Official Title ^ICMJE

BrainGate2: Feasibility Study of an Intracortical Neural Interface System for Persons With Tetraplegia

Brief Summary

The purpose of this study is to obtain preliminary device safety information and demonstrate proof of principle (feasibility of efficacy) of the ability of people with tetraplegia to control a computer cursor and other assistive devices with their thoughts.

Detailed Description

The goal of the BrainGate2 research and development project is to identify the core methods and features for a medical device that could allow people with paralysis to recover a host of abilities that normally rely on the hands.
