    • The invention provides dry electrographic toner compositions comprising toner particles. The toner particles comprise polymeric binder comprising at least one amphipathic copolymer comprising one or more S material portions and one or more D material portions prepared from an organosol reaction process utilizing a liquid carrier reaction medium having a Kauri-Butanol number less than about 30 mL. The S material portion comprises at least one soluble component and at least one non-sorptive component, wherein the non-sorptive component is the reaction product of monomers having an absolute difference in Hildebrand solubility parameter from the liquid carrier of about 3.0 MPa1/2 or greater. Additionally, dry electrographic toner compositions are provided wherein the toner particles comprise polymeric binder comprising at least one amphipathic copolymer comprising one or more S material portions and one or more D material portions. The S material portion of the amphipathic copolymer has an average Hildebrand solubility parameter of from about from about 16 MPa1/2 to about 17.3 MPa1/2, and comprises at least one non-sorptive component having an average Hildebrand solubility parameter that is at least about 0.4 MPa1/2 greater than the average Hildebrand solubility parameter of the S material portion.The resulting dry toner composition can exhibit excellent final image durability characteristics, and can also provide excellent images at low fusion temperatures on a final image receptor.

    • An electrosurgical medical device and method for creating thermal welds in engaged tissue. In one embodiment, at least one jaw of the instrument defines a tissue engagement plane carrying a variable resistive body of a positive temperature coefficient material that has a selected decreased electrical conductance at each selected increased temperature thereof over a targeted treatment range. The variable resistive body can be engineered to bracket a targeted thermal treatment range, for example about 60° C. to 80° C., at which tissue welding can be accomplished. In one mode of operation, the engagement plane will automatically modulate and spatially localize ohmic heating within the engaged tissue from Rf energy application across micron-scale portions of the engagement surface. In another mode of operation, a variable resistive body will focus conductive heating in a selected portion of the engagement surface.
