1. A method of forming a laminate of a surgical mesh having first and second surfaces, and an adhesive structure having adhesive and non-adhesive surfaces, comprising:

  • a) providing a first solvent-dissolvable mold including indentations;

    b) providing a first meltable polymer having a Young'"'"'s modulus of greater than 17 MPa to the first mold under conditions sufficient to permit filling the indentations of the first mold by the first polymer, said first polymer being non-dissolvable by the solvent;

    c) treating the first mold and first polymer of step b) to an extent sufficient to solidify the first polymer;

    d) laminating a surgical mesh, also non-dissolvable by said solvent, to an exposed surface of said first meltable polymer at the top of said first mold; and

    e) exposing the first mold, first polymer and surgical mesh to the solvent under mold-dissolving conditions to dissolve said first mold.
