<p>A self-limiting electrosurgical electrode for use with electrosurgery and various other surgical procedures is disclosed. The electrode includes a heating element for generating heat to warm a patient resting upon the electrode. The electrode can also include one or more pads to prevent the creation of pressure sores or decubitus ulcers on a patient resting upon the electrode. The electrode has an effective bulk impedance equal to or greater than about 4,000 O.cm, which arises from resistive components, capacitive components, inductive components, or combinations thereof. Through the selection of the impedance characteristics for the electrode materials, and through tailoring of electrode geometries, the electrode of the present invention is self-regulating and self- limiting as to current density and temperature rise so as to prevent patient trauma.</p> |
