The NeuroBlate® System is a minimally invasive robotically controlled laser thermotherapy that uses MRI-guided laser light to ablate (destroy) unwanted tissue in the brain where the lesion, or abnormal tissue originates.

NeuroBlate is a minimally invasive procedure, a type requiring only a small opening in the body instead of a large incision as in open surgery. Generally, minimally invasive procedures:

  • Are well tolerated
  • Have a short recovery time
  • Have nominal incision-patients go home with 1‑2 stitches


Explore what to expect before, during, and after ablation with the NeuroBlate System.


Pre-Surgical Evaluation

Prior to having brain surgery, a surgical evaluation is necessary. The specific pre-operative tests depend on the type of surgery but may include:

  • Full health assessment.
  • Evaluation of the brain lesion and the surrounding brain tissue.

Your doctor will advise you of any pre-procedure requirements such as potentially stopping medications or avoiding food and drink prior to the procedure.

Pre-Surgical Evaluation


You will receive anesthesia before the procedure. Your doctor will determine what level of anesthesia is right for you. With the NeuroBlate System, doctors create a small hole in the skull, about the diameter of a pencil. While the patient is in the MRI machine, the doctor guides a small laser device (probe) through the hole into the brain lesion. The probe delivers laser light energy (laser ablation) that heats and destroys the affected tissue.

  • Because the NeuroBlate System is MRI-guided, the neurosurgeon is able to visualize the specific area of the brain to be ablated. The precise nature of the procedure helps to lessen the likelihood of harm to nearby healthy brain tissue.1

  • Generally, minimally invasive procedures are well tolerated and have a short recovery time.


  • You will have 1-2 stitches to close the incision.
  • You may also have scratches on your head from the device that helps keep your head in position.

Follow-up Appointment(s):

  • You will schedule follow-up appointment(s) with your doctor as instructed.

Each patient is unique. Your doctor(s) are the best qualified to describe specifically how a procedure may affect your outlook.


The NeuroBlate System is a surgical tool used in brain surgery to heat and destroy targeted brain tissue associated with tumors, radiation necrosis, or epilepsy. Patients must be able to undergo MRI exposure. All brain surgeries carry risk. Possible adverse events include, but are not limited to, bleeding, edema, unintended major brain tissue damage, and permanent neurological deficits. Discuss the potential benefits and risks with your physician.
