Abstract: Cochlear implant systems can include first and second subsystems, each subsystem including an input source, a signal processor, a stimulator, and a cochlear electrode. A single implantable battery and/or communication module can provide power to and communicate with each subsystem, such as via each signal processor. Systems can include separate leads providing separate communication between the implantable battery and/or communication module and each subsystem, or can include a bifurcated lead providing signals to both subsystems simultaneously. The implantable battery and/or communication module can be configured to output addressed signals designating for which subsystem a signal is intended. The implantable battery and/or communication module can be configured to separately update settings associated with each respective subsystem, such as a transfer function associated with each signal processor.

Abstract: Cochlear implant systems can comprise a cochlear implant system comprising a cochlear electrode, a stimulator, an input source, and an implantable battery and/or communication module. The signal processor may be programmed with a transfer function and be configured to receive input signals from the input source and output a stimulation signal to the stimulator based on the received input signals with the transfer function. The system may be configured to receive a status indicator signal indicative of whether an external auditory aid device is active and update the transfer function of the signal processor if the external auditory aid device is active. For example, the signal processor can operate programmed with a first transfer function if the external auditory aid device is not active and with a second transfer function if the external auditory aid device is active.

Abstract: Cochlear implant systems can include a cochlear electrode, a stimulator in electrical communication with the cochlear electrode, a sensor configured to receive a stimulus signal and generate an input signal based on the received stimulus signal, and a signal processor in communication with the stimulator and the sensor. The signal processor can include an analog filtering stage configured to generate an analog filtered signal from a received input signal and a digital filtering stage configured to generate a digitally filtered signal from the analog filtered signal. The analog filtering stage and digital filtering stage can be used to normalize the frequency response of the digitally filtered signal with respect to the stimulus signal.

Abstract: Cochlear implant systems can include an inner ear sensor configured to receive a stimulus signal from the cochlear tissue of a wearer and generate an input signal based on the received stimulus signal. The inner ear sensor can be configured to detect pressure, for example, within a wearer's cochlear tissue and generate an input signal based on the detected pressure. The inner ear sensor can be integrated with a cochlear electrode implanted in the cochlear tissue. Systems can include a signal processor programmed with a transfer function and configured to receive an input signal and output a stimulation signal based on the received input signal and transfer function. Systems can include an implantable battery and/or communication module in communication with the signal processor. The implantable battery and/or communication module can be configured to interface with and update the transfer function of the signal processor.

Abstract: Fully implantable cochlear implant systems can include a cochlear electrode, a stimulator in electrical communication with the cochlear electrode, a signal processor in communication with the stimulator, and an implantable battery and/or communication module in communication with the signal processor. A cochlear implant network can include an external device in wireless communication with the fully implantable cochlear implant system via one or more system components, such as the implantable battery and/or communication module, the stimulator, and/or the signal processor. The external device can be configured to wirelessly communicate signals to the fully implantable cochlear implant system such as control signals and/or audio signals. Networks can include a plurality of external devices capable of interfacing with one or more implantable components of a fully implantable cochlear implant system.

Abstract: A hearing aid is disclosed, which, in a test mode, can determine the impedance of the transducer that stimulates the anatomy of the patient. Impedance may be determined by simultaneous determination of the current flowing through the transducer and the voltage across the transducer. In some cases, the output amplifier of the hearing aid includes two outputs, with one being a scaled and/or summed replica of the other. The amplifier is driven with a periodic signal with a particular frequency and a known peak voltage. The periodic signal may be sinusoidal. The primary output of the amplifier is electrically connected to the transducer, with a known current given by the peak input current and a known gain of the amplifier. The voltage from the secondary output of the amplifier is measured. The impedance is calculated by dividing the measured voltage from the secondary output of the amplifier by the known current.

Abstract: A cochlear implant and analysis system includes a stimulator, an input source, a signal processor, a wireless communication interface, and an external device. The system can receive an acoustic stimulus, generate an input signal representative thereof, and apply a transfer function to the input signal to generate and output a stimulation signal to the stimulator. The signal processor can receive an analysis input indicating a first signal for analysis and generate an analysis signal based on the received analysis input. The first signal can be an input signal from an input source or a result of one or more processing steps. The signal processor can output the analysis signal to the wireless communication interface with the wireless communication interface configured to output a signal representative of the analysis signal to an external device.

Cochlear implant systems can further comprise a removable earplug comprising a sensor, a second near field communication interface, and a signal processor. The removable earplug can be inserted into an ear canal to align the first and second near field communication interfaces. Once aligned, the battery can provide electrical power to the removable earplug via the near field communication interfaces. The signal processor can receive input signals from the sensor of the removable earplug and generate a stimulation signal representative of the auditory signals. The signal processor can communicate the stimulation signal to the stimulator via the near field communication interfaces.
