摘要:
An electrical surgical cautery device for delivering thermal energy to cauterize and provide hemostasis to a bleeding tissue comprises an electrically powered flexible thermal delivery element having a substantially planar resistive coil embedded in a thermally conductive material. The thermally conductive material comprises a tissue contact surface and a non-tissue contact surface. A power source is connected to the resistive coil of the thermal delivery element and provides an electrical current to heat the thermal delivery element being pressed against the tissue. A method for providing hemostasis to a bleeding tissue surface comprises providing and pressing an electrical cautery device having a thermal delivery element, against the hemorrhaging tissue at a predetermined temperature for an interval sufficient to cauterize the tissue and provide hemostasis.
