Problems solved by technology

And because recipients may not always recognize facial nerve stimulation initially, or because recipients may not always be able to give reliable feedback, the final implant configuration may result in facial nerve stimulation

Abstract

The present application discloses systems and methods for detecting non-auditory nerve stimulation with an implant having a plurality of electrodes configured to electrically stimulate a target nerve of the implant recipient. One embodiment includes generating an electrical stimulation signal with a first set of electrodes of the implant, measuring a response to the electrical stimulation signal with a second set of electrodes of the implant, and determining whether the electrical stimulation signal stimulated at least one non-target nerve of the implant recipient based on the measured response.

Description

technical field Background technique [0001] A cochlear implant may provide a person with sensorineural hearing loss the ability to perceive sound by stimulating the person's auditory nerve via an electrode array implanted in the person's cochlea. The external components of the cochlear implant detect sound waves, which are converted into a series of electrical impulses that are delivered to the implant recipient's auditory nerve via an electrode array. Stimulating the auditory nerve in this way allows the cochlear implant recipient's brain to perceive hearing similar to the natural sense of hearing transmitted to the auditory nerve. [0002] One problem with using cochlear implants is that the electrodes may sometimes stimulate more than just the auditory nerve of the cochlear implant recipient. Implant recipients do not always recognize non-auditory nerve stimuli, or may not be able to reliably point to them (as in the case of child recipients or intellectually disabled re...
