The eventual goal will be a pivotal trial for a de novo 510k for dEEG-guided rTMS for suppressing epileptic seizures. The more limited goal of suppressing epileptic discharges (spikes) will allow careful evaluation of safety while demonstrating feasibility of the therapeutic action. In preparing this request, the investigators have studied the guidance on the special controls described for rTMS in the FDA Class II Special Controls Guidance Document: Repetitive Transcranial Magnetic Stimulation (rTMS) Systems, Document issued on: July 26, 2011. In addition, because patients with epilepsy are at particular risk of seizures that may be induced or exacerbated by rTMS, investigators also address the unique risks of this population, the existing evidence on safety and efficacy of rTMS treatment of the epileptic focus, and the mitigation the investigators propose to minimize the risks.
