1. A method of manufacturing a coated surgical mesh, said method comprising:
providing a surgical mesh comprising a first surface and a second surface, wherein the surgical mesh comprises a non-knitted/non-woven material;
providing a release sheet;
positioning an ingrowth-preventing coating onto the release sheet, wherein the ingrowth-preventing coating comprises a liquid dispersion of silicone;
allowing the ingrowth-preventing coating to settle on the release sheet under the influence of gravity so that the ingrowth-preventing coating has a substantially planar top surface;
placing the second surface of the surgical mesh onto the ingrowth-preventing coating;
applying pressure to the first surface of the surgical mesh so that the ingrowth-preventing coating is forced into the surgical mesh without penetrating all the way through the surgical mesh to the first surface of the surgical mesh;
curing the ingrowth-preventing coating so as to fuse the ingrowth-preventing coating to the surgical mesh, whereby to form the coated surgical mesh; and
removing the coated surgical mesh from the release sheet.
