A clinical study of a laser ablation procedure for drug-resistant epilepsy is currently enrolling eligible patients who would like to participate. Centers participating in the study will research whether laser ablation is a safe and effective treatment option for certain patients with uncontrolled seizures caused by mesial temporal lobe epilepsy (MTLE).
The SLATE study will use the Medtronic VisualaseTM MRI-guided laser ablation system.
The Visualase system is used to perform minimally invasive laser surgery on soft tissue in the body. For neurosurgery, a surgeon guides a thin laser fiber through a small hole into the brain. The laser heats up and destroys a defined area of abnormal brain tissue, minimizing risk of potential damage to surrounding healthy tissue.
The patient is in a magnetic resonance imaging (MRI) scanner throughout the process. This lets the surgeon see an image of the brain, the laser probe placement, and how much tissue is being heated up and destroyed during the procedure.
Visualase is currently considered an investigational device for treatment of drug-resistant MTLE. The FDA has cleared the use of Visualase in neurosurgery and other surgical specialties.

Medtronic will pay for the study device and any tests or procedures done just for the research study. However, you or your insurance company may be billed for any tests and procedures that are considered standard medical care.
A clinical study is a research study that explores whether a medical strategy, treatment, or device is safe and effective for people. These studies are used to produce the best data available for healthcare decision making.
Clinical studies follow strict scientific standards. These standards protect patients and help produce reliable study results. The clinical study may find that a new strategy, treatment, or device improves patient outcomes, offers no benefit, or causes unexpected harm. All of these results are important because they advance medical knowledge and help improve patient care.
