A Micro-Coil Based Cortical Visual Prosthesis

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 micro-electrodes. The Aims here are 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. At the completion of the first year, we describe here our progress with the design and testing of the device as well as our plans to begin the safety testing as well as the efficacy testing in non-human primates.
