04074718 is referenced by 538 patents and cites 11 patents.

An electrosurgical instrument comprising a support member; at least one electrode mounted on the support, the electrode consisting essentially of a material having a figure of merit of at least 0.15 at room temperature where the figure of merit is the product of the thermal conductivity, the heat capacity and the density of the material in the metric system; and a heat sink in thermal contact with the electrode for removal of heat therefrom. A carbon coating for the electrode is also disclosed where the coating may be formed by different techniques including thermal decomposition of certain carbohydrate containing materials, the latter method providing a porous carbon coating particularly suited for expediting the starting of the instrument. Also disclosed are a number of heat sinks for effecting removal of heat from the electrode. Further disclosed is a monolithic blade made from carbon.
