Radiofrequency Ablation for Arthritis Pain. Radiofrequency ablation (or RFA) is a procedure used to reduce pain. An electrical current produced by a radio wave is used to heat up a small area of nerve tissue, thereby decreasing pain signals from that specific area.
Catheter ablation is a procedure in which a small catheter is placed inside the heart (via a leg vein). The catheter has a 4-8 mm metal tip through which radio-frequency (or cryothermal) energy is delivered to selected parts of the heart.
