Primary Outcome Measures:
  • The primary endpoint of this Study is to determine the safety of the BrainGate2 Neural Interface System. [ Time Frame: One year post-implant evaluation period ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • To investigate the feasibility of BrainGate2 and to establish the parameters for a larger clinical study, such as appropriate neural decoding algorithms, sample size, indices of measurement, success criteria, and endpoints. [ Time Frame: Course of the study ] [ Designated as safety issue: No ]

Estimated Enrollment: 15
Study Start Date: May 2009
Estimated Study Completion Date: December 2018
Estimated Primary Completion Date: September 2018 (Final data collection date for primary outcome measure)
Intervention Details:
    Device: Placement of the BrainGate2 sensor into the motor cortex
    The 4x4 mm BrainGate2 sensor is placed into the motor 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.
