Components of the Investigational BrainGate Neural Interface System
CORTEX
(A) The recording sensor is a “Utah” microelectrode array (NeuroPort, prior manufacturer: Cyberkinetics Neurotechnology Systems; present manufacturer, Blackrock Neurotech; both, Salt Lake City, UT) consisting of 96 electrodes arranged on a 4 × 4-mm platform. During surgical placement, the microelectrode array is placed onto the cortical surface of the predetermined brain region of interest and a pneumatic inserter wand is used to apply a precise amount of force to the array, inserting the microelectrodes through the pial surface and into the upper layers of cortex. (B) The microelectrode array is connected through a bundle of gold wires to a percutaneous pedestal, which is affixed to the outer table of the cranium by titanium surgical screws. When not in use, the percutaneous pedestal is covered by a disposable fitted cap. (C) Signals from the pedestal are transmitted either wirelesslyClinical Trial Inclusion and Exclusion Criteria (as of December 31, 2021)Enrollment by Clinical Site
