Patent ID: 8292888

Claim:
An electro-mechanical surgical device, comprising: a first jaw; a second jaw opposing the first jaw, the first jaw and the second jaw configured to clamp tissue therebetween; a plurality of electrodes arranged on the first jaw and the second jaw, the plurality of electrodes including a first electrode comprising at least one tissue-penetrating electrode arranged on one of the first jaw and the second jaw, and at least one second electrode arranged on another of the first jaw and the second jaw so as to remain in opposed correspondence with the first electrode when the first jaw and the second jaw are in an open position and a clamped position; at least one ampulla positioned on at least one of the first jaw and the second jaw, the at least one ampulla configured to release material contained within the at least one ampulla upon being pierced by the at least one tissue-penetrating electrode to coagulate tissue and induce hemostasis of the tissue with the material upon activating the released material with the at least one tissue-penetrating electrode of the plurality of electrodes; and an arrangement configured to supply electrical energy to the electrodes so that the first electrode has a polarity opposite a polarity of the at least one second electrode.
