Darrin Uecker, CTO, Assumes Operations Responsibilities, Trent Reutiman Named Vice President, Sales and Marketing

Mountain View, Calif., August 30, 2004—RITA Medical Systems, Inc. (Nasdaq: RITA), a leader in medical oncology devices, today announced that RITA Chief Technology Officer, Mr. Darrin Uecker, will assume all operations responsibilities for the company, and that Mr. Trent Reutiman has been named Vice President, Sales and Marketing. Mr. Uecker will assume the operations responsibilities of Mr. Robert Wenzel, who is leaving the company to pursue other opportunities.

Mr. Joseph DeVivo, President and Chief Executive Officer of RITA Medical commented, "I am extremely pleased with the progress we have made integrating our vascular access and radiofrequency ablation businesses. We will continue to focus on delivering the best technology in the market and on developing the best sales and marketing organization in the category. I am confident that we have an excellent team in place to build RITA into a world leader in the medical oncology device market."

Mr. Uecker will lead the company’s operations functions, assuming all of the operations responsibilities for the company’s vascular access products (VAP). In addition, Mr. Uecker will have overall responsibility for research and development, clinical affairs, quality assurance, and all regulatory activities. Prior to joining RITA, Mr. Uecker was Chief Operating Officer at Computer Motion, a Santa Barbara based developer of robotic surgical systems. Mr. Uecker led that company’s integration efforts during the 2003 merger with Intuitive Surgical, a Sunnyvale based maker of surgical robotic systems. Since the announcement of the merger between RITA Medical and Horizon Medical, Mr. Uecker has led the integration of the Mountain View, California and Manchester, Georgia operations and is responsible for completing the relocation of manufacturing of the company’s radiofrequency ablation (RFA) products to the Georgia facility. Mr. Uecker reports directly to Mr. DeVivo.

Mr. Uecker commented, "The responsiveness and professionalism of the staff in Manchester has been extremely gratifying. They have proven that they have the ability to make the transition to manufacturing both product lines at the facility very smooth. We expect to complete the transition on or ahead of our intended schedule in the first quarter of next year."
