  • Patent number: 10111703
    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: 9008793
    Abstract: A apparatus for performing tissue modification procedures on a patient's body can include a device, which can be adapted for connection to at least two electrodes, where temperature sensors can be incorporated into tip portions of said electrodes, a high frequency generator, which can be operatively associated with said device, wherein said generator can deliver non-simultaneously a high frequency signal output to each of said electrodes, and a feedback control circuit, which can be configured to regulate the signal output delivery to each of said electrodes so it can maintain a user settable temperature at tip portion of said electrodes when the electrodes can be in contact with the patient's body.

  • Patent number: 6451015
    Abstract: A high frequency generator system with a computer graphic two-dimensional user-interactable interface is achieved to allow selection of menus associated with the function, state, and output parameters of the high frequency generator system. A two-dimensional graphics display is coupled directly or remotely to a high frequency power source system which is further connected to electrodes in contact or proximity to the tissue of a patient's body. A two-dimensional display allows the user to see, in a compact, convenient, and comprehensive way, selection menus for use of the high frequency generator system, control of its parameters, monitoring of its processes during clinical application, and graphics displays related to historic or current image scan data and real-time monitoring of output parameters related to the application. Pre-set or user-selectable arrays of parameters can be selected through the two-dimensional user interface to the high frequency generator system.
