  • Patent number: 12016615
    Abstract: An electrosurgical device is provided. The device includes a cooled probe, an introducer, and a side port for the introduction of liquid into a lumen defined by an outer diameter of the probe and an inner diameter of the introducer when the probe is positioned inside the introducer such that a distal end of the probe can contact a target site (e.g., the site near/adjacent the tissue to be treated). The side port can be connected to a syringe/other liquid introduction apparatus via tubing so that a liquid (e.g., a therapeutic agent, saline, etc.) can be injected into the lumen and can exit the distal region of the introducer so that it is delivered to the target site. Additionally, the syringe can be removed so that the tubing can serve as a vent during treatment with the electrosurgical device.
