    Safety studies and preliminary patient trails with a new perimodiolar electrode array
    Clark, Graeme M. ; COWAN, ROBERT ; Saunders, Elaine ; TYKOCINSKI, MICHAEL ; COHEN, LAWRENCE ; Treaba, Claudiu ; BRIGGS, ROBERT ; Dahm, Markus ( 2000)
    A new perimodiolar electrode array, the curly-with stylet (CwS), has been developed and undergone safety trials in human cadaver temporal bones. The array was developed as a result of animal and modelling studies which indicated that there are potential advantages in situating the electrode array in closer proximity to the neural elements. Preliminary studies with four patients in Melbourne implanted with a developmental pre-curved array had supported the predictions of lower current requirements and possibly more focussed spread of excitation.

    Insertion study using new peri-modiolar electrode array designs [Abstract]

    Intracochlear multi-channel cochlear implants have been shown to successfully provide auditory information for profoundly deaf patients by electrically stimulating discrete populations of auditory nerve fibers via a scala tympani (ST) electrode array. Histological and radiological examination of implanted human temporal bones showed that the current straight Nucleus® array is usually positioned against the outer wall of the ST. An electrode array close to the modiolus could be expected to reduce stimulation thresholds and result in a more localized neural excitation pattern.
