The present disclosure relates to compact hearing aids, components thereof, and support systems therefor, as well as methods of insertion and removal thereof. The compact hearing aids generally include a sensor, such as a microphone, an actuation mass, an energy source for providing power to the compact hearing aid, a processor, and an actuator enclosed in a housing that is designed to be inserted through the tympanic membrane during a minimally-invasive outpatient procedure. In operation, the microphone receives sound waves and converts the sound waves into electrical signals. A processor then modifies the electrical signals and provides the electrical signals to the actuator. The actuator converts the electrical signals into mechanical motion, which actuates the actuation mass to modulate the velocity or the position of the tympanic membrane.

A system includes a unit for capturing ECAP signals induced at electrodes of an electrode array in response to stimulation of a cochlea by applying auditory nerve stimulation signals to the electrodes; a memory unit for storing the captured ECAP signals and/or ECAP data derived from the captured ECAP signals; an electrode migration detection unit for detecting electrode migration relative to the cochlea by comparing presently captured ECAP signals and/or ECAP data derived from such presently captured ECAP signals to stored previously captured ECAP signals and/or ECAP data derived from such previously captured ECAP signals; and a unit for outputting an alarm signal in case that electrode migration is detected by the electrode migration detection unit.

An earpiece includes an earbud that supports at least one electrode, and an ear tip that includes a hydrogel. The ear tip is configured to be coupled to the earbud such that the hydrogel overlies the at least one electrode and such that the hydrogel is disposed between the at least one electrode and the user's skin when the earpiece is worn.

An external auditory canal therapy device may include a housing inserted into an external auditory canal of a human ear, at least one electrically conductive electrode coupled to the housing and one or both of at least one irradiation source and at least one speaker coupled to the housing. An electrical circuit carried by the housing may control the at least one electrically conductive electrode to provide electrically stimulation through the dermis to at least one of an arterial branch and a peripheral nerve branch of at least one cranial nerve, and may control one or both of the at least one irradiation source to irradiate the at least one of the arterial branch and the peripheral nerve branch of the at least one cranial nerve through the dermis and the at least one speaker to produce acoustic waves directed toward a tympanic membrane of the ear.

A method for assessing a patient's suitability for receiving a vagus nerve stimulation therapy includes receiving a criterion regarding the patient's suitability for receiving a vagus nerve stimulation therapy; controlling a stimulation device to provide stimulation to a vagus nerve of the patient; receiving, from a sensor, response data indicative of a physiological response of the patient to the stimulation of the vagus nerve; and determining the patient's suitability for receiving the vagus nerve stimulation therapy based on the criterion and the physiological response of the patient to the stimulation.

The present invention provides in part wearable devices for balance control. The wearable devices are capable of non-invasively monitoring and stimulating the wearer's vestibular system such that it produces postural responses. The wearable devices deliver low levels of electrical current to the vestibular system of a user to maintain balance. In one example, the wearable device is in the form of a pair of glasses.

Disclosed herein are an electrode assembly, an in-ear headphone, an in-ear headphone pair, and an electrode pair assembly, each for non-invasive vagus nerve stimulation. Each of the foregoing items includes a first electrode and a second electrode. An electrode assembly configured for insertion into an ear of a user includes a first electrode, a second electrode, and a shim positioned therebetween. An in-ear headphone or headphone pair may include the electrode assembly with a housing and a waveform generator. An electrode pair assembly may include a first electrode configured for insertion into a first ear of a user, and a second electrode configured for insertion into a second ear of the user. Certain embodiments further include audio components positioned within a housing of at least one in-ear headphone to deliver audio stimulation through a central channel of a first electrode or second electrode, respectively.

Disclosed examples include technology to use residual vestibular function or residual vestibular nerve function of a recipient to provide low frequency information to enhance auditory percepts caused by auditory prostheses. An example can include adding a low frequency actuator to a cochlear implant for placement close to the vestibule of the ear. In addition or instead, one or more electrodes can be disposed proximate the vestibule of the ear to electrically stimulate residual vestibular function provided by, for example, the utricle and saccule. The stimulation provided by these components can be optimized for delivery to the vestibular system.
