“…Significant progress has been made in efficient fitting of cochlear implants, includes measuring only the comfortable loudness level (Clarion), streamlining the mapping by interpolating the T and C levels in a subset of the electrodes [168], and optimizing the map by genetic algorithms [169]. Because structured training has been shown to benefit cochlear implant performance [170], a future fitting system may be integrated with a structured training system.…”

As the most successful neural prosthesis, cochlear implants have provided partial hearing to more than 120,000 persons worldwide; half of which being pediatric users who are able to develop nearly normal language. Biomedical engineers have played a central role in the design, integration and evaluation of the cochlear implant system, but the overall success is a result of collaborative work with physiologists, psychologists, physicians, educators, and entrepreneurs. This review presents broad yet in-depth academic and industrial perspectives on the underlying research and ongoing development of cochlear implants. The introduction accounts for major events and advances in cochlear implants, including dynamic interplays among engineers, scientists, physicians, and policy makers. The review takes a system approach to address critical issues from design and specifications to integration and evaluation. First, the cochlear implant system design and specifications are laid out. Second, the design goals, principles, and methods of the subsystem components are identified from the external speech processor and radio frequency transmission link to the internal receiver, stimulator and electrode arrays. Third, system integration and functional evaluation are presented with respect to safety, reliability, and challenges facing the present and future cochlear implant designers and users. Finally, issues beyond cochlear implants are discussed to address treatment options for the entire spectrum of hearing impairment as well as to use the cochlear implant as a model to design and evaluate other similar neural prostheses such as vestibular and retinal implants.

“…If any of these electrodes were deactivated in programming, the adjacent electrode was used. The interpolation of the electrodes is used in clinical practice and establishes the minimum and maximum levels from a sample of electrodes (19) . The other parameters of the programming that compose the map, such as speech coding strategy, speed, and number of maxima, were not modified during the RP and live programming (LP).…”

DescritoresThe RP is a simple and effective procedure for programming cochlear implant devices and, although there were differences in the stimulation levels of some electrodes, it did not interfere in the speech perception outcomes. RESUMOObjetivo: verificar a efetividade da programação remota do implante coclear por meio dos níveis de estimulação e resultados nos testes de percepção de fala e audiometria em campo livre. Métodos: Foram selecionados 12 pacientes de ambos os gêneros, com idade entre 18 e 59 anos, usuários de implante coclear do mesmo modelo de unidade interna e processador de fala por no mínimo 12 meses. As programações remota (PR) e presencial (PP) foram realizadas no mesmo dia, medindo-se os níveis mínimos (níveis T) e máximos (níveis C) de estimulação de cinco eletrodos, com interpolação dos demais. Foram aplicados testes de percepção de fala (frases em contexto aberto e monossílabos -gravação a 65 dBNPS) e audiometria em campo livre nas frequências de 250 a 8.000 Hz.Os resultados foram comparados entre PR e PP. Resultados: Houve diferença na média dos níveis T em três eletrodos e dos níveis C em um eletrodo. Não houve diferença entre os resultados obtidos nos testes de percepção de fala e nos limiares audiométricos na PP e PR. Conclusão: A realização da programação remota é simples e eficaz para a programação dos dispositivos de implante coclear e, embora tenha mostrado diferenças nos níveis de estimulação, não interferiu no desempenho da percepção de fala.

“…Plant et al 77 showed that 2 streamlined techniques could be successfully used in the clinical setting. The first technique was interpolation across 3 measured threshold levels and 3 measured comfortable listening levels, while the other was interpolation across 5 measured threshold or comfortable levels and the interpolated profile was used for fitting the alternative profile.…”

Cochlear Limited (Cochlear™) released the fourth-generation cochlear implant system, Nucleus® Freedom™, in 2005. Freedom is based on 25 years of experience in cochlear implant research and development and incorporates advances in medicine, implantable materials, electronic technology, and sound coding. This article presents the development of Cochlear's implant systems, with an overview of the first 3 generations, and details of the Freedom system: the CI24RE receiver-stimulator, the Contour Advance™ electrode, the modular Freedom processor, the available speech coding strategies, the input processing options of SmartSound™ to improve the signal before coding as electrical signals, and the programming software. Preliminary results from multicenter studies with the Freedom system are reported, demonstrating better levels of performance compared with the previous systems. The final section presents the most recent implant reliability data, with the early findings at 18 months showing improved reliability of the Freedom implant compared with the earlier Nucleus 3 System. Also reported are some of the findings of Cochlear's collaborative research programs to improve recipient outcomes. Included are studies showing the benefits from bilateral implants, electroacoustic stimulation using an ipsilateral and/or contralateral hearing aid, advanced speech coding, and streamlined speech processor programming.
