    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: A surgical system includes an endoscope, a computing device, a vacuum source, and a laser source. The endoscope defines an elongate body having an ultrasound sensor disposed on a distal portion thereof, a first channel defined through the elongate body defining a first aperture extending through the distal portion, a second channel defined through the elongate body defining a second aperture extending through the distal portion and having an optical waveguide disposed therein. The computing device includes a display screen and a processor having a memory storing a software application, which when executed, processes image data captured by the ultrasound sensor and displays a representation of the patient's anatomy on the display screen. The vacuum source is in fluid communication with the first channel to cause a stone to be retained against the distal portion of the endoscope. The laser source is in electromagnetic communication with the optical waveguide.

    Abstract: A sphincter assist device includes a plurality of interconnected and adjacent links which define a ring. Each link includes a body section and a latch cam. The body section includes a first set of side beams and a first set of snap arms. The latch cam includes a post extending from the body section and a cam disposed at an end portion of the post. The cam is engagable with the first set of snap arms of an adjacent link. Translation of the cam displaces the first set of snap arms and the first set of side beams to transition the sphincter assist device between open and closed configurations. The first set of snap arms, in combination with the first set of side beams, exert a positive non-linear force profile on the cam, thus defining a non-linear force profile of the sphincter assist device between the open and closed configurations.

    Abstract: A desiccation device for operation on a target tissue includes a handle, a shaft extending distally from the handle, and a head. The shaft defines a lumen therethrough, and the head has a loop configuration supported on a distal end of the shaft. The head is hollow and defines a lumen therethrough. The lumen of the head is in fluid communication with the lumen of the shaft. At least a portion of the head is electrically connected to a source of electrosurgical energy. A fluid is circulatable through the lumens of the shaft and the head.

    Abstract: A system for controlling temperature of a fluid used during treatment of biological tissue includes a fluid temperature control apparatus. The apparatus includes at least one heat transfer device and a solution bag and/or a heat transfer membrane. The solution bag and/or the heat transfer membrane reside in thermal communication with the heat transfer device. When the solution bag and/or the heat transfer membrane is fluidically coupled to an electrosurgical device, fluid is supplied to the electrosurgical device at a controlled temperature during a surgical procedure utilizing the electrosurgical device to enable more efficient treatment of the biological tissue. A corresponding method includes fluidically coupling the fluid temperature control apparatus to the electrosurgical device and supplying fluid at a controlled temperature during a surgical procedure utilizing the electrosurgical device to enable more efficient treatment of the biological tissue.

    Abstract: An electrosurgical suction coagulator is disclosed having improved thermal insulation between the active electrode and adjacent tissue. In embodiments, passive insulation is used to control the transfer of thermal energy from an electrosurgical electrode into surrounding tissue. Braided, closed-sell foam material, and open cell foam materials may be used to thermally insulate the outer surface of a suction coagulator shaft from an inner electrode. In embodiments, a suction coagulator shaft includes an external covering formed from open-cell foam material, which may be saturated with a coolant, such as water or saline, to increase the thermal mass of the shaft. In other embodiments, active cooling delivers coolant to the operative site. In yet other embodiments, a suction coagulator shaft includes a cooling jacket through which coolant is passed to actively cool the instrument. The improved electrosurgical suction coagulator disclosed herein may have a reduced operating surface temperatures which may result in reduced risk of undesirable effects to adjacent tissue, and may result in reduced operative times and improved patient outcomes.
