This paper presents an innovative neurostimulator for use with a suprachoroidal retinal prosthesis. Clinical test results are described which show it to be effective in eliciting visual percepts in a profoundly vision-impaired subject with approximately 20 years of light perception vision only. The final device is a highly configurable neurostimulator in a relatively small form factor, with potential applications in a number of emerging clinical neurostimulation applications, including epileptic seizure suppression and closed-loop deep brain stimulation.
