Feasibility of the BrainGate2 Neural Interface System in Persons With Tetraplegia (BG-Tablet-01) (BG-Tablet-01)

November 26, 2025 updated by: Leigh R. Hochberg, MD, PhD.

Intuitive, Complete Neural Control of Tablet Computers for Communication

People with brainstem stroke, advanced amyotrophic lateral sclerosis (ALS, also known as Lou Gehrig's disease), or other disorders can become unable to move or speak despite being awake and alert. In this project, the investigators seek to further translate knowledge about interpreting brain signals related to movement, and to further develop an intracortical brain-computer interface (iBCI) that could restore rapid and intuitive use of communication apps on tablet computers by people with paralysis.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Sensor implant duration for at least one-year without any device-related Serious Adverse Events or explant
Time Frame: 1 year

To determine the safety of the Sensor and overall safety of the System. Participants will be considered a success for this safety measure if they are successfully implanted with the Sensor(s) and:

  1. the sensors are not explanted for safety reasons during the one-year post-implant evaluation period.
  2. there are no device-related Serious Adverse Events that result in death or permanently increased disability during the one-year post-implant evaluation period.
1 year
