ABSTRACT:
A monopolar electrosurgical return electrode to prevent unwanted thermal effects in monopolar electrosurgery, accomplished in one aspect by volumetric incorporation of temperature-resistive material of positive nature into a flexible and adhesive return electrode pad is provided. The incorporation of positive temperature coefficient resistance with low resistance at room temperature will increase the local electrical resistance of the pad with an increase of the local return electrode temperature corresponding to a switching of the resistance from low to high value which in turn will lead to a reduction of the local current density. The switching temperature of the positive temperature coefficient return electrode is low enough to prevent significant thermal heating of the patient's tissue.
