Both portions include an associated coil that transmits a signal between the two portions. The external coil has a form factor substantially similar to the implantable coil. This form factor allows the external portion to be manufactured with a smaller footprint, since components that may otherwise interfere with signal transmission (e.g., batteries) may be installed closer to the external coil.

    Abstract: Arrangements are described for assessing potential fitting processes for a cochlear implant patient. A test stimulation sequence at a given test frequency is delivered to the cochlear implant patient. The test stimulation sequence includes jittered stimulation periods when the test frequency varies due to a jitter variation component, and unjittered stimulation periods when the test frequency is constant without a jitter variation component. At least two different responses of the cochlear implant to the test stimulation sequence are measured in parallel. The different responses include an objective electrophysiological response, and a subjective psychophysical response. A correlation between the different responses is evaluated to determine an appropriate fitting process for the cochlear implant patient.

The IR light provides optical stimulation of nerves to generate nerve-action potentials (NAPs) in one or more individual nerve cells, and/or compound nerve-action potentials (CNAPs) in a nerve bundle. In some embodiments, the stimulation of NAPs and CNAPs is used to restore hearing. In some embodiments, the broad wavelength profile extends the physical volume of tissue that is stimulated, thus homogenizing the spatial light-absorption profile of the stimulation light used, e.g., for optical triggering of NAPs and CNAPs in the cochlea.

  • Patent number: 8965518
    Abstract: The invention relates to a device for applying a transcutaneous electrical stimulation stimulus to the surface of a section of the human ear, which comprises a retaining element which is mountable on or in the ear and a number of electrodes which are arranged on or in an electrode carrier, wherein the device comprises a control apparatus which controls or regulates the generation of a potential difference between the electrodes. In order to permit an improved and safer transcutaneous stimulation the invention proposes that at least three electrodes are arranged on or in the electrode carrier, wherein the at least three electrodes are located in one plane, wherein the position of at least one of the at least three electrodes is adjustable on the electrode carrier and wherein the at least one electrode of which the position is adjustable is mounted such as to be displaceable in a translational manner in the plane. Furthermore, the invention relates a method for the operation of such a device.

  • Patent number: 8954159
    Abstract: Fitting a multi-channel cochlear implant system to an implanted patient is described. A fit map database is accessed that contains parameter data from fit maps of previously measured cochlear implant patients. For subsets of signal channels in each fit map, an average deviation is established between estimated parameter values and measured parameter values across signal channels not in a given subset based on measured parameter values of signal channels in the given subset. For a given number of signal channels, a subset of the same number of signal channels is identified that has a minimum average deviation. Then fit parameters for signal channels in the identified subset are measured and fit parameters for the remaining signal channels not in the identified subset are estimated.

  • Patent number: 8948877
    Abstract: A system and method for activating stimulation electrodes in cochlear implant electrode is described. A preprocessor filter bank is configured to process an input acoustic audio signal to generate band pass signals that each represent an associated band of audio frequencies. An information extractor is configured to extract stimulation signal information from the band pass signals based on assigning the band pass signals to corresponding electrode stimulation groups that each contain one or more stimulation electrodes, and generates a set of stimulation event signals for each electrode stimulation group that define electrode stimulation timings and amplitudes. A pulse selector is configured to select a set of electrode stimulation signals from the stimulation event signals based on a pulse weighting function that uses channel-specific weighting factors favoring lower frequencies for activating the stimulation electrodes to stimulate neighboring audio nerve tissue.

  • Patent number: 8938304
    Abstract: A cochlear implant system has an implantable portion that includes a stimulator module for producing for the auditory system of a user an electrical stimulation signal representative of an acoustic signal. The implantable portion further includes a battery for supplying power to the stimulator module, a receiver module for receiving an electrical power signal across the skin of a user, and a recharge module that uses the electrical power signal to recharge the battery. The recharge module recharges the battery at less than the maximum recharge rate.

  • Patent number: 8923535
    Abstract: Disclosed is hearing device that uses magnetostrictive materials to assist a user in hearing and comprehending sounds. Conductive coils are made with a magnetostrictive covering that can comprise a film or other coating. In addition, printed circuit boards can be used with traces that form a coil to generate a magnetic field that activates a magnetostrictive film disposed over the coil traces on the printed circuit board. Enhanced effects are achieved using these systems. Delays in the signal processing can also be introduced by varying the thickness of the magnetostrictive coverings.
