System components include a microprocessor-based RF generator, peristaltic pump, monopolar electrodes (single or cluster), inflow/outflow tubing, and return pads. Generator delivers up to 200W into 50 Ohm load; monitors tissue impedance, current, power, and electrode tip temperature via embedded thermocouples. Peristaltic pump circulates chilled sterile water through electrode tips to prevent charring; closed-loop cooling prevents water-patient contact. Used in percutaneous, laparoscopic, or intraoperative settings by physicians. Physician monitors real-time impedance and temperature data on generator display to guide energy delivery. Controlled thermal ablation enables destruction of non-resectable liver tumors, providing a minimally invasive alternative to surgical resection. ## Clinical Evidence Clinical evidence includes independent studies demonstrating the system is safe and effective for the ablation of primary and metastatic, unresectable liver tumors. Comparative in vivo and ex vivo product testing confirmed equivalence to currently marketed devices regarding coagulation and ablation of lesions. ## Technological Characteristics System comprises a microprocessor-based RF generator, peristaltic pump, and monopolar stainless steel electrodes. Features include closed-loop chilled water cooling, embedded thermocouples for temperature monitoring, and impedance-based energy control. Delivers up to 200W RF energy. Electrodes are sterile, single-use, and available in single or cluster configurations. ## Regulatory Identification An electrosurgical cutting and coagulation device and accessories is a device intended to remove tissue and control bleeding by use of high-frequency electrical current. ## Predicate Devices - Cool-tip™ RF System ([K042216](/device/K042216.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Submitter Information Valleylab A division of Tyco Healthcare Group LP 5920 Longbow Drive Boulder, CO 80301 Contact: Charles M. Copperberg Manager. Regulatory Telephone: 303-530-6247 Date summary prepared: November 23, 2005 #### 2. Name of Device Trade or Proprietary Name Cool-tip™ RF System Common/Classification Name. Electrosurgical Cutting and Coagulation Device and Accessories #### 3. Predicate Devices The Cool-tip™ RF System of this submission is substantially equivalent to the Cool-tip™ RF System covered by 510(k) notification K042216 dated 11/12/04. #### 4. Device Description The Cool-tip ™ RF System consists of a microprocessor based RF generator, a peristaltic pump, electrodes, inflow and outflow tubing for electrode cooling, and return pads. The generator pump and electrodes are designed to produce local tissue heating at the tip of the electrodes causing the coagulation (ablation) of the tissue. The Cool-tip ™ RF System generator is capable of delivering up to 200 watts (into a 50 Ohm resistive load) while monitoring tissue impedance and electrode tip temperature during the delivery of the RF energy The generator includes manual and impedance control and displays/monitors impedance. current, power and temperature. The Cool-tip™ RF System electrodes are available in either a single electrode or a cluster electrode configuration. The electrodes are monopolar devices. The cluster electrode is three electrode shafts combined into one handle in a triangular patter with approximately 0.5 cm separation. The electrodes are provided sterile, for single use only. The shaft of the electrode is stainless steel that is insulated to various lengths from the tip of the electrode. Embedded within the tip of each electrode is a thermocouple for temperature measurement. Cooling of the electrode is provided by chilled sterile water which is pumped (using the peristaltic pump) through the inflow tubing, the electrode and out through the outflow tubing. This is an enclosed system within the electrode and the sterile water does not contact the patient. Because of the 510(K) Notification Cool-tip ™ RF System November 23, 2005 {1}------------------------------------------------ # KOS3290 Page 2 of 2 monopolar nature of the electrodes, electrical current flows through the tip of the electrode, through the target tissue and to the return pad. #### 5. Intended Use The Cool-tip™ RF Ablation System (Generator and accessories) is intended for use in perculaneous, laparoscopic and intraoperative coagulation and ablation of tisser , such as partial or complete ablation of non-resectable liver tumors. #### દ. Summary of Technological Characteristics The Cool-tip™ RF System has the same basic technological characteristics as the predicate device noted above. #### 7. Performance and Clinical Data Comparative in vivo and ex vivo product testing has shown the Cool-tip™ RF System to be equivalent to currently marketed devices with regard to coagulation/ablation of lesions. Independent clinical studies have shown the use of the system to be clinically safe and effective for ablation of primary and metastatic, unresectable liver tumors. 510(K) Notification Cool-tip™ RF System November 23 2005 {2}------------------------------------------------ Image /page/2/Picture/1 description: The image shows the logo for the Department of Health and Human Services (HHS).
