Ablation is the process of removal of undesired organs, abnormal growths or harmful substances from the human body. Ablation is the destruction of a nerve conduction pathway by the means of high frequency alternating currents, delivered by a bipolar or unipolar catheters. Radiofrequency (RF) ablation is a non-surgical procedure which utilizes radio waves or electric currents to interfere with the nerve conduction for a period of around six to nine months. Heat is generated from medium frequency alternating current in the range of 350-500 kHz. During radiofrequency ablation, a guiding needle reaches the desired tissue with the help of image guidance device such as a CT scan.
