The surgical stapling assembly comprises an end-effector extending from the distal end of the shaft. The end-effector comprises a first portion and a second portion. The first portion comprises a first face at least partially surrounding the aperture, a staple cavity defined in the first face, a staple removably positioned within the staple cavity, and a first electrode positioned one of on and proximate to the first face. The second portion comprises a second face, an anvil pocket defined in the second face, and a second electrode positioned one of on and proximate to the second face, and a second electrode. The first electrode and the second electrode each comprise an arcuate portion. The first electrode has a different polarity than the second electrode.
