1. A surgical stapling apparatus comprising:
- a handle assembly;
a tubular body portion extending from the handle assembly;
a staple cartridge assembly extending from the tubular body portion;
an anvil assembly coupled to the staple cartridge assembly and movable relative thereto between open and closed positions; and
a surgical buttress releasably attached to the staple cartridge assembly or the anvil assembly, the surgical buttress including first, second, and third porous film layers successively stacked on each other and interconnected at a plurality of attachment points that define a plurality of pockets between the first and second porous film layers and the second and third porous film layers, wherein the plurality of attachment points between the first and second porous film layers of the surgical buttress are different from the plurality of attachment points between the second and third porous film layers of the surgical buttress such that the plurality of attachment points form at least one of the plurality of pockets between the first and second porous film layers that is different in size from at least one of the plurality of pockets between the second and third porous film layers.
