A plasma coagulation apparatus having end and side ports

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 a plurality of second apertures 13 located along the periphery of the tube between the proximal and distal ends. The tube provides a conduit though which ionisable gas can be supplied to the distal end of the tube, and includes at least one electrode 4, fig 4 for ionising the ionisable gas exiting either the first or second apertures.
