  • Electrical discharge devices and techniques for medical procedures
    Patent number: 7220261
    Abstract: A medical instrument coupled to first and second energy means and a computer controller for the controlled volumetric removal of thin tissue layers. The system provides a source for introducing a gas to controllably form and capture transient gas volumes in a microchannel structure at the working surface of the instrument that interfaces with a targeted tissue site. Each of the microchannel features of the working surface carries an electrode element coupled to the electrical source. The energy may be applied to the targeted site in either of two modes of operation, depending in part on voltage and repetition rate of energy delivery. In one mode of energy application, electrical potential is selected to cause an intense electrical arc across the transient ionized gas volumes to cause an energy-tissue interaction characterized by tissue vaporization.

  • Voltage threshold ablation apparatus
    Publication number: 20050228372
    Abstract: The present invention relates to the field of electrosurgery, and more particularly to systems and methods for ablating, cauterizing and/or coagulating body tissue using radio frequency energy. More in particular, the systems utilize voltage threshold means for controlling the voltage applied to tissue in a cycle-to-cycle manner.
