A multiple-electrode array for a cochlear implant.
A satisfactory multiple-electrode array for a cochlear implant has been developed. This can be passed around the turns of the cochlea if it is first introduced into the scala tympani through an opening in the apical turn.
متن کاملA cochlear implant electrode.
This study has shown that an electrode array can be passed along the hold length of the cochlea if it is inserted through and opening in the scala tympani of the apical turn. The electrode must have the appropriate mechanical properties and some of these were stiffness and extensibility. The electrode and operative approach should be helpful in stimulating the terminal auditory nerve fibres on ...
متن کاملShape Optimization of Cochlear Implant Electrode Array using Genetic Algorithms
−Finite element analysis is used to compute the current distribution of the human cochlea during cochlear implant electrical stimulation. Genetic algorithms are then applied in conjunction with the finite element analysis to optimize the shape of cochlear implant electrode array based on the energy deposited in the spiral ganglion cells region. The goal is to improve the focus of electrical ene...
متن کاملAn overview of cochlear implant electrode array designs
Cochlear implant electrode arrays are designed with specific characteristics that allow for the preservation of intra-cochlear structures during the insertion process, as well as during explantation. Straight lateral wall (LW) electrode arrays and pre-curved modiolar hugging (MH) electrode arrays are the two types that are commercially available. Although there is a third type of electrode arra...
متن کاملIndividual Optimization of the Insertion of a Preformed Cochlear Implant Electrode Array
Purpose. The aim of this study was to show that individual adjustment of the curling behaviour of a preformed cochlear implant (CI) electrode array to the patient-specific shape of the cochlea can improve the insertion process in terms of reduced risk of insertion trauma. Methods. Geometry and curling behaviour of preformed, commercially available electrode arrays were modelled. Additionally, t...
