Abstract: An electrosurgical system includes an electrosurgical instrument having an electrode with a polymeric dielectric coating; and an electrosurgical generator, which includes a power converter configured to generate RF energy; a sensor coupled to the power converter and configured to sense a parameter of the RF energy; and a controller coupled to the sensor and the power converter. The controller is configured to control the power converter to output an RF waveform to achieve conductor breakthrough through the polymeric dielectric coating. The controller is further configured to determine whether the conductor breakthrough occurred based on the parameter; and execute a treatment algorithm based on a determination of the conductor breakthrough.

Abstract: Jaw members of end effector assemblies include sealing plates configured to direct the amount and flow of energy through the sealing plates. The sealing plates may have a height varying from a minimal height to a maximum height along a width or a length of the sealing plate and/or a sealing surface including at least two impedance zones having different impedance values.

Abstract: Disclosed herein are compositions comprising recombinant arenavirus monoclonal antibodies and antigen-binding fragments thereof, as well as therapeutic methods using the antibodies. In some embodiments, the antibodies provide pan-arenavirus protection against a number of arenavirus types and strains.

Abstract: A stud retainer assembly includes a housing defining a stud chamber, and at least one stud-retaining arm disposed within the stud chamber. The at least one stud-retaining arm includes a stud engagement member comprising first and second teeth configured to engage a stud. The second tooth is recessed back with respect to the first tooth.

Abstract: A full-round head nail having an offset head is configured with a gusset formed integrally between an undersurface of the offset head and a superior portion of a shank. The head of the nail is relatively thin, and the shank is positioned radially off center of the round head such that no heel is formed at a point tangential to both the head and the shank. The gusset has a lofted surface tapering radially from a roundness at the zero heel to a taper at the toe. The gusset reinforces the junction of the shank with the head, supports the toe of the head, and distributes the force of a load on the head through a longitudinal axis of the shank, preventing the toe from bending or yielding and prevents the shank from yielding to the stresses of the load applied.

Abstract: A fastener driving tool including a power source having a reciprocating driver blade, a tool nose associated with the power source for receiving the driver blade for driving fasteners fed into the nose, a magazine constructed and arranged to house a supply of the fasteners and a magazine feeder mechanism associated with the magazine for sequentially feeding fasteners into the nose. The feeder mechanism operates between a retracted position and an advanced position. An electromechanical retention device is operationally associated with the feeder mechanism and is configured for retaining the feeder mechanism in the retracted position until the driver blade is positioned to allow fastener advancement into the nose.

Abstract: A hot melt adhesive or other thermoplastic material dispensing valve assembly comprises a pair of oppositely disposed electromagnetic solenoid assemblies which alternatively act upon a pair of armatures which are fixedly mounted upon a valve stem, upon which is fixedly mounted a valve member, so as to rapidly and assuredly control the reciprocal movements of the valve stem, and the valve member attached thereto, between its unseated or OPENED position and its seated or CLOSED position. A coil spring also biases the valve stem and the valve member toward the seated or CLOSED position such that when both of the electromagnetic solenoid assemblies are de-energized, the coil spring maintains the valve member at its seated or CLOSED position upon the valve seat.
