Abstract
An electrosurgical instrument is disclosed for the treatment of tissue in the presence of an electrically-conductive fluid. The instrument comprises an instrument shaft, and a tissue treatment electrode at one end of the shaft, the tissue treatment electrode being constructed to define thermal barriers for limiting thermal conduction therealong, thereby to encourage the formation and maintenance of a layer of vapor over the electrode.
