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: Systems and methods of imaging include projecting infrared (IR) light from the endoscope toward the at least one anatomical feature (e.g., the exterior of a liver or lung), capturing the IR light, projecting optical light from the endoscope toward a similar portion of the anatomical feature, and capturing the optical light. Once the IR light and the optical light are captured, both are associated with one another to generate an intra-operative 3D image. This projection and capture of IR and optical light may occur at discrete times during the imaging process, or simultaneously.

Abstract: A method of modeling lungs of a patient includes acquiring computed tomography data of a patient's lungs, storing a software application within a memory associated with a computer, the computer having a processor configured to execute the software application, executing the software application to differentiate tissue located within the patient's lung using the acquired CT data, generate a 3-D model of the patient's lungs based on the acquired CT data and the differentiated tissue, apply a material property to each tissue of the differentiated tissue within the generated 3-D model, generate a mesh of the 3-D model of the patient's lungs, calculate a displacement of the patient's lungs in a collapsed state based on the material property applied to the differentiated tissue and the generated mesh of the generated 3-D model, and display a collapsed lung model of the patient's lungs based on the calculated displacement of the patient's lungs.

Abstract: An electrosurgical device is provided and includes a handset having a shaft extending therefrom. The electrosurgical device includes a pair of electrodes disposed at a distal end of the shaft. One or more sensors are in operable communication with the pair of electrodes to detect a pressure applied thereto. The amount of electrosurgical energy that is transmitted to the pair of electrodes is proportional to the amount of pressure that is applied to the pair of electrodes and detected by the sensor.

Abstract: A surgical stitching device is configured for single hand operation that enables passage of a suture needle through tissue with minimal operational requirement. The surgical needle is selectively securable to first and second jaws that are pivotably coupled to each other. When the first and second jaws are in an open configuration, in which, the first and second jaws are spaced apart, the suture needle is detachably secured to the first and second jaws. When the first and second jaws are in a closed configuration, in which, the first and second jaws are approximated, the suture needle is detachably secured to one of the first and second jaws and is detached from the other one of the first and second jaws. Such single hand operation facilitates procedures such as, e.g., extraterritorial loop suture closure.

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 surgical instrument includes a housing having a shaft affixed thereto, a reciprocatable drive rod slideably disposed at least partially within the shaft, and a force applicator coupled to the drive rod. The shaft includes first and second jaw members attached to a distal end thereof, at least one of which movable relative to the other from a first position wherein the jaw members are disposed in spaced relation relative to one another to at least a second position closer to one another wherein the jaw members cooperate to grasp tissue therebetween. The force applicator and the drive rod mechanically communicate to impart movement to at least one of the jaw members. The bipolar forceps includes a handle assembly and a force-balance interface. The force-balance interface configured to translate a multiple of the user-applied force exerted on the handle assembly into the jaw members.

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.
