Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
