The present invetion provides a method and apparatus for elimination of atherosclerosis from an artery. According to the present invetion the diseased artery is approached from external side and ablate is approached in such a way that incision/cut pass through tunica adventitia and tunica media of the diseased artery and a fibrous capsule of the atherselerosis. On ablation/incision, the contents plaques are exposed to the natural defense of the body and are destroyed by the natural defense system. The plaque escaping out of the artery on the external surface of the artery may be wiped or washed away with saline during or after the ablation procedure. Then, natural healing of artery is allowed which eliminates atherosclerosis thoroughly.
