Abstract: An inflatable medical instrument (18) for tissue damage in gastric reduction surgery includes a main chamber (20) composed of a biocompatible material capable of being selectively inflated. The medical instrument also includes a longitudinally extending tab member (26) secured to an outer surface of the main chamber, a series of suction holes (30) are formed along the tab member and an electrode (38) is mounted on the tab member. The present invention also provides a method for forming a tissue junction used in defining a gastric pouch including damaging opposed tissue layers, apposing the tissue layers and fastening the tissue layers to allow the tissue layers to heal together.

Abstract: A surgical instrument includes an ablation device. The ablation device includes an elongated flexible member having a proximal end and a distal end. The flexible member includes first and second lumens. A first needle electrode is configured to slideably move within the first lumen. A second needle electrode is located within the second lumen. The first and second needle electrodes are adapted to couple to an electrical waveform generator and to receive an electrical waveform sufficient to electrically ablate tissue located between the first and second needle electrodes. A clamp jaw portion may be located at the distal end of the elongated flexible member. The clamp jaw portion is operatively movable from an open position to a closed position. A cutting blade may be located in the clamp jaw portion. A blunt dissection portion may be formed on the clamp jaw portion. The clamp jaw portion is adapted to couple to an electrical waveform generator and to receive an electrical waveform.
