Experience with implanted electrodes

Neurosurgery, 1977
Implant units, manufactured by Medtronic, Inc., have been implanted in 31 patients for treatment of drop-foot. The principal problem encountered in this series was inflammatory reaction. This was observed in seven patients, and was serious enough in five to require removal of the implant.

Intracerebral electrode implantation system

Journal of Neurosurgery, 1983
✓ A new technique for deep-brain electrode implantation is described. A very flexible nontraumatic electrode guided by a central stylet and a new electrode head-fixation screw are the two unique features of this system. Electrodes can be guided precisely and their watertight fixation to the bone by means of the special screw is reliable and totally ...

Chronically implanted intrafascicular recording electrodes

Annals of Biomedical Engineering, 1991
A newly designed intrafascicular electrode for chronic neural recording was studied by implanting 12 electrodes in the radial nerves of 6 cats for 6 months. Action potentials were monitored at specified intervals throughout the experiment. The number and size of the signals recorded suggest that this type of electrode provides information that is ...

Electrode Migration in Patients with Perimodiolar Cochlear Implant Electrodes

Audiology and Neurotology, 2015
Migration of a cochlear implant electrode is a hitherto uncommon complication. So far, array migration has only been observed in lateral wall electrodes. Between 1999 and 2014, a total of 27 patients received bilateral perimodiolar electrode arrays at our institution.

Intracochlear Position of Cochlear Implant Electrodes

Acta Oto-Laryngologica, 1999
There are many different types of cochlear implants available on the market today and they are constantly being re-evaluated and changed. Knowledge of the exact position of the electrode within the cochlea is important in order to improve the electrical stimulation of the hearing nerve by the implants.

Management of Cochlear Implant Electrode Migration

Otology & Neurotology, 2016
The present study reviewed a cochlear implant (CI) patient population after surgery, which received a free-fitting electrode carrier designed for hearing preservation. The aim was to determine the rate of electrode migration of the CI electrodes and present clinical and surgical implications.Retrospective patient review.Tertiary referral university ...

Trauma After Electrode Implantation

Archives of Neurology, 1976
To the Editor.— Robinson et al ( Arch Neurol 32:98, 1975) have made a unique methodological contribution toward understanding the effects of chronic electrode implantation on surrounding tissue. It would be unwise, however, to generalize their results to other animals (including man) or to accept, without further considerations, their conclusion about

Perimodiolar Electrodes in Cochlear Implant Surgery

Acta Oto-Laryngologica, 2001
Perimodiolar-positioned cochlear implant electrodes have been developed in order to bring the electrode contacts as close as possible to the spiral ganglion cells, which are the target of electrostimulation. This results in lower electrical thresholds, higher dynamic ranges and less channel interaction when compared with normal implant electrodes which
