Abstract

An electrosurgical apparatus for coagulating tissue comprises an elongate tube (3) having a proximal end and a distal end, and having a distal end face (12). The tube comprises one or more first apertures (14) located at the distal end face (12) and one or more second apertures (13) located along the periphery of the tube between the proximal and distal ends. The tube provides a conduit though which ionizable gas can be supplied to the distal end of the tube, and includes at least one electrode (4) for ionizing the ionizable gas exiting either the first or second apertures.
