Patent
Advanced Bionics | Date: 2017-01-25

A system includes a sound processor included in an electro-acoustic stimulation (EAS) device configured to direct a cochlear implant to apply electrical stimulation to a patient and a receiver to apply acoustic stimulation to the patient. The system further includes a volume control facility and a selection facility configured to selectively associate the volume control facility with the electrical stimulation in response to a first user input, selectively associate the volume control facility with the acoustic stimulation in response to a second user input, and selectively associate the volume control facility with both the electrical stimulation and the acoustic stimulation in response to a third user input.

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.

A headpiece for use with a cochlear implant including a headpiece housing, a retention magnet within the headpiece housing that generates a retention magnetic field, the retention magnet including a bottom surface that faces the cochlear implant, a top surface opposite the bottom surface, and an outer radial surface between the top and bottom surfaces, an induction coil within the headpiece housing that transmits audio signals to the cochlear implant by generating a telemetry magnetic field, and a retention flux guide within the headpiece housing and adjacent to the top surface of the retention magnet.

A system for retaining a magnet in a cochlear implant, comprising a retainer embedded within an encapsulant of the cochlear implant, and a magnet case engaged with the retainer. A retainer for retaining a magnet within a cochlear implant comprising a number of first fasteners that couple with a number of corresponding second fasteners of a magnet case hermetically sealing the magnet, and a number of supports embedded within an encapsulant of the cochlear implant.


An exemplary system includes an electro-acoustic stimulation (EAS) device, a cochlear implant, an electrode lead comprising a plurality of basal electrodes configured to be disposed within a basal region of a cochlea of a patient and a plurality of apical electrodes configured to be disposed within an apical region of the cochlea; and a loudspeaker communicatively coupled to the EAS device. The EAS device is configured to operate in an EAS mode by 1) disabling the apical electrodes for standard electrical stimulation, 2) detecting, while the apical electrodes are disabled for standard electrical stimulation, audio content presented to the patient and included in an acoustic stimulation frequency range, 3) directing the loudspeaker to apply acoustic stimulation representative of the audio content included in the acoustic stimulation frequency range to the patient, and 4) periodically directing the cochlear implant to apply conditioning stimulation by way of the disabled apical electrodes.


The stimulation provided in the electrically stimulated cochlea is modulated in accordance with the amplitude of a received acoustic signal and the onset of a sound in a received acoustic signal to provide increased sound perception. An onset time that corresponds to the onset of a sound is detected in an acoustic signal associated with a frequency band. A forcing voltage and a transmitting factor are determined, wherein the forcing voltage and the transmitting factor are associated with the frequency band at the detected onset time. The acoustic signal is modulated as a function of the forcing voltage and the transmitting factor to generate an output signal. The generated output signal can be used to stimulate the cochlea. The modulation strategy can be used in conjunction with sound processing strategies that employ frequency modulation, amplitude modulation, or a combination of frequency and amplitude modulation.

A hearing aid including a permanent magnet to be fixed at a patients incus (26), an audio signal source (14), an audio signal processing unit (16) for processing audio signals from the audio signal source, a driver unit (18) including a coil (22) for generating a magnetic field (25) that vibrates the permanent magnet according to the processed audio signals in order to stimulate the patients hearing, and a measurement arrangement (56, 58, 60) for measuring the magnetic coupling between the coil and the permanent magnet in order to adjust the position of the coil or the input signals to the coil provided by the driver unit.


An exemplary system includes a data program loading facility configured to pre-load program data representative of a plurality of sound processing programs onto a sound processor during a data transfer session and a fitting facility selectively and communicatively coupled to the data program loading facility and configured to selectively use one or more of the pre-loaded sound processing programs to fit the sound processor to a cochlear implant patient after completion of the data transfer session.
