Abstract: Implantable medical devices and instruments (tools) including one or more implantable sensors. In certain embodiments, a hearing prosthesis comprises an implantable stimulating assembly configured to be implanted in a recipient's cochlea. At least one implantable sensor is disposed in the implantable stimulating assembly and is configured to monitor an insertion attribute.

Abstract: The present invention provides for fitting a multimodal hearing system to a recipient. Such fitting may include determining a desired perception for an input signal, receiving a measurement of a perception evoked by applying to the recipient one or more stimulation signals that correspond to the input signal, wherein the one or more stimulation signals applied using two or more stimulation modes, and each stimulation signal is determined using stimulus mode weighting, and adjusting one or more of the stimulus mode weightings based on the difference between the measured evoked perception and the desired perception. A multimodal hearing system is able to stimulate using an acoustic, electrical, mechanical mode and/or photo effect mode.

Abstract: A cochlear prosthesis comprising an electrical signal analyser configured to process a first frequency sub-range of a detected sound signal for electric stimulation of the cochlea, and a delay circuit configured to impose a delay on at least one of an electrical signal delivery path and an acoustic signal delivery path, to provide for delivery of the electrical stimulation to the cochlea at a desired time relative to a time of arrival of acoustic stimuli at the cochlea, wherein the acoustic stimuli arriving at the cochlea and the electrical stimulation delivered to the cochlea at the desired time substantially simultaneously stimulate the cochlea.

Abstract: An embodiment of the present invention takes masking effects into consideration when determining stimulation signals for neural stimulation. These masking effects may be modeled using user-specific models determined by taking measurements for an implant system of an implant recipient. Or, the model may correspond to a group of individuals sharing a common characteristic or the population as a whole. These models may be, for example, psycho-physical models.

Abstract: A cochlear implant implementing a directional sound processing system is provided. Specifically, the cochlear implants implementing the present invention comprise a plurality of audio sensors arranged in at least one external component of the cochlear implant to spatially receive ambient sound. At least one audio sensor is located in one of the external components of the cochlear implant, while one other audio sensor is located elsewhere, such as in a component other than the first component. The cochlear implant includes an directional sound processor comprising an array processor and a sound processor to convert the received sounds into a cochlea stimulation instruction signal.

Abstract: An elongate electrode carrier member for implantation in a location external to the cochlear canals to position at least one, and likely many, electrodes sufficiently proximate to the organ of Corti to effectively deliver stimulation signals to the auditory nerve fibers of the cochlear. Generally, the carrier member is dimensioned to be implanted in a crevice, channel or pocket formed between the spiral ligament and bony capsule of the cochlear. Embodiments of the carrier member preferably have a minimized volume to accommodate insertion into such a crevice. In addition, embodiments of the carrier member comprise an elongate bulbous central region having electrodes disposed on the medial surface thereof, and elongate tapered side regions laterally extending from the central region. The side regions have rounded edges and are preferably flexible, while the carrier is configured to coil or turn toward the medial surface.
