Abstract
An electrosurgical instrument is provided, having a holding formation, an elongated probe, an electrode, and a conductor. The elongated probe is connected to and extends from the holding formation. The electrode is located on an end of the elongated probe opposing the holding formation, and has a leading edge and a face. The electrode is locatable so that the face is substantially in a horizontal plane and the leading edge is above the horizontal plane. The conductor extends along the elongated probe and has a portion connected to the electrode to provide RF power thereto. The electrode creates a temperature profile with a temperature adjacent to the leading edge being higher than a temperature adjacent to the face.
