EXCLUSION CRITERIA

The subject must not meet any of the following exclusion criteria:

1. Has contraindications for DBS surgery, including any intracranial abnormality (e.g., generalized atrophy, vascular malformation, hydrocephalus, hematoma, cavernous or venous angioma, tumor or metastases, midline shift, etc.) or metallic implant (e.g., aneurysm clip, cochlear implant, etc.) or other clinically significant space-occupying lesion which in the opinion of the surgeon would impact the ability to target and place the leads or IPG

5. Any medical condition, such as cognitive impairment, dementia, seizures, congestive heart failure, unstable angina, uncontrolled diabetes, renal failure requiring dialysis, or any other severe medical condition that could interfere with study procedures, confound the assessment of study endpoints, prevent proper data collection, or that, in the opinion of the investigator, would compromise the subject's ability to participate

6. Confirmation of diagnosis of a terminal illness associated with survival <12 months

7. Needs repeated MRI scans

8. Requires diathermy, transcranial magnetic stimulation (TMS), or electroconvulsive therapy (ECT)

9. Has an electrical or electromagnetic implant (e.g., cochlear prosthesis, pacemaker, neurostimulator, etc.) or plans to obtain, an active implanted medical device (AIMD) and/or an implanted medication pump (e.g., DUOPA™ infusion pump) and/or is treated with a portable infusion pump for any indication

10. Is on anticoagulant therapy which cannot be paused for >5 days before surgery

11. A history of cranial surgery including ablation procedure or any other previous neurosurgical procedure for the treatment of PD symptoms on either side of the brain

12. Is currently participating in another clinical study (excluding any sub-study of the present trial). The sponsor will not grant waivers or protocol exceptions to any inclusion or exclusion criteria. Safety of subjects is the utmost concern and will be prioritized at every stage throughout this protocol.
