1. An absorbable, permeability-modulated barrier composite comprising:

  • a. at least three physiocochemically distinct components;

    b. a first component comprising a flexible film comprising a synthetic absorbable polymer selected from the group consisting ofi. a polyaxial copolyester derived from at least two monomers selected from the group consisting of glycolide, lactide, ε

    -caprolactone, trimethylene carbonate, p-dioxanone, 1,5-dioxepan-2-one and a morpholinedione;

    ii. a polyether ester derived from a polyether-glycol that is grafted with at least one monomer selected from the group consisting of glycolide, lactide, ε

    -caprolactone, trimethylene carbonate, p-dioxanone, 1,5-dioxepan-2-one and a morpholinedione; and

    iii. a polyether-ester-urethane derived from a polyether-glycol that is grafted with at least one monomer selected from the group consisting of glycolide, lactide, ε

    -caprolactone, trimethylene carbonate, p-dioxanone, 1,5-dioxepan-2-one and a morpholinedione, to form a polyether ester glycol, where the polyether ester glycol is interconnected by urethane linkages formed through the reaction of said polyether ester glycol with an aliphatic diisocyanate;

    c. a second component comprising a knitted mesh; and

    d. a third component comprising an electrostatically spun, non-woven microfibrous fabric;

    wherein the flexible film is adjoined directly to the knitted mesh, and the knitted mesh is adjoined directly to the microfibrous fabric, to form a layered composite.
