摘要： An illustrative insertion management system may be configured to provide, as a first input to a machine learning model, geometric model data specific to a recipient of a cochlear implant and representative of a geometrical model of a cochlea of the recipient, provide, as a second input to the machine learning model, procedure data representative of one or more contextual attributes of a lead insertion procedure in which an electrode lead is inserted to the cochlea of the recipient, and generate, based on an output of the machine learning model that takes into account the geometric model data and the procedure data, procedure assistance data configured to assist a user in performing the lead insertion procedure.

摘要： A stapedius reflex threshold determination system directs a cochlear implant and a loudspeaker to apply a first electro-acoustic stimulation event to a patient, and determines that a first evoked response that occurs within the patient in response to the first electro-acoustic stimulation event has a level within a predetermined threshold amount of a baseline evoked response level. Based on that determination, the system detects that a stapedius reflex within the patient is not triggered. The system also directs the cochlear implant and the loudspeaker to apply a second electro-acoustic stimulation event to the patient, and determines that a second evoked response that occurs within the patient in response to the second electro-acoustic stimulation event has a level at least the predetermined threshold amount lower than the baseline evoked response level. Based on this determination, the system detects that the stapedius reflex within the patient is triggered.

摘要： An exemplary system is configured to maintain data representative a machine learning model for use in a cochlear implant system and train the machine learning model. The training may include applying audio content as a training input to the machine learning model, the machine learning model configured to apply a machine learning heuristic to the audio content to output an electrical signal representative of the audio content; applying the electrical signal to a brain processing model, the brain processing model configured to output synthesized audio content representative of the electrical signal; generating an error metric representative of a difference between the audio content and the synthesized audio content; and feeding back the error metric into the machine learning model, the machine learning model configured to use the error metric to adjust the machine learning heuristic applied to the audio content.

摘要： A system includes electronic circuitry that receives a self-clocking differential signal comprising a data signal encoded with a clock signal at a dock frequency. The electronic circuitry is configured to recover, from the self-docking differential signal, the data signal and the dock signal. Then, based on the recovered dock signal, the electronic circuitry is configured to wirelessly transmit, to an implantable stimulator implanted within a recipient, a forward telemetry signal representing data recovered from the data signal. Corresponding systems, methods, devices, and application specific integrated circuits (ASICs) are also disclosed.

摘要： An exemplary cochlear implant system for use by a recipient includes a microphone assembly and an off-the-ear (OTE) sound processor communicatively coupled with the microphone assembly. The microphone assembly includes a microphone configured to capture an audio signal representative of sound presented to the recipient, and a retention device configured to hold the microphone in place near an entrance to an ear canal of an ear of the recipient. The OTE sound processor includes a housing configured to be worn on a head of the recipient at a location that is off the ear of the recipient, and electronic circuitry included within the housing. The electronic circuitry is configured to generate stimulation parameters that, when transmitted to a cochlear implant implanted within the recipient, direct the cochlear implant to apply electrical stimulation representative of the captured audio signal to the recipient. Corresponding systems and methods are also disclosed.
