  • Patent number: 10052483
    Abstract: A cochlear implant sound processor including processor apparatus that, in response to being paired with a cochlear implant, converts audio signals from a microphone into stimulation data and transfer the stimulation data to cochlear implant, and in response to a failure to detect the cochlear implant, transfers the audio signals to a contralateral sound processor. Systems and methods are also disclosed.

  • Patent number: 10029096
    Abstract: An exemplary sound processor may 1) divide an audio signal into M analysis channels, 2) select only N analysis channels included in the M analysis channels for presentation to a patient during a stimulation frame, wherein N is less than M, 3) increase a probability that a particular analysis channel will be included in the N analysis channels selected for presentation to the patient during the stimulation frame if the particular analysis channel was not selected for presentation to the patient during one or more stimulation frames that temporally precede the stimulation frame, and 4) decrease the probability that the particular analysis channel will be included in the N analysis channels selected for presentation to the patient during the stimulation frame if the particular analysis channel was selected for presentation to the patient during the one or more stimulation frames that temporally precede the stimulation frame.

  • Patent number: 10016589
    Abstract: In one example, a cochlear lead includes a flexible body, an array of electrodes in the flexible body, and a plurality of wires passing along the array of electrodes. The plurality of wires includes a flexural geometry between each pair of adjacent electrodes and a substantially straight geometry over the electrodes. A method for forming an electrode array with a reduced apical cross section is also provided.

  • Patent number: 9993644
    Abstract: An exemplary fitting system 1) directs an EAS system to concurrently apply acoustic stimulation to a patient by way of a loudspeaker and electrical stimulation to the patient by way of an electrode located within a cochlea of the patient, 2) determines an interactive effect that the electrical stimulation has on the acoustic stimulation, 3) directs, if the fitting facility determines that the interactive effect is suppressive, the EAS system to use a first stimulation strategy that steers a current field produced by stimulation of the electrode away from intracochlear acoustic responders within the patient that are associated with the acoustic stimulation, and 4) directs, if the fitting facility does not determine that the interactive effect is suppressive, the EAS system to use a second stimulation strategy that steers the current field produced by the stimulation of the electrode towards the intracochlear acoustic responders.

  • Patent number: 9986349
    Abstract: A device includes a magnetic field source that generates a rotationally asymmetric magnetic field, a magnetic field sensor that generates a signal that is indicative of a position of the magnetic field sensor in the rotationally asymmetric magnetic field, and a processor coupled to the magnetic field sensor. The processor is configured to process the signal from the magnetic field sensor to control one or more operational settings of the medical device.

  • Patent number: 9973865
    Abstract: A prosthetic system, comprising a first sub-system configured to evoke a hearing percept based on a first principle of operation, and a second sub-system configured to evoke a hearing percept based on at least one of the first principle of operation or a second principle of operation different from the first principle of operation, wherein the first and second sub-systems are configured to independently process respective inputs indicative of an ambient sound to harmonize an estimated recipient perception of magnitude of a property of the respective evoked hearing percepts.
