MRI-guided laser ablation for healthcare professionals

MRI-guided laser ablation coagulates and necrotizes unwanted tissue in the brain. The Visualase™ MRI-guided laser ablation system consists of a small laser catheter that delivers light energy to the target area. As that light is delivered, the temperature in the target area begins to rise and is observed under real-time MRI imaging — allowing the surgeon precise control of the ablation. After the procedure, the small incision can usually be closed with a single suture,1,2 and in many cases the patient can return home the next day.3-8

Epileptic foci ablation

Your medically-refractory focal epilepsy patients may benefit from Visualase™ MRI-guided laser ablation. FDA-cleared to ablate epileptic foci, this minimally invasive surgical option may ultimately help patients manage their seizures when medication alone may not work.


Brain tumor ablation

Your primary and metastatic brain tumor patients may benefit from Visualase™ MRI-guided laser ablation. FDA-cleared to ablate tumors in the brain, this minimally invasive surgical option may ultimately help patients to a speedier recovery for the continuation of their treatment.

Learn more about Visualase™ MRI‑guided laser ablation

Visualase™ MRI-guided laser ablation has been used by neurosurgeons since 2007 for precise and controlled necrotization and coagulation of soft tissue in the brain. Learn more about Visualase™ technology, equipment, and workflow.
