Laser interstitial thermal therapy (LITT) is a minimally invasive surgical technique that uses laser energy to heat and destroy (ablate) targeted tissue. It has been used in focal epilepsy, brain tumors, and radiation necrosis. The two most commonly used FDA-cleared LITT systems in the U.S. are Visualase and NeuroBlate. The Visualase system just received FDA 510k clearance for its next-generation platform - the Visualase V2 - which includes updates to the system's hardware, software, and workflow. This new version may enhance the precision and usability of LITT and help expand access to this treatment option.
