FDA clears Varian Trilogy for stereotactic radiosurgery

Varian Medical Systems has received FDA 510(k) clearance that permits the use of the company's Trilogy linear accelerators for stereotactic radiosurgery. The clearance also marks the introduction of Varian's new Trilogy Tx Image-Guided Radiosurgery (IGRS) model designed specifically for surgeons, the company said.

Both the Trilogy and Trilogy Tx machines now can be used for stereotactic radiosurgery as well as precision radiotherapy for lesions, tumors, and conditions anywhere in the body when radiation treatment is indicated.

"With this new clearance, physicians can begin to provide Trilogy Treatments for functional lesions like trigeminal neuralgia and other non-cancerous conditions," said Lester Boeh, vice president and general manager, Varian Surgical Sciences. "The prior FDA clearance for the Trilogy device was limited to benign and malignant cancers, and arteriovenous malformations.
