Brief summary

The Synchron Motor Neuroprosthesis (MNP) is intended to be used in subjects with severe motor impairment, unresponsive to medical or rehabilitative therapy and a persistent functioning motor cortex. The purpose of this research is to evaluate safety and feasibility. The MNP is a type of implantable brain computer interface which bypasses dysfunctional motor neurons. The device is designed to restore the transmission of neural signal from the cerebral cortex utilized for neuromuscular control of digital devices, resulting in a successful execution of non-mechanical digital commands.
