    Abstract: An apparatus and method for use in performing ablation of organs and other tissues includes a radio frequency generator which provides a radio frequency signal to ablation electrodes. The power level of the radio frequency signal is determined based on the subject area of ablation. The radio frequency signal is coupled with the ablation electrodes through a transformation circuit. The transformation circuit includes a high impedance transformation circuit and a low impedance transformation circuit. The high or low impedance transformation circuit is selected based on the impedance of the ablation electrodes in contact with the subject tissue. Vacuum level, impedance level, resistance level, and time are measured during ablation. If these parameters exceed determinable limits the ablation procedure is terminated.

    Abstract: A method and apparatus for treating tissue using an electrosurgical system. The system includes an electrosurgical system having an RF generator, a treatment electrode electrically coupled to the RF generator and positioned in contact with target tissue to be treated, and a spark gap switch positioned between the RF generator and the target tissue. The spark gap includes a threshold voltage and is configured to prevent conduction of current from the RF generator to the tissue until the voltage across the spark gap reaches the threshold voltage. The method includes the steps of using the RF generator to apply a voltage across the spark gap switch, the spark gap switch causing conduction of current from the RF generator to the target tissue once the voltage across the spark gap reaches the threshold voltage.

    Abstract: A surgical system for controlled application of ultrasound energy to engaged tissue volumes for creating effective biological welds or seals in tissue. The invention provides an ultrasound transmission assembly including piezoelectric elements coupled to an elongate waveguide that is reciprocatable in an interior of an introducer. The reciprocatable waveguide assembly of the invention is adapted to have multiple functionality: (i) to couple ultrasound energy to both opposing jaws to thereby deliver energy to both sides of engaged tissues to create uniform thermal weld effects; (ii) to apply very high compressive forces to captured tissues over the length of elongate jaws by engaging substantially the entire length of the jaws, and (iii) to transect the captured tissues contemporaneous with the delivery of energy to create the thermal weld. The invention further provides for use of other energy sources to deliver thermal energy to tissue, for example microwave energy, Rf energy and laser energy, either in combination with ultrasound energy or independently.
