RITA Medical

RITA Medical Systems was a medical device company specializing in the development and commercialization of radiofrequency ablation (RFA) systems for the treatment of solid cancerous tumors. The company's core technology utilized a proprietary expandable electrode to deliver thermal energy directly into tumors, effectively destroying cancerous tissue while sparing surrounding healthy structures. Its flagship products, including the StarBurst family of RFA devices, were primarily used for treating unresectable liver, lung, and bone tumors. RITA Medical Systems was a pioneer in the interventional oncology space and was publicly traded on the NASDAQ. In 2007, the company was acquired by AngioDynamics, which integrated RITA's ablation portfolio into its broader oncology product line.
