Ethical issues in the development of a vestibular prosthesis

2011 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2011
During the development of a neural prosthesis, various ethical aspects have to be considered. These range from the basic design of the prosthesis and manufacturing of the various components and the system using biocompatible materials to extensive in vitro and in vivo testing and investigations in the animal model, before taking the final step and ...

Towards an Implantable Vestibular Prosthesis: The Surgical Challenges [PDF]

2007 3rd International IEEE/EMBS Conference on Neural Engineering, 2007
Restoring the sensation of inertia in individuals with balance-related impairments is achievable through development of an artificial vestibular prosthesis, based on the cochlear implant paradigm. The vestibular system, however, involves added complexity in surgical methods required for reliable implantation, thus limiting widespread feasibility.

Alignment of angular velocity sensors for a vestibular prosthesis [PDF]

Journal of NeuroEngineering and Rehabilitation, 2012
Vestibular prosthetics transmit angular velocities to the nervous system via electrical stimulation. Head-fixed gyroscopes measure angular motion, but the gyroscope coordinate system will not be coincident with the sensory organs the prosthetic replaces.

A Vestibular Prosthesis With Highly-Isolated Parallel Multichannel Stimulation [PDF]

IEEE Transactions on Biomedical Circuits and Systems, 2015
This paper presents an implantable vestibular stimulation system capable of providing high flexibility independent parallel stimulation to the semicircular canals in the inner ear for restoring three-dimensional sensation of head movements. To minimize channel interaction during parallel stimulation, the system is implemented with a power isolation ...

Development of a closed-loop neural prosthesis for vestibular disorders

Journal of Automatic Control, 2010
Vestibular disorders can cause severe problems including spatial disorientation, imbalance, nausea, visual blurring, and even cognitive deficits. The CLONS project is developing a closed-loop, sensory neural prosthesis to alleviate these symptoms [1]. In this article, we outline the different components necessary to develop this prosthetic.

Eye movement studies with a vestibular prosthesis. [PDF]

, 2010
Vestibular loss, which can manifest as dizziness, imbalance, or spatial disorientation, is widespread and often caused by inner ear hair cell malfunction. To address these problems, we are developing a vestibular implant analogous to cochlear implants for the deaf.

A closed-loop neural prosthesis for vestibular disorders

10th Symposium on Neural Network Applications in Electrical Engineering, 2010
Vestibular disorders can cause severe problems including nausea, inability to concentrate, and visual deficits. The CLONS project is developing a closed-loop sensory neural prosthesis to alleviate these symptoms. Conceptually, the prosthesis restores vestibular information by stimulating the semicircular canals according to measurements from inertial ...

Vestibular prosthesis tested in rhesus monkeys [PDF]

2011 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2011
We are studying the effectiveness of a semicircular canal prosthesis to improve postural control, perception of spatial orientation, and the VOR in rhesus monkeys with bilateral vestibular hypofunction. Balance is examined by measuring spontaneous sway of the body during quiet stance and postural responses evoked by head turns and rotation of the ...

The contribution of visual and vestibular information to spatial orientation by 6- to 14-month-old infants and adults [PDF]

, 2011
Although there is much research on infants' ability to orient in space, little is known regarding the information they use to do so. This research uses a rotating room to evaluate the relative contribution of visual and vestibular information to location

Longitudinal performance of an implantable vestibular prosthesis [PDF]

Hearing Research, 2015
Loss of vestibular function may be treatable with an implantable vestibular prosthesis that stimulates semicircular canal afferents with biphasic pulse trains. Several studies have demonstrated short-term activation of the vestibulo-ocular reflex (VOR) with electrical stimulation. Fewer long-term studies have been restricted to small numbers of animals
