An electrosurgical wand is disclosed. The electrosurgical wand includes a handle that defines a proximal end of the electrosurgical wand. The electrosurgical wand includes an elongate shaft coupled to the handle; the elongate shaft defines a suction lumen therein. The electrosurgical wand also includes an electrically insulative spacer (404) coupled to the distal end of the elongate shaft, whereby the spacer defines a suction channel (412) fluidly coupled to the suction lumen. The electrosurgical wand includes a first means for blocking defined by the spacer, an active electrode (402) coupled on the distal end of the spacer and a second means for blocking associated with the active electrode and in operational relationship to the first means for blocking. In the electrosurgical wand, the first means for blocking includes an annular trough (416) that fully encircles the suction channel of the spacer and the second means for blocking includes an annular wall (414).
