21. Radiofrequency waves and ultrasound can be used for temporary blocking of peripheral nerves during neurosurgical operations.22. Halyard Health was awarded Innovative Technology Designation for Coolief Cooled Radiofrequency Treatment at Novation Expo 2015. 23. It is performed without surgery, by using radiofrequency catheter ablation with one-day hospital. 24. Targeted radiofrequency ablation is not a treatment for cancer, but is used for pain management. 25. Thyroid radiofrequency ablation is one of the minimally invasive treatment methods that selectively treats thyroid nodules. 26. The definitive treatment of WPW is a destruction of the abnormal electrical pathway by radiofrequency catheter ablation. 27. The first airways to be delineated by radiofrequency were based on the old A-N system. 28. In 2004, former British prime minister Tony Blair underwent radiofrequency catheter ablation for recurrent atrial flutter. 29. This treatment which works with a natural agent ( water ) has similar results than laser or radiofrequency . 30. Frequent attacks may require radiofrequency ablation, in which the abnormally conducting tissue in the heart is destroyed.
