1. A flat mesh surgical implant comprisinga flat, biocompatible, polymeric mesh having first and second opposing sides, the mesh having an overall area, and having pores extending therethrough between the first and second opposing sides over more than 90% of the total area, wherein the pores range in size from 1.5 to 8 mm;

  • a first synthetic, resorbable polymer film positioned adjacent the first side of the mesh, said first film having anti-adhesion properties; and

    a second synthetic, resorbable polymer film positioned adjacent the second side of the mesh, said second film having anti-adhesion properties,wherein the first and second polymer films are bonded to one another at a plurality of points passing through the pores of the mesh such that the mesh is not bonded to the first or second polymer films and such that the mesh is contained in a cavity between the films, and wherein the resulting implant has no pores extending therethrough, the flat mesh, first film and second film forming a flat mesh surgical implant, such that when the implant is implanted into a patient the first and second resorbable polymer films prevent surgical adhesions for a sufficiently effective period of time prior to resorbing, and tissue is subsequently allowed to grow into the pores of the flat mesh.
