RITA’s patented electrosurgical delivery method, known as the RITA System uses deployable radiofrequency (RF) electrode arrays to raise the temperature of cells above 45 to 50°C and cause cellular death. The RITA System includes radiofrequency generators and a family of electrosurgical devices that deliver controlled thermal energy to the targeted tissue.

Used by surgical oncologists, hepatobiliary surgeons, liver transplant surgeons, laparoscopists and interventional radiologists, the RITA System offers patients with unresectable liver lesions an effective treatment option with few side effects or complications. The RITA System is also cleared for use as a pain relief method for patients with metastatic bone lesions.
