RITA Medical Systems introduces radiofrequency ablation device for tumours

4 April 4 2005

RITA Medical Systems, Inc. (NASDAQ:RITA) has introduced the StarBurst TALON, a radiofrequency ablation (RFA) device that offers clinicians the ability to perform fast 4cm spherical ablations with a novel side-deploy design that assists precise device positioning in tumours that may be mobile in soft tissue or adjacent to critical structures.

The new TALON side-deployed electrode was introduced at the 30th Annual Scientific Meeting of the Society of Interventional Radiology (SIR), 31 March – 5 April 5, 2005, in New Orleans. The TALON delivers an easy to use product solution for non-staged deployed ablations compatible with the company's infusion system family of products that use the Intelliflow pump to deliver precise amounts of saline to the ablation site.

The TALON electrode, now available for sale in the United States and Europe, builds on RITA Medical's clinical experience in local control of cancerous tumours using radiofrequency ablation. TALON is cleared by the U.S. Food and Drug Administration for use in partial or complete ablation of non-resectable liver lesions and the palliation of pain associated with metastatic lesions in patients who have failed or are not candidates for standard therapy. The TALON is labeled with the CE Mark for distribution in Europe.

The Starburst Talon may be used in laparoscopic, percutaneous or open procedures and includes several novel usability features:

  • Fast 4 cm spherical ablation possible in as little as 9 minutes after reaching the target temperature using the RITA Infusion System and Intelliflow(TM) pump.
  • A unique tapered cutting tip center electrode to make it easier to penetrate solid tumors.
  • Easy to position for both surface and difficult to reach dome lesions.
  • Semi-flexible 900 bendable version available (TALON Semi-Flex(TM)) that makes entry into CT (Computed Tomography) imaging gantry possible without sacrificing electrode penetration depth.
  • Proprietary real-time temperature feedback from all four electrode tines ensures controlled ablation

RITA Medical products have been used in more than 75,000 ablation procedures. Radiofrequency ablation allows physicians to deliver radio frequency electrodes directly into cancerous tumours through a thin probe. The electrodes are commonly introduced in a minimally invasive manner to heat and effectively destroy, or ablate, the targeted area. RITA RF ablation is performed on patients with tumours of the liver, bone, and soft tissue, and is normally used in conjunction with chemotherapy, or radiation treatments.
