Abstract
An electrode tip for use in performing electrosurgical operative procedures is disclosed. The electrode tip includes a main body that can receive electrical energy from an electrosurgical generator. The main body includes a working surface that communicates the electrical energy to patient tissue during the operative procedure. An insulative sheath is disposed around a portion of the electrode tip to prevent electrical energy from being communicated from the covered portions of the electrode tip to patient tissue. The insulative sheath has a leading edge that is shaped to minimize resistance to the movement of the electrode tip through patient tissue. The leading edge can be arcuately shaped or angled relative to a longitudinal axis of the electrode tip to provide the resistance reducing characteristics.
