Preparation of nanoparticles by Laser in Solution. Laser ablation is the process of removing material from a solid (or occasionally liquid) surface by irradiating it with a laser beam. At low laser flux, the material is heated by the absorbed laser energy and evaporates or sublimates. At high laser flux, the material is typically converted to a plasma.
Ablation surgery has become one of the most effective methods in treating atrial fibrillation, especially in patients who do not respond to drug treatment. Definition of Ablation Surgery Ablation surgery is a procedure to destroy abnormal tissues. It is often used in patients who have extra tissue in their hearts that creates abnormal electrical impulses. These impulses interfere with the heart's normal electrical stimulating tissue, and this results in atrial fibrillation, or the quivering of the upper chambers of the heart.
