| description | An electrosurgical return electrode for use in electrosurgery. The return electrode is self-limiting and self-regulating as to current temperature and temperature rise so as to prevent patient trauma. According to one aspect of the invention, an inductor is coupled in series with the electrosurgical return electrode. The inductor is configured to optimize the flow of the electrosurgical current by minimizing the effective bulk impedance of the electrosurgical return electrode when the amount of contact area between the patient and the electrosurgical return electrode is sufficient to conduct electrosurgery. According to another aspect of the present invention, a conductor member is adapted for use with circuitry that indicates to a user when the contact area between the patient and the self-limiting member and/or return electrode is below a given threshold. |
