Abstract

A system including a galvanic stimulator, and an eye tracking device, wherein the system is a clinical vestibular implant suitability evaluation system. The system includes a computing apparatus configured analyze eye tracking data generated by the eye tracking device and provide output indicative of the analysis. The system is configured to evoke a vestibular reflex in a human with at least a partially functioning neural system of the human's vestibular system.

Claims (43)

1 . A system, comprising:

a galvanic stimulator; and

an eye tracking device, wherein

the system is a clinical vestibular implant suitability evaluation system,

the eye tracking device includes a videonystagmography recording sub-system, and

the system further comprises a vestibular evoked myogenic potentials (VEMPs) sub-system configured to record vestibulo-ocular and/or vestibulo-spinal reflex(es).

2 . The system of claim 1 , further comprising:

a computing apparatus configured to analyze eye tracking data generated by the eye tracking device and provide output indicative of the analysis.

3 . The system of claim 1 , further comprising:

a computing apparatus configured to analyze eye tracking data generated by the eye tracking device and, based on the analysis, automatically provide an indication of whether a vestibular implant would be utilitarian for a human stimulated by the galvanic stimulator and who's eyes are tracked by the eye tracking device.

4 . The system of claim 1 , wherein:

the system is established by a head-worn apparatus.

5 . The system of claim 1 , wherein:

the system is configured to electrically evoke a vestibular reflex in a human with at least a partially functioning neural system of the human's vestibular system.

6 . The system of claim 1 , wherein:

the system is established in part by a head-worn apparatus and is established in part by a computing apparatus separate from the head-worn apparatus.

7 . The system of claim 1 , wherein:

the system is configured to automatically obtain data indicative of a response to stimulation by the galvanic stimulator applied to a person.

8 . The system of claim 7 , wherein:

the system is configured to automatically evaluate the obtained data; and

the obtained data includes vision related data, wherein the evaluation of the obtained data includes determining a degree of peripheral vestibular response that occurs based on the stimulation by the galvanic stimulator applied to the person.

9 . The system of claim 7 , wherein:

the obtained data is eye movement data that is temporally correlated with the stimulation applied by the galvanic stimulator.

10 . The system of claim 7 , wherein:

the system is configured to automatically evaluate the obtained data; and

the system is configured to automatically determine a viability of the person for the vestibular implant based on the evaluation of the obtained data.

11 . The system of claim 7 , wherein:

the system is configured to automatically determine that there is a lack of response to stimulation by the galvanic stimulator applied to the person.

12 . The system of claim 11 , wherein:

the system is configured to automatically identify an adjustment to an electrical stimulation regime implemented by the system using the galvanic stimulator based at least on the determination that there is a lack of response to the stimulation applied by the galvanic stimulator applied to the person.

13 . The system of claim 1 , wherein:

the system is configured to apply stimulation to both inner ears of a person at different times.

14 . An assembly, comprising: electrodes; an electrode stimulator in signal communication with the electrodes, the electrode stimulator configured to generate an electrical current, which is provided to the electrodes sufficient to effectively stimulate a nervous system of a human from a location on a surface of skin of the human that evokes a response related to an ocular motor system of the human; and an eye tracking subassembly and/or an electrical potential sensor subassembly, wherein the assembly is configured to develop reflex data using the subassembly that is correlated with data indicative of stimulation provided by the electrodes, and system is established in part by a head-worn apparatus and is established in part by a computing apparatus separate from the head-worn apparatus.

15 . The assembly of claim 14 , wherein the assembly includes the eye tracking subassembly, and wherein the eye tracking subassembly includes a videonystagmography recording device.

16 . The assembly of claim 14 , wherein the assembly includes the electrical potential sensor subassembly, and wherein the electrical potential sensor subassembly is a vestibular evoked myogenic potentials (VEMPs) sub-system configured to record vestibulo-ocular and/or vestibulo-spinal reflex(es).

17 . The assembly of claim 14 , wherein:

the electrode stimulator is configured to generate the electrical current, which is provided to the electrodes sufficient to effectively stimulate a vestibular system of the human from the location on the surface of skin of the human; and

the assembly is configured to develop eye tracking data using the eye tracking subassembly that is correlated with the data indicative of stimulation provided by the electrodes.

18 . The assembly of claim 17 , wherein:

the assembly is configured to excite a synapse between vestibular hair cells of a human and an eighth nerve afferents to evoke an eye movement, the eye-tracking subassembly being configured to detect the movement of the eye.

19 . The assembly of claim 14 , further comprising:

a dedicated software/hardware/firmware suite configured to receive data indicative of eye movement(s) detected by the eye-tracking sub-assembly and output data based on the received data; and

the dedicated software/hardware/firmware is configured to evaluate the received data and determine a suitability of a vestibular implant of a human whose eye movements the data received is based.
