A multiple electrode cochlear implant [PDF]

The Journal of Laryngology & Otology, 1977
The University of Melbourne Departments of Otolaryngology and Electrical Engineering (UMDOLEE) receiving and stimulating component of a multiple-electrode cochlear implant hearing prosthesis produces constant stimulation. It has a stimulating pulse shape that minimizes the production of toxic substances and loss of metal from the electrodes, and this ...

Electrochemical properties of titanium nitride nerve stimulation electrodes: An in vitro and in vivo study

Frontiers in Neuroscience, 2015
The in vivo electrochemical behavior of titanium nitride (TiN) nerve stimulation electrodes was compared to their in vitro behavior for a period of 90 days. Ten electrodes were implanted in two Göttingen minipigs.

Structural changes in the retina after implantation of subretinal three-dimensional implants in mini pigs

Frontiers in Neuroscience, 2022
The retinal structural changes after subretinal implantation of three-dimensional (3D) microelectrodes were investigated in a mini pig. Three types of electrode were implanted into the subretinal spaces of nine mini pigs: 75-μm-high 3D electrodes on a ...

A challenging case of transvenous lead extraction

Türk Kardiyoloji Derneği Arşivi, 2015
A 72-year-old male patient with a 7-year history of cardioverter-defibrillator (ICD) implantation was admitted to our clinic with pocket infection. One year prior to this admission, he had undergone an unsuccessful extraction procedure at another clinic,

Grip control and motor coordination with implanted and surface electrodes while grasping with an osseointegrated prosthetic hand

Journal of NeuroEngineering and Rehabilitation, 2019
Background Replacement of a lost limb by an artificial substitute is not yet ideal. Resolution and coordination of motor control approximating that of a biological limb could dramatically improve the functionality of prosthetic devices, and thus reduce ...

Accuracy and Workflow Improvements for Responsive Neurostimulation Hippocampal Depth Electrode Placement Using Robotic Stereotaxy

Frontiers in Neurology, 2020
Background: Robotic stereotaxy is increasingly common in epilepsy surgery for the implantation of stereo-electroencephalography (sEEG) electrodes for intracranial seizure monitoring. The use of robots is also gaining popularity for permanent stereotactic
