New RFA System for Larger Tumors

A new radiofrequency ablation (RFA) system has been developed that has the capacity to destroy larger liver tumors faster. The system was introduced at the annual meeting of the Radiological Society of North America (RSNA) in Chicago (IL, USA).

The new system is designed to provide a large, scalable, spherical ablation, thereby reducing or eliminating the need for overlapping ablations and minimizing the time it takes to perform the procedure. Developed by Rita Medical Systems, Inc. (Mountain View, CA, USA), the system can ablate a tissue volume of up to seven cm in diameter, about the size of a tennis ball. Called the StarBurst Xli, the system uses the company's micro-infusion technology to deliver tiny drops of fluid to the tips of the RF electrodes to aid the ablation process.

"While we currently target unresectable liver lesions, promising clinical studies on the use of our technology in lung, breast, and bone cancers are under way,” said Barry Cheskin, president and CEO of Rita Medical Systems.
