Abstract: Presented herein are techniques for determining an estimated battery autonomy (e.g., estimated run-time) of a medical device having at least one actuator/transducer configured to mechanically stimulate a recipient. The medical device is specifically configured for the recipient and, as such, operates in accordance with a plurality of recipient-specific settings. The configuration of the medical device for the recipient (e.g., the plurality of recipient-specific settings), along with frequency and level current consumption characteristics of the medical device, are used to determine the estimated battery autonomy of the medical device. An environmental profile of the recipient can also be used with the configuration of the medical device for the recipient and the frequency and level current consumption characteristics of the medical device to determine the estimated battery autonomy.

Abstract: A vestibular stimulation prosthesis can restore vestibular function in recipients having vestibular deficiency. In an example, a body is appended onto or within the recipient's ossicular chain such that the body directly interfaces with an oval window of an inner ear of the recipient. Electrical stimulation is provided using one or more electrodes of the body to stimulate the vestibular system and thereby restore vestibular functioning. In an example, a stimulator device connected to the body via a lead is also implanted. The stimulator device can have a small and convenient form factor. In some instances, the stimulator device is a stand-alone device that is configured to provide stimulation to the recipient's vestibular system without respect to signals received from devices external to the recipient. In some implementations, the stimulator device is a component of a sensory prosthesis (e.g., a cochlear implant or bionic eye) or another medical device.

Abstract: Presented herein are techniques to control the spread of current beyond, in an apical direction, a predetermined location/point in the cochlea. As a result, the techniques presented herein create a protected apical zone at an apical side of the predetermined location for undisturbed acoustic temporal coding (i.e., an apical region of the cochlea in which the voltage fields from delivered current signals are nulled, minimized, or otherwise controlled in order to eliminate, reduce, or otherwise limit electro-acoustic interactions that could negatively affect remaining low-frequency hair cells).

Abstract: A vestibular stimulation array is disclosed having one or more separate electrode arrays each operatively adapted for implantation in a semicircular canal of the vestibular system, wherein each separate electrode array is dimensioned and constructed so that residual vestibular function is preserved. In particular, the electrode arrays are dimensioned such that the membranous labyrinth is not substantially compressed. Furthermore, the electrode array has a stop portion to limit insertion of the electrode array into the semi-circular canal and is still enough to avoid damage to the anatomical structures.
