Abstract: An apparatus includes an enclosure containing a hermetically sealed region, the enclosure configured to be implanted on or within a recipient. The apparatus further includes circuitry within the hermetically sealed region and configured to generate signals. The apparatus further includes at least one heating element configured to receive the signals and to generate heat in response to the signals. The apparatus further includes at least one flow control element outside the hermetically sealed region and configured to respond to the heat by controlling a flow of liquid through at least one cannula to controllably administer the liquid internally to the recipient.

Abstract: An apparatus includes first circuitry configured to be implanted on or within a recipient's body and to apply stimulation signals to at least one muscle of a recipient and/or to at least one neuron configured to control the at least one muscle. The apparatus further includes second circuitry configured to be implanted on or within the recipient's body and configured to wirelessly receive electrical power from a power source external to the recipient's body and to provide at least a portion of the received electrical power to the first circuitry. The second circuitry includes a plurality of coils, each coil of the plurality of coils having at least one electrically conductive conduit encircling a center axis of the coil. The coils are configured to be implanted on or within the recipient's body with different orientations and/or positions relative to one another.

Abstract: An apparatus includes a housing having an external surface configured to be placed on a non-magnetic material over-laying a first device comprising a first ferromagnetic or ferrimagnetic material. The apparatus further includes a second ferromagnetic or ferrimagnetic material and/or an electromagnet within the housing. The second ferromagnetic or ferrimagnetic material and/or the electromagnet is configured to generate an attractive magnetic force with the first device. The apparatus is configured to controllably adjust an attractive magnetic force between the first device and the second ferromagnetic or ferrimagnetic material and/or the electromagnet along a longitudinal axis substantially perpendicular to the surface.

Abstract: Presented herein are dissolution barriers for use with tissue-stimulating prostheses. As described further below, a tissue-stimulating prosthesis comprises a stimulating assembly including an elongate insulating carrier member and a plurality of electrode contacts disposed along the carrier member. A continuous dissolution barrier is disposed on the surface of the stimulating assembly so as to substantially encapsulate/enclose the plurality of electrode contacts and the carrier member. The continuous dissolution barrier is configured to inhibit in situ dissolution of the plurality of electrode contacts.

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: A method includes receiving first information regarding a pose of a structure in a first time period. The structure is configured to be inserted into a body portion of a recipient. The first information includes at least one of: a first estimate of the pose of the structure in the first time period, and a first measurement set including one or more first measurement values. At least some of the one or more first measurement values are generated using a plurality of sensors distributed along the structure. The one or more first measurement values are indicative of the pose of the structure in the first time period. The method further includes generating a second estimate of the pose of the structure using at least the first information and a probabilistic model of the structure and/or the body portion.

Abstract: An apparatus includes an actuator configured to generate vibrations. The actuator includes a substantially planar piezoelectric oscillator having a central portion substantially surrounding and in mechanical communication with a coupling portion and a peripheral portion spaced from the coupling portion. The piezoelectric oscillator is configured to undergo bending oscillations in response to received electric voltage signals. The actuator further includes at least one mass configured to move in response to the bending oscillations of the piezoelectric oscillator. The actuator further includes at least one coupler configured to allow expansion and contraction of the peripheral portion along a first direction substantially parallel to the piezoelectric oscillator and to inhibit movement of the peripheral portion relative to the at least one mass along a second direction substantially perpendicular to the piezoelectric oscillator.
