  • Patent number: 11006846
    Abstract: A method is provided for processing a neural measurement obtained in the presence of noise, in order to detect whether a locally evoked neural response is present in the neural measurement. A first neural measurement is obtained from a first sense electrode. A second neural measurement is contemporaneously obtained from a second sense electrode spaced apart from the first electrode along a neural pathway of the neural response. A neural response decay is determined, being a measure of the decay in the neural response from the first sense electrode to the second sense electrode. A ratio of the neural response decay to an amplitude normalising term is calculated. From the ratio it is determined whether a locally evoked neural response is present in the neural measurement.

  • Patent number: 11012796
    Abstract: An external portion of an auditory prosthesis includes an external magnet that interacts with an implanted magnet to hold the external portion against the skin of a recipient. A magnetic component can be disposed proximate either or both of the external magnet or implanted magnet to channel the magnetic field associated therewith. The magnetic component can be moved relative to its associated magnet so as to adjust the magnetic field, and thus, the retention force between the magnets.

  • Patent number: 11007362
    Abstract: An exemplary method of inserting a peri-straight electrode array into a cochlea of a recipient includes positioning the peri-straight electrode array and an insertion tool within the recipient such that a distal end of the insertion tool is provided within the recipient at a location that is outside and not touching the cochlea of the recipient, and a straight distal portion of the peri-straight electrode array extends away from the distal end of the insertion tool and into the cochlea. The exemplary method further includes manually interacting with the insertion tool to advance the straight distal portion and at least some of a pre-curved proximal portion into the cochlea without allowing the insertion tool to enter or come in contact with the cochlea, and removing the insertion tool from the recipient such that the peri-straight electrode array remains within the cochlea after the insertion tool is removed from the recipient.
