Abstract
A surgical instrument includes a handle portion, a shaft housing a firing bar, an end effector comprising an anvil, a lower jaw, and a stapling and severing assembly responsive to a longitudinal closing motion produced by the handle portion and the shaft. The lower jaw is configured to receive a cartridge when in an open position. The cartridge includes a housing, a plurality of staples disposed in the housing, and a deck disposed over the plurality of staples. The deck defines apertures, with each aperture being substantially disposed over each staple. The cartridge further receives a matrix including glue beads suspended in the matrix. The staples are driven through the matrix to secure the matrix to tissue. The glue beads are activated when the matrix is secured to the tissue, such that the activated adhesive further secures the staple line in the tissue.
