摘要： A system for delivering energy to a patient's body includes a plurality of probes, a touch-sensitive display screen, and a controller communicatively coupled to each of the probes and the display screen. The controller is configured to perform operations including displaying a plurality of dynamically sized channel control regions within a user interface of the touch-sensitive display screen. Each of the plurality of channel control regions corresponds with at least one of the plurality of probes and is sized based at least in part on a number of the plurality of probes. The operations can include detecting a user touch action directed to a user-selected channel control region of the plurality of dynamically sized channel control regions. The operations can include performing a control action associated with the probe(s) that correspond with the user-selected channel control region when the user touch action is detected.

摘要： A system for delivering energy to a patient's body is disclosed that includes a plurality of probes, a touch-sensitive display screen, and a controller communicatively coupled to each of the probes and the display screen. The controller is configured to perform operations including displaying a virtual control object in the user interface of the touch-sensitive display screen that is associated with an operating parameter of a treatment procedure performed with the probe. The controller is configured to adjust the operating parameter when a user touch action is directed to the virtual control object. The controller is configured to convert the virtual control object into a non-control label based, at least in part, on a current status of the treatment procedure. The controller is configured to prohibit adjustment of the operating parameter using the non-control label in response to a user touch action that is directed to the non-control label.

摘要： A dispersive return pad for a radiofrequency ablation procedure includes a skin material adapted to be worn on a patient's skin, a conductive material positioned adjacent to the skin material, a non-conductive material surrounding the conductive material, and a phase-change material surrounding at least a portion of a side edge of the conductive material. Further, the phase-change material is configured to undergo a phase transition at a target temperature range corresponding to a non-damaging hyperthermic temperature range for the patient's skin. As such, the phase-change material is configured to absorb excess heating from the RF ablation procedure and to prevent burns to the patient's skin.

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. The method further includes determining at least one of a desired lesion size or a desired rate of power delivery required to treat the tissue. As such, the method includes selecting one of the probes from the plurality of cooled radiofrequency probes based on the length of the temperature sensing element thereof that achieves the desired lesion size or the desired rate of power delivery.

摘要： 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. The method also includes simultaneously circulating the cooling fluid through the one or more internal lumens via at least one pump assembly and delivering energy from the power source to the tissue through the energy delivery device. Further, the method includes monitoring one or more procedure parameters while delivering the energy from the power source to the tissue through the energy delivery device. Moreover, the method includes determining, in real-time, whether a rising impedance event is likely to occur in a predetermined time period based on the one or more procedure parameters and determining a command for the pump assembly based on whether the rising impedance event is likely to occur in the predetermined time period.
