Valleylab公司的射频消融系统可以治疗不能切除的肝脏病

一种新型射频消融系统被用于经由皮肤手术、经腹腔镜手术以及手术中的组织凝固以及消融，比如用于不能切除肝脏病变的部分或者完全消融治疗。

Cool-tip射频消融系统允许内科医生使用射频消融电流治疗不适合外科手术的患者、或者不能使用其它方法治疗的患者。该系统是由Valleylab公司研制开发的，该公司是Tyco保健中心的商业机构。

Cool-tip射频消融系统联合使用新型射频消融电流、有效加热凝固大块组织并冷却的内部电极。在消融过程中，有17线规内部循环水的电极冷却暴露于电极的相邻组织，最大程度传送能量而最小程度焦灼组织。除此之外，系统的发电机软件可以监测组织电阻从而相应调节输出能量。

Valleylab是一家先进的基于能量医疗系统的制造商，产品包括电子外科手术发电机、附属设备以及一次性产品、血管缝合系统、患者返还式电极、氩增强电子外科手术系统、经皮肤检查设备、以及射频治疗系统。

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.
