High intensity ablation device
First Claim
1. An apparatus for ablating tissue, the apparatus comprising:
- first and second opposing jaws operative to secure tissue to be ablated therebetween;
the first jaw having a first ablation surface for directing ablative energy into the tissue;
the second jaw having a second ablation surface for reflecting ablative energy into the tissue; and
at least one of the first jaw or the second jaw having a cavity with a transducer element therein and an air backing chamber.

Abstract
An apparatus for ablating tissue, the apparatus having first and second opposing jaws operative to compress tissue to be allayed therebetween, the first jaw having a first ablation surface directing ablative energy into the tissue and the second jaw having a second ablation surface reflecting incident ablative energy into the tissue. The ablative energy may be ultrasonic, microwave, cryoablation, radio-frequency, photodynamic, laser, and cautery energy. The instrument may also have a pointed tip for piercing tissue, allowing the instrument to clamp the tissue wall of a hollow organ before ablation. Alternately, the instrument may clamp two or more tissue layers of a hollow organ without piercing prior to clamping an ablation.
