  • Patent number: 11478297
    Abstract: Systems and methods for controlling energy delivered to an area of tissue during a treatment procedure are provided. The system includes a device for delivering energy to the area of tissue; an energy generator for generating and supplying energy to the device; and a controller for controlling an amount of energy generated by the energy generator and delivered to the area of tissue by the device. Controlling the amount of energy delivered to the area of tissue alters a primary zone of the area of tissue to a first level, alters a secondary zone to a second level, alters a tertiary zone to a third level, or a combination thereof, where the first level, the second level, the third level, or a combination thereof is predetermined, and where a coverage area of the primary zone, the secondary zone, the tertiary zone, or a combination thereof is also predetermined.

  • Publication number: 20210169556
    Abstract: A method of treating tissue of a patient's body includes providing a power source coupled to at least one probe assembly. The probe assembly includes an elongate member with a distal region and a proximal region. The distal region has an electrically and thermally-conductive energy delivery device for delivering one of electrical and radiofrequency energy to the patient's body. The electrically and thermally-conductive energy delivery device has one or more internal lumens for circulating a cooling fluid therethrough and an electrically and thermally-conductive protrusion having a temperature sensing element. The temperature sensing element extends from a distal end of the energy delivery device. The method includes inserting the energy delivery device of the at least one probe assembly into the patient's body. Further, the method includes routing the energy delivery device of the at least one probe assembly to the tissue of the patient's body.

  • Publication number: 20210169555
    Abstract: A method for preparing a cooled radiofrequency probe for use to treat tissue of a patient's body includes providing a plurality of cooled radiofrequency probes. Each of the plurality of cooled radiofrequency probes includes an elongate member with a distal region and a proximal region. The distal regions each have an electrically and thermally-conductive energy delivery device for delivering one of electrical and radiofrequency energy to the patient's body. The electrically and thermally-conductive energy delivery devices each have one or more internal lumens for circulating a cooling fluid therethrough and an electrically and thermally-conductive protrusion having a temperature sensing element. The temperature sensing elements of each protrusion extends from a distal end of the energy delivery device. Further, each of the temperature sensing elements has a different length that extends from the distal end of the energy delivery device.

  • Publication number: 20200188054
    Abstract: The present invention is directed to a system for delivering radiofrequency ablation energy to an area or volume of tissue. The system includes a wrap, where a stiffening element surrounds an opening in the wrap, where the stiffening element transfers radial compression to the area or volume of tissue, where the radial compression increases stability of the area or volume of tissue; and at least one radiofrequency ablation probe having an active electrode, where the at least one radiofrequency ablation probe is connected to a radiofrequency generator via a lead. A device that includes a wrap and a method of delivering radiofrequency ablation energy to a volume of tissue via the device are also described.

    Abstract: Systems and methods for controlling energy delivered to an area of tissue during a treatment procedure are provided. The system includes a device for delivering energy to the area of tissue; an energy generator for generating and supplying energy to the device; and a controller for controlling an amount of energy generated by the energy generator and delivered to the area of tissue by the device. Controlling the amount of energy delivered to the area of tissue alters a primary zone of the area of tissue to a first level, alters a secondary zone to a second level, alters a tertiary zone to a third level, or a combination thereof, where the first level, the second level, the third level, or a combination thereof is predetermined, and where a coverage area of the primary zone, the secondary zone, the tertiary zone, or a combination thereof is also predetermined.
