一種新型射頻消融系統被用于經由皮膚手術、經腹腔鏡手術以及手術中的組織凝固以及消融，比如用于不能切除肝臟病變的部分或者完全消融治療。

Cool-tip射頻消融系統允許內科醫生使用射頻消融電流治療不適合外科手術的患者、或者不能使用其它方法治療的患者。該系統是由Valleylab公司研制開發的，該公司是Tyco保健中心的商業機構。

Cool-tip射頻消融系統聯合使用新型射頻消融電流、有效加熱凝固大塊組織并冷卻的內部電極。在消融過程中，有17線規內部循環水的電極冷卻暴露于電極的相鄰組織，最大程度傳送能量而最小程度焦灼組織。除此之外，系統的發電機軟件可以監測組織電阻從而相應調節輸出能量。

Valleylab是一家先進的基于能量醫療系統的制造商，產品包括電子外科手術發電機、附屬設備以及一次性產品、血管縫合系統、患者返還式電極、氬增強電子外科手術系統、經皮膚檢查設備、以及射頻治療系統。

RF Ablation for Nonresectable Liver Lesions
 
A new radiofrequency (RF) ablation system is for use in percutaneous, laparoscopic, and intraoperative coagulation and ablation of tissue, such as the partial or complete ablation of nonresectable liver lesions.

Using an RF current, the Cool-tip RF ablation system allows physicians to treat patients who are not suitable surgical candidates or are otherwise unable to be successfully treated with other methods. The system was developed by Valleylab (Boulder, CO, USA; www.valleylab.com), a business unit of Tyco Healthcare.

The Cool-tip RF system utilizes a novel combination of RF current and internal electrode cooling to effectively heat and coagulate large volumes of tissue. During the ablation process, the 17-guage electrode internally circulates water to cool the tissue adjacent to the exposed electrode, maximizing energy deposition and minimizing tissue charring. In addition, the system's generator software monitors tissue impedance and adjusts the output accordingly.

Valleylab is a manufacturer of advanced energy-based medical systems, including electrosurgical generators, accessories, and disposable products, a vessel sealing system, patient return electrodes, argon-enhanced electrosurgery systems, laparoscopic instruments, and RF treatment systems.
