摘要： In electrically stimulating neural tissue it is important to prevent over stimulation and unbalanced stimulation which would cause damage to the neural tissue, the electrode, or both. It is critical that neural tissue in not subjected to any direct current or alternating current above a safe threshold. Further, it is important to identify defective electrodes as continued use may result in neural and further electrode damage. Systems and stimulator control mechanisms to prevent damage to neural tissue.

摘要： The present invention is wireless visual prosthesis with a remote driver for the external coils this, among other things, provides for a magnetic resonance image (MRI) safe visual prosthesis. fMRI is an effective tool for analyzing cortical responses to neural stimulation, such as from a visual prosthesis. However, the external electronics of a visual prosthesis cannot operate in a MRI field. The present invention provides a radio frequency shielded link between a video processing unit, driver circuitry and the coils used for communicating with the implantable portion of the visual prosthesis.
