Brief Summary:
The purpose of this study is to evaluate the tolerability and safety of the NeuroSigma eTNS system.

Condition or disease Intervention/treatment Phase
Seizure Disorder Device: External Trigeminal Nerve Stimulation (eTNS) Not Applicable

Detailed Description:

This study evaluates the safety and tolerability of the NeuroSigma eTNS system for the treatment of drug resistent partial seizures.

Up to 20 subjects, ages 18 - 75, with partial epilepsy will be enrolled in an acute 4-week tolerability study at Olive View/UCLA Medical Center .......

Enrolled subjects will be asked to maintain an accurate seizure calendar, and will be seen at the initial visit, then at two and four weeks.......
