    Abstract: An electrosurgical device is provided that includes a handset having a shaft extending therefrom, a pair of active electrodes at a distal end of the shaft, and a movable, electrically floating electrode selectively positionable between the active electrodes. The floating electrode, when positioned to contact tissue between the active electrodes, modifies the electrosurgical current flows through tissue. The resultant modified current flows enables a surgeon to more effectively to control tissue desiccation by focusing electrosurgical energy toward targeted tissue and by reducing peripheral current flows. Embodiments are provided wherein the active electrodes include cooling provisions. Related electrosurgical systems and method of use are also provided.

    Abstract: Provided in accordance with the present disclosure are systems for identifying a position of target tissue relative to surgical tools using a structured light detector. An exemplary system includes antennas configured to interact with a marker placed proximate target tissue inside a patient's body, a structured light pattern source, a structured light detector, a display device, and a computing device configured to receive data from the antennas indicating interacting with the marker, determine a distance between the antennas and the marker, cause the structured light pattern source to project and detect a pattern onto the antennas. The instructions may further cause the computing device to determine, a pose of the antennas, determine, based on the determined distance between the antennas and the marker, and the determined pose of the antennas, a position of the marker relative to the antennas, and display the position of the marker relative to the antennas.

    Abstract: A resectoscope includes a fixed electrode adapted to connect to a first electrical potential, a movable electrode adapted to connect to a second electrical potential and biased transversely towards the fixed electrode, and a spacer coupled to the movable electrode. The movable electrode and the spacer are longitudinally movable relative to the fixed electrode between a first position, wherein the spacer is disposed between the fixed electrode and the movable electrode so as to maintain a spacing between the movable electrode and the fixed electrode against the bias of the movable electrode, and a second position, wherein the spacer is disposed distally of the fixed electrode, allowing the movable electrode to move transversely towards the fixed electrode under the bias of the movable electrode.

    Abstract: The present disclosure provides a plasma catheter including a tubular member; a conductive cylindrical member; a first electrode; and a second electrode. The tubular member defines a longitudinal lumen therethrough and has a proximal portion and a distal portion. The conductive cylindrical member is disposed at the distal portion of the tubular member. The first electrode is embedded in a first side of the tubular member and coupled to the conductive cylindrical member. The second electrode is embedded in a second side of the tubular member diametrically opposed to the first side. The second electrode is offset from the tubular member and aligned with a center axis defined by the conductive cylindrical member.

    Abstract: A method for treating a sinus cavity is provided. The method includes the steps of inserting a plasma applicator into a sinus cavity defined in a bone mass, positioning the plasma applicator adjacent a tissue formation, generating a selectively reactive plasma effluent at the plasma applicator and directing the selectively reactive plasma effluent at the tissue formation. The selective nature of the reactive plasma enables treatment of specific targets inside the sinus while minimizing the effect on other tissues. Such treatment includes, but not limited to, sterilization of bacterial colonies, vaporization of unwanted tissues or foreign masses, stimulation of tissues by enriching the content of reactive oxygen and nitrous oxide pathways, and combinations thereof.
