Abstract: A patient-specific method of conditioning a cochlear electrode array so as to reduce insertion forces is provided. The method includes obtaining a 3D phantom of at least a portion of a scala tympani of a patient. The cochlear electrode array is inserted into and removed out of the 3D model of the scala tympani one or more times, to condition (e.g. soften) the electrode prior to insertion into the patient's scala tympani. Trauma when inserting the electrode into the cochlea is thus reduced.

Abstract: A system and method for inserting a cochlear implant electrode into a cochlea. A first magnet is fastened to a cochlear implant electrode. A second magnet is coupled, via magnetic attraction, to the first. A force is placed on the second magnet to push the first magnet, and thus also the cochlear implant electrode, into the cochlea. If a threshold force is exceeded, the first magnet and second magnet will separate, preventing a force on the second magnet from causing insertion of the cochlear implant electrode into the cochlea.

Abstract: A method of developing a weighting matrix for a cochlear implant patient is described. An electrode stimulus signal is derived from a first musical signal. A set of further stimulus signals is derived that have a defined musical relation to the first musical signal. A set of weighting values are selected for the stimulation electrodes for the electrode stimulus signal. Then the weighting values are set for the stimulation electrodes for each of the further stimulus signals. Each of the stimulus signals is consecutively presented to the patient and the weighting values individually adjusted for each of the further stimulus signals until the series of stimulus signals elicits an increasing pitch percept according to the defined musical relation. The adjusted weighting values are stored and assigned to a corresponding analysis channel.
