About RITA Medical Systems

RITA Medical Systems develops, manufactures and markets innovative products that provide local oncology therapy options for cancer patients including radiofrequency ablation (RFA) systems and embolization products for treating cancerous tumors, as well as percutaneous vascular and spinal access systems for systemic treatments. The company's oncology product lines include implantable ports, some of which feature its proprietary Vortex® technology; tunneled Central Venous Catheters; and safety infusion sets and peripherally inserted central catheters used primarily in cancer treatment protocols. The company's complete line of radiofrequency products also includes the Habib 4X resection device and will include the new Laparoscopic Habib 4X resection device, both of which are designed to coagulate highly vascularized tissue to facilitate a fast dissection in order to minimize blood loss and blood transfusion during surgery. The proprietary RITA RFA system uses radiofrequency energy to heat tissue to a sufficiently high temperature to ablate it or cause cell death. In March 2000, RITA became the first RFA company to receive specific FDA clearance for unresectable liver lesions in addition to its previous general FDA clearance for the ablation of soft tissue. In October 2002, RITA became the first company to receive specific FDA clearance for the palliation of pain associated with metastatic lesions involving bone. The company also distributes LC Bead embolic microspheres in the United States. The LC Bead microspheres are injected into selected vessels to block the blood flow feeding a tumor, causing it to shrink over time, and are often used in combination with RFA.
