Abstract: An electrosurgical system includes an RF current generator, a handle body, and an end effector in mechanical communication with the handle body. The end effector has a first jaw including a first electrode having a first electrode surface in electrical communication with a first terminal of the generator. The end effector also includes a second jaw including a second electrode having an essentially planar second electrode surface in electrical communication with a second terminal of the generator The first jaw includes at least one feature configured to apply an amount of a compressive force to a tissue compressed between the at least one feature and the second electrode surface that differs from an amount of a compressive force applied to the tissue compressed between the first electrode surface and the second electrode surface when the first jaw is placed in a proximate position to the second jaw.

Abstract: An end effector of an electrosurgical device may include a discharge port, an aspiration port, two electrodes, and a diverter formed from a porous material. The diverter includes a matrix having voids to receive fluid from the discharge port. A releasable diverter assembly may include an assembly body configured to receive a pair of electrodes and a diverter composed of a porous material. A shaft assembly of an electrosurgical device may include two electrodes and two fluid cannulae. Each cannula may be disposed proximate to a surface of each of the electrodes. An end effector of an electrosurgical device may include a fluid discharge port, two electrodes, and a diverter disposed therebetween. A proximal edge of the diverter may form a secant line with respect to the end of the discharge port so that fluid emitted by the discharge port is disposed on a surface of the diverter.

Abstract: A variety of methods for managing a re-usable ultrasonic medical device may include a medical device control module capable of receiving functional data from a user assembled or reassembled ultrasonic medical device, and notifying the user if a value of the functional data lies within an acceptance range. If the value of the functional data does not lie within the acceptance range, the control module may prompt a user to reassemble the device or to clean or replace one or more components thereof. The functional data may relate to a clamp force of a jaw assembly, an impedance or resonant frequency value of an ultrasonic blade, or a mechanical displacement value of one or more moving components of the device.
