the plurality of different temporal locations;
- and
- at least one of:
- a. analyzing the change in the measured one or more electrical properties to identify indications of blood in the cochlea and upon a determination that an indication that blood in the cochlea is present, determining that trauma has occurred;
- or
- b. analyzing the change in the measured one or more electrical properties to identify indications of a clot in the cochlea and upon a determination that an indication that a clot in the cochlea is present, determining that trauma has occurred.

A method, comprising:
- causing current to flow from a first electrode of an intra-cochlea electrode array to a second electrode of the intra-cochlea electrode array at a plurality of temporal locations;
- measuring, at a third electrode and a fourth electrode of the intra-cochlea electrode array, respective voltages induced by the flowing current at the plurality of temporal locations;
- determining that a change between the voltage measurements at the third electrode and the fourth electrode has occurred between the temporal locations;
- determining a time period between the temporal locations;
- and
- determining whether or not a phenomenon has occurred within the cochlea based on the determined time period.
3 more elements
A method, comprising:
- applying at first and second temporal locations respective electrical currents to one or more electrodes located in a cochlea of a recipient;
- obtaining first and second data indicative of an electrical property at a location within the cochlea, 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 the electrical property within the cochlea at the location based on the obtained data;
- and
- determining whether or not there is blood and/or a clot in the cochlea based on the temporal change in the electrical property.
