The purpose of this clinical study is to allow the investigation of the Neural Bridging System for participants with tetraplegia to assess if the investigational device can reanimate a paralyzed limb under voluntary control by the participant's thoughts.
This study plans to enroll participants who have been diagnosed with C4- C6 ASIA A spinal cord injuries (motor and sensory complete neurologic injuries), who are more than 1 year post injury, and who are neurologically stable.
