  • Patent number: 10639098
    Abstract: This invention relates to high-frequency ablation of tissue in the body using a cooled high-frequency electrode connected to a high frequency generator including a computer graphic control system and an automatic controller for control the signal output from the generator, and adapted to display on a real time graphic display a measured parameter related to the ablation process and visually monitor the variation of the parameter of the signal output that is controlled by the controller during the ablation process. In one example, one or more measured parameters are displayed simultaneously to visually interpret the relation of their variation and values. In one example, the displayed one or more parameters can be taken from the list of measured voltage, current, power, impedance, electrode temperature, and tissue temperature related to the ablation process.

  • Patent number: 10631915
    Abstract: An RF electrode can have a straight shaft to generate an RF heat lesion that is asymmetric about the central axis of the cannula through which the RF electrode is introduced into bodily tissue. For example, system for tissue ablation including a cannula and an electrode, the cannula including an elongated shaft having a proximal end and a distal end, the cannula shaft including an electrically conductive active tip distal to an electrically insulated cannula shaft portion, the cannula shaft including a lumen extending from a proximal opening at the proximal end of the shaft to a distal portion of the shaft.

  • Patent number: 10136943
    Abstract: An RF electrode can have a straight shaft to generate an RF heat lesion that is asymmetric about the central axis of the cannula through which the RF electrode is introduced into bodily tissue. An electrode can be inserted into a cannula, and an electrosurgical generator can apply current between the active tip of the electrode and the active tip of the cannula to heat tissue.
