Sound processors and systems including sound processors are disclosed.


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.

Apparatus and methods for converting one type of speech processor unit into another type of speech processor unit.


An exemplary sound processor included in a cochlear implant system comprises a control facility that represents a first frequency domain signal to a patient by 1) directing a cochlear implant included in the cochlear implant system to apply, during a first stimulation frame, a first monophasic stimulation pulse representative of a first temporal portion of the first frequency domain signal that corresponds to the first stimulation frame, the first monophasic stimulation pulse having a first polarity, and 2) directing the cochlear implant to apply, during a second stimulation frame that is temporally subsequent to the first stimulation frame, a second monophasic stimulation pulse representative of a second temporal portion of the first frequency domain signal that corresponds to the second stimulation frame, the second monophasic stimulation pulse configured to at least partially charge balance the first monophasic stimulation pulse and having a second polarity opposite the first polarity.

A method for sterile packaging of a surface modified implantable device includes irradiating a surface of the device such that the hydrophobicity of the surface is decreased and, optionally, the device is simultaneously sterilized. The surface of the sterile, surface-modified implantable device is then covered in a polar solution to prevent hydrophobic recovery of the surface.

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
Advanced Bionics | Date: 2016-05-17

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.
