Official Title: Stereotactic Laser Ablation for Temporal Lobe Epilepsy

Brief Summary: The study is designed to evaluate the safety and efficacy of the Visualase MRI-guided laser ablation system for mesial temporal epilepsy (MTLE).

Detailed Summary:

The purpose of the study is to evaluate the safety and efficacy of the Visualase MRI-guided laser ablation system for necrotization or coagulation of epileptogenic foci in patients with intractable mesial temporal lobe epilepsy.

The study will include approximately 120 adult patients with drug-resistant MTLE treated at selected epilepsy centers across the United States. After the Visualase procedure, patients will be followed for 12 months and evaluated for freedom from seizures, quality of life, adverse events, and neuropsychological outcomes.
