EXCLUSION CRITERIA:
1. Unrealistic expectations regarding the potential benefits of the device, in the opinion of the Investigator(s).
2. Active infection or unexplained fever in the 48 hours prior to informed consent.
3. Major psychiatric disorder that may adversely impact the participant's safety or study compliance (e.g., severe depression, psychotic features, personality disorder, severe emotional lability, substance abuse), in the opinion of the Investigator(s).
4. Dementia or cognitive dysfunction that would impact the participant's ability to participate in study activities, in the opinion of the Investigator(s).
5. Active implanted device (e.g., deep brain stimulator, cardiac defibrillator, pacemaker, vagal nerve stimulator, spinal cord stimulator, diaphragmatic pacer, etc.).
6. Known allergy to patient-contacting materials included in the implanted device (listed in Physician Implant Manual).
7. Contraindication to angiographic imaging or iodine contrast media.
8. History of central venous sinus thrombosis.
9. Recent history of new venous thromboembolic event (in the 6 months prior to implant) or recurrent history of venous thromboembolic disease.
10. Contraindication to antithrombotic therapy, in the opinion of the Investigator(s).
11. Participant is at substantially increased risk of infection, including immunocompromised status, recurrent or chronic infection, or poorly controlled diabetes mellitus.
12. Significant risk of non-healing of the subcutaneous pocket incision, including history of chronic non-healing surgical wounds or poorly controlled diabetes mellitus.
13. Currently receiving or expected to require medical treatment that may be precluded by device implant, including magnetic resonance imaging, transcranial magnetic stimulation, electroconvulsive therapy, transcranial ultrasound, shortwave, microwave, and/or therapeutic ultrasound diathermy, or balloon angioplasty or stenting in the target vessel.
14. Pregnant or breast feeding.
15. Patients who are currently enrolled in any other clinical trial that would confound interpretation of safety or effectiveness data or may interfere with the ability to meet study requirements.
16. Patients with ALS due to SOD1 mutations on gene therapy.
17. Any other disease or disorder that could significantly affect participation in the study, in the opinion of the Investigator(s). Examples may include corrected vision insufficient for viewing computer screens or hearing insufficient for following verbal instructions, which might impact the participant's ability to participate in BCI training and testing.
