Abstract: An electro-mechanical surgical device, system and/or method may include a housing, at least two opposing jaw, and at least one electrical contact associated with at least one of the jaws. The electrical contact may include at least one of a bipolar electrical contact and an ultrasonic electrical contact. The electrical contact may be a row of electrodes located on one or all of the jaws. A sensor may also be associated with any tissue located between the jaws to sense and report the temperature of that tissue. A piercable ampulla containing fluid may also be placed on at least one of the jaws so that the fluid is releasable when the jaws are in closed position and the electrode(s) pass through the tissue into the piercable ampulla.
