Abstract
A nozzle and electrode combination for use with an electrosurgical device is described. The nozzle includes a shroud defining a channel and a lumen which intersect to define an acute angle. An electrode is positioned within the channel and includes a distal end extending from a distal portion of the shroud and a proximal end extending from the proximal portion of the shroud. An end cap positioned adjacent the proximal portion of the shroud about the electrode is preferably overmolded to the shroud and the electrode. Preferably, a portion of the walls defining the channel and/or the lumen include conductive material which communicates with the electrode to eliminate electric potential within the shroud.
