摘要： Apparatus, systems, and methods having or using an improved implantable middle ear transducer for driving an ossicular chain bone to assist in aiding hearing. One embodiment of the present invention is a transducer assembly for converting electrical signals to mechanical vibrations which can be coupled, for example, to the stapes to provide audible frequency vibrations to the cochlea. One transducer assembly includes a pair of fins or gussets coupled to opposite sides of a transducer in the direction of unwanted movement of the transducer. The base of the transducer may be coupled to a base member while the fins have free edges that are near to but not coupled to the base member. Some fins are triangular shaped. The fins may not substantially inhibit vibration in the preferred plane, but can inhibit unwanted vibrations in a plane orthogonal to the preferred direction which can substantially include a plane containing the fins.

摘要： Embodiments of the invention provide an amplifier including a gain control circuit having a gain measurement circuit as part of a feedback loop. The gain measurement circuit generates an attenuated output signal, based on the gain of the amplifier circuit, which is used to generate a gain control signal. One amplifier includes a first attenuator enabling primary compression and a second attenuator as part of a gain measurement circuit. In some cases the attenuation factors of the first and second attenuators may be proportional or substantially the same. In some embodiments one or more output stages (e.g., differential amplifiers) are provided to generate the gain control signal based on differential combinations of an audio output, the attenuated output signal, and a primary threshold signal. A ratio of the gains of the two or more comparing amplifiers can set a primary compression ratio in some cases.

摘要： A driver and sensor assembly that is hermetically sealed so that the assemblies may be fully implanted in a being. The assemblies employ a transducer that has a longitudinal axis and that vibrates or picks up vibration in a direction substantially transverse to its longitudinal axis. A sheath covers the transducer and is hermetically sealed to a housing. Leads from a sound processor are coupled to the housing and the entire assembly is hermetically sealed.

摘要： Cochlear implant systems can comprise a cochlear implant system comprising a cochlear electrode, a stimulator in electrical communication with the cochlear electrode, a return electrode, and one or more controllers. The cochlear electrode can include a first contact electrode and the stimulator can include a first source element in electrical communication with the first contact electrode. The one or more controllers can be configured to cause the stimulator to emit a predetermined current from the first source element to the return electrode via a first current path and determine a first voltage at the first contact electrode and a second voltage at the return electrode. The one or more controllers can determine an impedance associated with the first current path and determine one or more stimulation parameters, such as a compliance voltage for sourcing a prescribed current, for the source element based on the determined impedance.

摘要： 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.

摘要： 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.

摘要： A cochlear implant system can comprise an input source configured to receive a stimulus and generate an input signal representative of the stimulus, a cochlear electrode, a stimulator in communication with the cochlear electrode configured to provide electrical stimulation to cochlear tissue via the cochlear electrode, and a signal processor programmed with a first pulse rate. The signal processor can be configured to receive the input signal from the input source and filter the input signal based on the first pulse rate such that one or more frequencies associated with the first pulse rate in the received input signal are attenuated. The signal processor can further be configured to output a stimulation signal to the stimulator based on the filtered input signal with the stimulation signal causing the stimulator to provide electrical stimulation to the cochlear tissue at the first pulse rate.

摘要： 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.

摘要： Cochlear implant systems can include a cochlear electrode and a stimulator in electrical communication with the cochlear electrode. The stimulator can be in communication with a controller, which is in communication with a testing circuit and a switching network. The stimulator can include a plurality of source elements. The controller can control the switching network to place the plurality of source elements into communication with the testing circuit. The controller can further cause one of the plurality of source elements to emit an electrical current and can determine an amount of electrical current emitted from the source element using the testing circuit. The controller can compare the determined amount of electrical current emitted by the source element with a prescribed current. The controller can adjust the output of each of the plurality of source elements based on the determined amount of electrical current emitted by the stimulator.
