Stimulation Management for a Multichannel Vestibular Neural Prosthesis

Proceedings of 2010 IEEE International Symposium on Circuits and Systems, 2010
This paper describes the stimulation management unit for a multichannel vestibular neural prosthesis. The unit is designed as part of a stimulator ASIC in the implantable subsystem of the prosthesis. This digital unit provides the stimulator ASIC the ability to generate biphasic current pulses at specified amplitude, duration and pulse rate to drive ...

[Recent progress in vestibular prosthesis].

Lin chuang er bi yan hou tou jing wai ke za zhi = Journal of clinical otorhinolaryngology head and neck surgery, 2023
Bilateral vestibulopathy（BVP） is one of the common diseases in the vestibular nervous system, with an incidence rate of about 4%-7% in the population, which can lead to a variety of body dysfunctions. At present, there are two main treatment methods for BVP. One is vestibular rehabilitation.

Tilt Determination in MEMS Inertial Vestibular Prosthesis

Journal of Biomechanical Engineering, 2006
Background: There is a clear need for a prosthesis that improves postural stability in the balance impaired. Such a device would be used as a temporary aid during recovery from ablative inner-ear surgery, a postural monitor during rehabilitation (for example, hip surgery), and as a permanent prosthesis for those elderly prone to falls.

Development of a biophysical model for vestibular prosthesis research

Journal of Vestibular Research, 2003
Physiologic properties of primary vestibular neurons are compared and contrasted with properties of primary auditory neurons. The differences and similarities suggest possible coding strategies for a vestibular implant. The degree of spike rate variability, or coefficient of variation (CV), is a prominent physiological property of vestibular neurons ...

Vestibular prosthesis design for restoring balance

Analog Integrated Circuits and Signal Processing, 2013
Over the last decade significant progress has been made in developing neuroprosthetic devices to restore balance. However, there still remain major challenges to overcome before an advanced clinical implant is created. These include efficient wireless power and data transmission, multichannel stimulation with minimal crosstalk, effective and safe ...

Optical nerve stimulation for a vestibular prosthesis

SPIE Proceedings, 2009
Infrared Nerve Stimulation (INS) offers several advantages over electrical stimulation, including more precise spatial selectivity and improved surgical access. In this study, INS and electrical stimulation were compared in their ability to activate the vestibular branch of the VIII th nerve, as a potential way to treat balance disorders.

An integrated vestibular-cochlear prosthesis for restoring balance and hearing

2011 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2011
An integrated vestibular-cochlear implant can be rapidly prototyped and clinically tested by modifying an existing modern cochlear implant. The modifications include addition of gyroscope sensors and reallocation of several electrodes that are normally used for auditory nerve stimulation to the semicircular canals, while sharing the external DSP ...

An Implantable Closed-Loop Vestibular Prosthesis

2013
This paper presents an implantable closed-loop vestibular prosthesis for restoring three-dimensional (3-D) balance sensation. The prosthesis consists of an external part and an implantable part. The external part collects the head motion and controls the stimulation from the implantable part accordingly.

A fully-integrated semicircular canal processor for an implantable vestibular prosthesis

2008 15th IEEE International Conference on Electronics, Circuits and Systems, 2008
This paper presents a fully-integrated semicircular canal processor for an implantable vestibular prosthesis. The system includes the entire processing chain required from the microsensor interface, through the required biomimetic transfer characteristics, to a current-mode signal, suitable for feeding the stimulator.

Acclimation to Chronic Constant-Rate Peripheral Stimulation Provided by a Vestibular Prosthesis

IEEE Transactions on Biomedical Engineering, 2006
We are developing two types of vestibular prosthetics that electrically stimulate afferent neurons. One type replaces absent sensory function by providing stimulation that modulates above and below a baseline established with the head stationary. The other type provides constant stimulation and is turned on only when necessary, for example, to override
