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: A circular stapler is disclosed. The circular stapler includes a handle assembly, an elongate body, a cartridge assembly, a trocar, and a light source. The elongate body extends from the handle assembly and defines a longitudinal axis. The cartridge assembly is disposed adjacent a distal end of the elongate body and includes a pusher assembly. The pusher assembly is movable to cause staples to be ejected from the cartridge assembly. The trocar is disposed in mechanical cooperation with the cartridge assembly and is longitudinally advanceable to puncture tissue. The light source is disposed in mechanical cooperation with the trocar, and is configured to project a light beam distally of the trocar.

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 method of treating bowel diseases includes introducing a fluid into a portion of a patient's colon and applying energy thereto from an external energy source such that the fluid and the energy cooperate to treat tissue of the portion of the patient's colon in contact with the fluid. Another method of treating inflammatory bowel diseases includes sealing a portion of a patient's colon, introducing an electrically-conductive fluid thereto, and energizing an electrode disposed therein to treat tissue of the portion of the patient's colon in contact with the electrically-conductive fluid. Another method of treating inflammatory bowel diseases includes sealing a portion of a patient's colon and introducing a heated fluid at a temperature equal to or above 60° C. to treat tissue of the portion of the patient's colon in contact with the heated fluid.

Abstract: An ultrasonic surgical instrument is provided. The ultrasonic surgical instrument includes a housing having an elongated shaft extending therefrom. A first jaw member disposed at a distal end of the shaft is movable between open and clamping configurations. A pair of second jaw members disposed at the distal end of the shaft are movable between open and clamping configurations. A cutting blade extending to the distal end of the shaft is operably coupled to the housing. The pair of second jaw members and first jaw member are moveable to the clamping configuration to compress tissue of interest for removing moisture therefrom prior to the tissue of interest being treated.

Abstract: An ultrasonic surgical instrument is provided. The ultrasonic surgical instrument includes a housing having an elongated shaft extending therefrom. The shaft has a jaw member disposed at a distal end thereof. The jaw member is movable between an open configuration and a clamping configuration and includes a tissue contacting surface thereon. A cutting blade extends from a distal end of the shaft and operably couples to the housing and adjacent the jaw member to treat tissue. A selectively removable laminate liner is positionable over the tissue contacting surface of the jaw member and configured to prevent contact between the tissue contacting surface and the cutting blade when the cutting blade is treating tissue.

Abstract: An electrosurgical generator is disclosed. The generator includes a radio frequency output stage configured to generate a radio frequency waveform and a sensor circuit configured to measure a property of the radio frequency waveform during a predetermined sampling period to determine whether an arc event has occurred. The generator also includes a controller configured to determine a total charge and/or total energy deposited by the radio frequency waveform during the predetermined sampling period associated with the arc event. The controller is further configured to adjust the output of the electrosurgical generator based on at least one parameter to limit arcing.
