一種新型射頻(RF)消融系統能夠為不能切除不適合手術的肝臟腫瘤患者提供一種微創治療方法。

Cool-tip系統是由Valleylab公司(Boulder, CO, USA)制造的，該公司是Tyco醫療保健集團(Mansfield, MA, USA)的分支，綜合了一種微處理器為基礎的RF發生器，通過17量規的內部冷針頭電極將200瓦RF能量直接輸送到腫瘤。使用CT或者超聲等影像學技術，引導針頭到消融部位。在消融過程中，使用水在內部循環以冷卻相鄰組織，從而能夠輸送最大RF能量，在最短時間內達到最大的消融效果。
 
Ablation System for Inoperable Hepatic Tumors
 

 
A new radiofrequency (RF) ablation system offers a minimally invasive alternative for patients with non-resectable hepatic tumors who are not ideal surgical candidates.

The Cool-tip system, manufactured by Valleylab (Boulder, CO, USA), a division of Tyco Healthcare Group (Mansfield, MA, USA), combines a microprocessor-based RF generator with a 17-gauge internally cooled needle electrode to deliver 200 watts of RF energy directly to the tumor. Imaging technology such as computed tomography (CT) or ultrasound is used to guide the needle to the ablation site. Water is circulated internally through the electrode during ablation to cool adjacent tissue, thereby maximizing delivery of RF energy and creating the largest ablation possible in a minimal amount of time.
