  • Electrosurgical instrument having a chamber to volatize a liquid
    Patent number: 6699244
    Abstract: An electrosurgical instrument is provided which includes a holding formation, a probe shaft, an electric conductor, and a probe tip. The probe shaft is secured to the holding formation and has an elongated section extending therefrom. The electric conductor extends along the elongated section. The probe tip is located on a distal end of the probe shaft opposing the holding formation. The probe tip defines a volatization chamber with a mouth out of the probe tip. The probe tip includes an electrode, to which RF current is provided through the electric conductor. The electrode heats an area adjacent to the probe tip. The electrode also heats a liquid in the first volatization chamber to evaporate the liquid into a vapor pocket that ejects from the first volatization chamber through the mouth out of the probe tip. A pump effect is created so that the liquid maintains the probe tip at a more stable temperature.
    Type: Grant

  • Electrode for electrosurgical ablation of tissue
    Publication number: 20030014050
    Abstract: An electrosurgical probe is provided to vaporize, cut, coagulate or remove tissue from a body structure. A method of surgically treating a mammal includes providing a surgical instrument including a length of shaft and an active electrode having a curved current density edge with at least one convex surface; and ablating a tissue surface with said surgical instrument.
