Abstract
An electrosurgical electrode having a distal end for transferring the energy to the tissue and a thermal reservoir spaced apart from the distal end. The materials and shape of the electrode promote the flow of heat away from the distal tip so as to reduce the temperature of the tip during electrosurgery, to reduce tissue damage and to prevent the tissue from sticking to the electrode tip. The electrode is composed of a bio-compatible and highly thermally conductive metal, such as silver or gold of high purity, or alloy of those two metals. The shape provides a cross-sectional area that is constant or increasing as the distance from the tip increases. The rounded distal end transitions into a cylindrical section which then transitions into the thermal reservoir. The thermal reservoir is also cylindrical, having a cross-sectional area that is larger than the cross-sectional area of the first cylindrical section.
