Abstract

Abstract A method and apparatus for protected ablation of anatomical tissue. A protective cap is disposed around tissue within an anatomical cavity by an endoscopic device or through open surgery techniques. The tissue can then be subject to ablation at high energy for a relatively long period of time, if necessary to ablate the tissue, without damaging surrounding organs or other tissue. The protective cap can be inserted endoscopically in a closed position in which it is compact radially and can be opened after being inserted into the body cavity to be placed around the tissue. The protective cap can be a thermal insulator, an electrical insulator, merely a physical pad to protect surrounding tissue, or of any desired characteristic for protection.
