Clinical Trials

An early feasibility study of the safety of an endovascular Motor Neuroprosthesis (MNP) in participants with severe upper limb dysfunction

Type of Study/Intervention


Recruitment Status

Not recruiting

Form of MS

Relapsing remitting MS, Relapsing MS, Secondary progressive MS, Primary progressive MS, Clinically isolated syndrome, People without MS

Brief summary

The Synchron Motor Neuroprosthesis (MNP) is intended to be used in subjects with severe upper limb 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.
