Radiofrequency ablation (RFA), also called fulguration, [1] is a medical procedure in which part of the electrical conduction system of the heart, tumor, sensory nerves or a dysfunctional tissue is ablated using the heat generated from medium frequency alternating current (in the range of 350–500 kHz).
Catheter ablation is a procedure that uses radio-frequency energy or other sources to terminate or modify a faulty electrical pathway from sections of the heart of those who are prone to developing cardiac arrhythmias such as atrial fibrillation, atrial flutter and Wolff-Parkinson-White syndrome.
Medical applications of radio frequency (RF) energy, in the form of electromagnetic waves (radio waves) or electrical currents, have existed for over 125 years, [1] and now include diathermy, hyperthermy treatment of cancer, electrosurgery scalpels used to cut and cauterize in operations, and radiofrequency ablation.

Targeted radiofrequency ablation (also written t-RFA) is a minimally invasive procedure to treat severe pain and discomfort caused from metastatic tumors in the vertebral body of the spine. This procedure uses radiofrequency energy to target and ablate a specific spinal tumor, causing it shrink and reduce the pressure on the surrounding nerves ...
Medical applications of radio frequency (RF) energy, in the form of electromagnetic waves (radio waves) or electrical currents, have existed for over 125 years, [9] and now include diathermy, hyperthermy treatment of cancer, electrosurgery scalpels used to cut and cauterize in operations, and radiofrequency ablation.

The device uses radiofrequency or ultrasound to ablate the renal nerves. Typically, numerous ablations are applied at a different longitudinal and rotational positions to ensure maximal denervation. [13] The procedure does not involve a permanent implant. [citation needed]
Transurethral needle ablation can be used to treat benign prostatic hyperplasia (BPH). [4] Some clinical studies have reported that TUNA is safe and effective, improving the urine flow with minimal side effects when compared with other procedures, such as transurethral resection of the prostate (TURP) and open prostatectomy.
Pulsed radiofrequency is the technique whereby radio frequency (RF) oscillations are gated at a rate of pulses (cycles) per second (one cycle per second is known as a hertz (Hz)). Radio frequency energies occupy 1.0 × 10 4 Hz to 3.0 × 10 11 Hz of the electromagnetic spectrum .
