Abstract

An electrosurgical probe and method for using the same is provided. The electrosurgical probe includes a distal end and a proximal end, with the distal end having a configuration defining an outer convex face (102) and an inner concave face (104). At least one active electrode (110) and at least one return electrode (120) are mounted on the inner concave face.
