Abstract: The present technology is directed to vestibular prostheses and associated systems and methods. In several embodiments, for example, a vestibular prosthesis includes an external rotational sensor configured to receive velocity and orientation information. The prosthesis further includes an external processor configured to convert the velocity and orientation information into an audio signal. The audio signal is sent to a cochlear implant, which applies stimulation to a semicircular ear canal in response to receiving the audio signal. In some embodiments, the processor and cochlear implant communicate in real time via an inductive link.

Abstract: A vestibular implant comprising a stimulation unit to generate electric stimuli and deliver to electrode arrays is disclosed. The stimulation unit generates electric stimuli in response to a user input or continuously generates electrical stimuli. The electrode arrays comprise electrodes and are adapted for placement within a semicircular canal of an ear. The electric stimuli is delivered from the stimulation unit to the electrode so that the electrodes apply electric stimuli. A predetermined electric stimulus is applied to restore spontaneous vestibular activity during a Meniere's attack. A continuous, unmodulated electric stimulus is applied to suppress the symptoms of unilateral loss of vestibular function. Additionally, the electrodes record electrically evoked compound action potentials (eCAP). An appropriate location for the placement of the electrode array is determined based on the recorded eCAP.
