Claim:
1. A surgical implant, comprising: a first porous film layer including a plurality of pores, and having a first degree of porosity and a first modulus of elasticity; a second porous film layer including a plurality of pores, and having a second degree of porosity that is different from the first degree of porosity and a second modulus of elasticity; and a third porous film layer including a plurality of pores, and having a third modulus of elasticity that is greater than the first and second moduli of elasticity of the first and second porous film layers to reinforce the surgical implant, the first, second, and third porous film layers being in a stacked configuration with the third porous film layer interposed between the first and second porous film layers, the first, second, and third porous film layers bonded to one another at a plurality of attachment points to define a plurality of separate discrete pockets between the first and third porous film layers and the second and third porous film layers, wherein the attachment points form a boundary around each of the plurality of separate discrete pockets, and the plurality of separate discrete pockets have at least a portion of the plurality of pores of the first or second porous film layers disposed within the boundary.
