An electrosurgical apparatus for coagulating tissue used in combination with an endoscope which includes an elongated flexible tube having a plurality of side-ports located therethrough. The tube extends through a working channel of the endoscope and an ionizable gas is supplied to the tube at or near the proximal end of the tube. A diffusing member directs the ionizable gas from the proximal end of the tube through each of the side-ports towards the tissue. An electrode is used for ionizing the gas prior to the gas exiting the side-ports.

Un appareil électro-chirurgical de coagulation de tissu utilisé avec un endoscope et qui comprend un tube souple allongé muni d'une pluralité d'orifices latéraux. Le tube se prolonge dans un canal de travail de l'endoscope et un gaz ionisable est injecté dans le tube à son extrémité proximale ou près de celle-ci. Une chambre de diffusion dirige le gaz ionisable de l'extrémité proximale du tube en direction du tissu en le faisant passer dans chacun des orifices latéraux. Une électrode sert à ioniser le gaz avant sa sortie des orifices latéraux.
