• Study Type: interventional
• Target: 3
• Locations: 1 country
• Sites: 2

Brief Summary

The purpose of this study is to obtain preliminary device safety information and demonstrate proof of principle (feasibility) of the ability of people with tetraplegia to control a computer cursor and other assistive devices with their thoughts.

Conditions

Anarthria; Dysarthria; Tetraplegia; Spinal Cord Injuries; Amyotrophic Lateral Sclerosis; Brain Stem Infarctions; Locked in Syndrome; Muscular Dystrophies

Outcome Measures

Primary Outcomes (1)

• Device Safety

  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

Secondary Outcomes (1)

• Device Feasibility

  At participant exit from study, or up to 5 years

Study Arms (1)

BrainGate Neural Interface System

OTHER

Placement of the BrainGate2 sensor(s) into the speech-related cortex

Device: BrainGate Neural Interface System

Interventions

BrainGate Neural Interface System DEVICE

Placement of the BrainGate2 sensor(s) into the speech-related cortex

BrainGate Neural Interface System

Eligibility Criteria

• Age: 18 Years - 80 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Between 18 and 80 years of age.
• Participants must have a diagnosis of amyotrophic lateral sclerosis (ALS) as verified by a clinical expert in neurologic diseases.
• Participants with a diagnosis of ALS with anarthria, or severe dysarthria with decline in the preceding four months.
• Must be within a three-hour drive of the Study site and geographically stable for at least 15 months after enrollment.

You may not qualify if:

• Visual impairment such that extended viewing of a computer monitor would be difficult even with ordinary corrective lenses
• Chronic oral or intravenous steroids or immunosuppressive therapy
• Other serious disease or disorder that could seriously affect ability to participate in the study
