31. The most widely used ablation techniques for lung cancer are radiofrequency ablation, cryoablation, and microwave ablation. 32. The other device, which Humphrey tried, zaps the faulty valve with radiofrequency energy, beams of heat. 33. Radiofrequency ablation is frequently effective in reducing the severity of snoring, but often does not completely eliminate it.34. Radiofrequency catheter ablation is not performed in all individuals with WPW because inherent risks are involved in the procedure.35. Varicose veins can be treated with foam sclerotherapy, endovenous laser treatment, radiofrequency ablation, or open surgery. 36. A new and promising indication for the use of radiofrequency technology has made news in the last few years. 37. Therefore, the introduction of non-surgical means of renal denervation with radiofrequency ablation catheter was enthusiastically welcomed. 38. Like many heart-cauterizing instruments, the Ex-Maze device uses heat generated by a radiofrequency coil. 39. The most common form is an ablation of the pulmonary veins and surrounding tissue by means of radiofrequency energy. 40. Radiofrequency ablation is unproven, but to sit back and do nothing for a patient with liver cancer is unacceptable,
