Abstract
A cooled electrosurgical system includes an electrosurgical device having at least one electrode for applying electrical energy to tissue. In one embodiment, the electrode includes an internal cavity in which a cooling medium such as water is contained. The internal cavity is closed at the distal end of the device such that the cooling medium is contained within the electrode at the surgical site such that the cooling medium does not contact the tissue being treated.
