• A Pilot Study to Evaluate MR-guided Laser Ablation of Focal Lesions in Patients with Medically Refractory Partial Epilepsy Rochester, Minn., Jacksonville, Fla.

  To investigate whether MR-guided laser induced thermal therapy in patients diagnosed with focal lesional epilepsy using the Visualase Thermal Therapy System is both a feasible and safe minimally invasive technique for control of seizures in such patients.

• Device to Increase Accuracy and Efficiency of Image-guided sEEG Procedures Rochester, Minn.

  The purpose of this study is to evaluate the custom made Stealth Arc Delivery device versus a commercially available device to improve the precision, efficiency and workflow of implanting Stereo electroencephalography (sEEG) electrodes into patients who have medically unmanageable epilepsy. Successful sEEG monitoring can identify areas of the brain where epileptic seizures originate for later surgical removal.
