Abstract
An RF electrode can have a straight shaft to generate an RF heat lesion that is asymmetric about the central axis of the cannula through which the RF electrode is introduced into bodily tissue. An electrode can be inserted into a cannula, and an electrosurgical generator can apply current between the active tip of the electrode and the active tip of the cannula to heat tissue.
