Abstract: An end effector assembly of a surgical instrument includes opposing first and second jaw members. A first sealing plate is positioned on the first jaw member. The first sealing plate defines a first surface facing the second jaw member. A second sealing plate is positioned on the second jaw member. The second sealing plate defines a second surface facing the first jaw member. A mesa is formed in the first sealing plate. The mesa protrudes from the first surface toward the second surface in the second position of the first and second jaw members. A material is disposed on the mesa. The mesa and the material define a stop member. The stop member maintains a gap distance between the first and second surfaces when the first and second jaw members are in the second position.
