1. A tissue treatment assembly configured to engage and disengage with an electrosurgical unit having a source of radio-frequency energy, the tissue treatment assembly, comprising:
a shaft including an elongated conductor having a proximal end portion and a distal end portion, the distal end portion including an electrode, wherein at least a section of the elongated conductor is a hollow shaft;
a handle operably coupled to the shaft to enable a user of the tissue treatment assembly to hold and manipulate the tissue treatment assembly by hand;
a cartridge member formed from an electrically insulating material and associated with the proximal end portion of the shaft and the handle, the cartridge member including:
an identifier circuit including a printed circuit board having a circuit element configured to afford communication of a signal from the tissue treatment assembly to the electrosurgical unit, wherein the signal is configured to identify a parameter of the tissue treatment assembly, an identifier number of the tissue treatment assembly, and an operating relationship between fluid flow settings and power delivery settings over a range of power delivery settings as tissue treatment information, the tissue treatment information stored on the identifier circuit, the signal may be received by the electrosurgical unit as a stream of data to the electrosurgical unit, wherein the tissue treatment information in the signal automatically configures the electrosurgical unit in a default power delivery and default fluid flow setting provided to the tissue treatment assembly; and
a portion of a control circuit couplable to the elongated conductive portion, the control circuit having an electrical input configured to receive radio-frequency energy based on the parameter from the source of radio-frequency energy and configured to provide the radio-frequency energy to the elongated conductive portion; and
a switch disposed between the electrical input and the electrode, the switch transitionable between an open position and a closed position, wherein the closed position enables radiofrequency energy to reach the electrode, and wherein the open position prevents radio-frequency energy from reaching the electrode.
