An electronic prosthesis mimicking the dynamic vestibular function.
This paper presents a functional architecture, system level design, and electronic evaluation of a unilateral vestibular prosthesis. The sensing unit of the prosthesis is a custom-designed one-axis micro-electromechanical system (MEMS) gyroscope. Similar to the natural semicircular canal, the MEMS gyroscope senses angular motion of the head and generates voltages proportional to the correspondi...
متن کاملIntracanalicular meningioma mimicking vestibular schwannoma.
SUMMARY Three cases of intracanalicular meningioma mimicking vestibular schwannoma are presented. In each case, a contrast-enhancing mass filling the internal auditory canal was identified on MR images and was originally diagnosed as a vestibular schwannoma. Although it is difficult to differentiate definitively between these lesions preoperatively, imaging findings inconsistent with a diagnosi...
متن کاملTilt determination in MEMS inertial vestibular prosthesis.
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. METHOD OF APPROACH Recently developed, small instruments h...
متن کاملEye movement studies with a vestibular prosthesis
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. This vestibular prosthesis provides pulsatile electrical stimulation to the vestibular nerve. Prosthesis effectiveness is assessed ...
متن کاملTowards a Wireless Implantable Vestibular Prosthesis
This paper presents the preliminary design of the integrated stimulator and telemetry subsystems for a vestibular prosthesis to restore balance function. The work is part of the European project CLONS. The stimulator is designed to provide biphasic current pulses at specified amplitude, duration and rate to stimulate the semicircular canals in the vestibular system. Power and data transfer is p...
