About RITA Medical Systems, Inc.

RITA Medical Systems develops, manufactures and markets innovative products for patients with solid cancerous or benign tumors. The proprietary RITA system uses radiofrequency energy to heat tissue to a high enough temperature to ablate it or cause cell death. While the Company's current focus is on liver cancer, the Company believes that its minimally invasive technology may in the future be applied to other types of tumors, including tumors of the lung, bone, breast, uterus, prostate and kidney. The Company has received regulatory clearance in major markets worldwide, including the United States. In March 2000, RITA became the first radiofrequency ablation company to receive specific FDA clearance for unresectable liver lesions in addition to its previous general FDA clearance for the ablation of soft tissue. The Company has sold over 35,000 of its disposable devices throughout the world.

The statements in this news release related to the Company's plans to extend its technology to applications beyond the liver are forward-looking statements involving risks and uncertainties that could cause actual results to differ materially from those in such forward-looking statements. Potential risks and uncertainties could include, but are not limited to, the Company's dependence on timely market acceptance of the RITA system, the outcome of current patent actions and the Company's reliance on clinical data developed independently by third party physicians. Further information regarding these and other risks is included in the Company's filings with the Securities and Exchange Commission.
