Study Start Date: May 2009
Estimated Study Completion Date: December 2021
Estimated Primary Completion Date: September 2021 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
BrainGate
BrainGate Neural Interface System
Device: Placement of the BrainGate2 sensor(s) into the motor-related cortex
One or two 4x4 mm BrainGate2 sensor(s) are placed into the motor-related cortex, connected to a percutaneous pedestal. Neural recordings are made at least weekly for a year or more.
Other Names:
  • BrainGate
  • NeuroPort
  • neural prosthesis
  • neural prosthetic
  • neuroprosthetic
  • brain computer interface
  • brain-computer interface

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.
