Experimental: WFMA Cortical Visual Prosthesis Single-arm Study
The WFMA is an electronic device that is implanted in the cortical vision processing regions of the brain to produce artificial vision.
Device: WFMA - wireless floating microelectrode array
Wirelessly transmitted patterns of electrical stimulation will be delivered to the visual cortex of study participants to generate visual percepts.
- To test the safety of the WFMA-based cortical interface. [ Time Frame: From two-weeks post-op to end of device use, up to 3 years. ]Safety is defined as the number of adverse events occurring over the study period due to surgical complications or use of the WFMA device.
- To test the efficacy of the WFMA-based cortical interface [ Time Frame: From four-weeks post-op to end of device use, up to 3 years. ]Efficacy is defined as establishing a chronic intracortical interface for which the ability to elicit visual percepts in response to electrical stimulation can be demonstrated with stimulus intensities of 16 nanocoulombs per phase or less.
