A Microcoil-Based Cortical Visual Prosthesis

Abstract

We are developing a cortical visual prosthesis that can restore vision to the blind. Our approach is based on the recent development of micro-coils, small implantable inductors that magnetically activate neurons. Much proof-of concept testing has shown that coils are more selective and maintain consistency longer than conventional microelectrodes. The Aims here focus on the design and development of a device that can be safely implanted into humans, the initial testing of the new prototypes, and then establishing safety and efficacy of the implants. Here, we describe our ongoing progress with the design of the device, a wide range of safety and performance testing as well as progress towards psychophysical testing in non-human primates.
