Flexible electrode assembly having variable pitch electrodes for a stimulating medical device

Abstract: An electrode assembly for use in a prosthetic hearing implant, the electrode assembly comprising: an elongate carrier member for implantation into the cochlea, the carrier member having a proximal end adapted to be positioned in a basal region of the cochlea, and a distal end adapted to be positioned in an apical region of the cochlea; and a plurality of electrodes disposed along a longitudinal surface of the carrier member, wherein the plurality of electrodes have a predetermined spacing to attain a desired flexibility along the length of the carrier member.

Speech perception outcome measures in prelingually deaf children up to four years after cochlear implantation.

Abstract: The aim of our study is to evaluate the auditory performance of congenitally deaf children having cochlear implants, with a range of speech perception tests administered during a 4-year follow-up period. In common with other groups," we are particularly interested in how the age at implantation affects outcome. One of the difficulties with this task is that in addition to the time of implantation, several factors influence performance, such as age at onset of deafness, residual hearing, educational setting, family support, and communication mode.· Ideally, one would need to study a homogeneous population in which all of these factors are equal; this is, of course, impossible. However, our own group of patients is probably more homogeneous than most others. In part, this is because Canadian health care resources for cochlear implantation have been limited, and therefore, our eligibility criteria for implantation have been relatively strict. Stringent audiometric inclusion-exclusion parameters were adhered to. We have only performed implantation in children with nonossified and patent cochleas allowing full electrode array insertion. All patients' families were committed to oralism as the main communication mode for their children. We have also had a rigid policy of not implanting children unless auditory-verbal therapy was planned in either educational or health care environments. Our own program is heavily weighted toward providing auditory-verbal therapy, either within the program or in liaison with programs in the community. Our data are based only on speech perception tasks that were evaluated in our own institution under consistent testing conditions.

From nucleus 24 to 513: changing cochlear implant design affects auditory response thresholds.

Abstract: ObjectivesWe asked how thresholds of auditory activity evoked by a recent research cochlear implant, the Nucleus 513, compared with those evoked by previous generations of devices from the same manufacturer.Study DesignProspective repeated measures.SettingTertiary pediatric hospital.PatientsA total

Telephone use and the factors influencing it among cochlear implant patients

Abstract: ObjectiveTo investigate telephone use in cochlear implant patients and to determine factors most likely to influence telephone use.MethodsSurveys were mailed to 504 cochlear implant patients treated at Sunnybrook Health Sciences Hospital.ResultsTwo hundred four patients returned surveys (49%), 87% were classified as telephone users. No differences were found in age, pre-implant hearing characteristics, and the majority of post-implant behaviors. Education and post-implant sound perception scores were found to be significantly different (P < 0.05) between telephone users and non-users.DiscussionTelephone use among cochlear implant patients shows a positive increase compared to previous studies. In addition, we find that higher attained education and post-implant hearing scores to be independently correlated to telephone use.

Music Training for Children With Sensorineural Hearing Loss Improves Speech-in-Noise Perception

Abstract: Purpose A growing body of evidence suggests that long-term music training provides benefits to auditory abilities for typical-hearing adults and children. The purpose of this study was to evaluate how music training may provide perceptual benefits (such as speech-in-noise, spectral resolution, and prosody) for children with hearing loss. Method Fourteen children aged 6-9 years with prelingual sensorineural hearing loss using bilateral cochlear implants, bilateral hearing aids, or bimodal configuration participated in a 12-week music training program, with nine participants completing the full testing requirements of the music training. Activities included weekly group-based music therapy and take-home music apps three times a week. The design was a pseudorandomized, longitudinal study (half the cohort was wait-listed, initially serving as a passive control group prior to music training). The test battery consisted of tasks related to music perception, music appreciation, and speech perception. As a comparison, 16 age-matched children with typical hearing also completed this test battery, but without participation in the music training. Results There were no changes for any outcomes for the passive control group. After music training, perception of speech-in-noise, question/statement prosody, musical timbre, and spectral resolution improved significantly, as did measures of music appreciation. There were no benefits for emotional prosody or pitch perception. Conclusion The findings suggest even a modest amount of music training has benefits for music and speech outcomes. These preliminary results provide further evidence that music training is a suitable complementary means of habilitation to improve the outcomes for children with hearing loss.
