Brain Tumor Visualase Laser Treatment

The Visualase System is an MRI-guided, minimally invasive laser ablation system which allows monitoring of the ablation in real time. The system is FDA-cleared for the ablation of soft tissue including use in neurosurgical procedures.

The Visualase System utilizes a laser to destroy soft tissue. Light energy is delivered to the target area using a laser applicator. As light is delivered through the laser applicator temperatures in the target area begin to rise, destroying the unwanted tissue.

How it works

  1. In the operating room, the laser applicator is placed through a small cranial access.
  2. The patient is then placed into an intra-operative MRI unit. Laser applicator position is confirmed with imaging and a low power test dose. During therapy, clinicians can control ablation volume while monitoring real-time temperature imaging and damage model.
  3. Laser applicator is removed and the incision is closed, typically with a single stitch. Most patients are discharged after a shorter stay as compared to open procedures.


  • Destruction of targeted tissue through a minimally invasive technique instead of a craniotomy
  • Minimal sutures required, typically a 1-stitch suture
  • Most patients are discharged after a shorter stay as compared to open procedures
  • Reduced scarring compared to open procedures
