Method and apparatus for controlling the areas of necrosis in the RF ablation technique

摘要

Relates to a method and apparatus for controlling the necrotic area during surgery using ablation techniques in tissue, tissue of constant volume is ablated by the action of heat utilizing electrospray catheter ablation. Method and apparatus are provided for using at least one sensor positioned corresponding to the peripheral zone of the tissue volume to be treated, to measure the electrical parameter based on the dehydration of the tissue.
