ICVP - A Phase I Clinical Trial to Determine the Feasibility of a Human Cortical Visual Prosthesis for People With Blindness
Illinois Institute of Technology
Summary
The purpose of this study is to determine the feasibility of producing artificial vision in persons with blindness. Study participants will have wireless electrical stimulators implanted into the cortical vision processing areas of their brains. The ability of the participants to perceive artificial vision in response to electrical stimulation will be assessed.
Description
The objective of this study is to test the safety of the ICVP system and the feasibility of eliciting visual percepts in response to electrical stimulation in persons with blindness. The electrical stimulation is provided by wireless floating microelectrode arrays (WFMAs) that are part of the ICVP system. The WFMAs are implanted in the visual cortex. Five participants will take part in the study and each participant will have multiple WFMA devices implanted in their visual cortex on one side of the brain. After recovery from surgery, participants will begin a series of tests to assess the abil…
