Abstract
A coated surgical mesh, the coated surgical mesh comprising: a surgical mesh, the surgical mesh comprising a first surface and a second surface; and a tissue ingrowth-preventing coating applied to the second surface of the surgical mesh; wherein the tissue ingrowth-preventing coating penetrates a controllable amount part way through the surgical mesh.
Claims28
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.

- providing a release sheet;
- positioning an ingrowth-preventing coating comprising a liquid dispersion of silicone onto the release sheet using an applicator;
- allowing the ingrowth-preventing coating to evaporate for a period of time;
- placing the second surface of the surgical mesh onto the ingrowth-preventing coating;
- using a flattening piece to slide the surgical mesh around the ingrowth-preventing coating without pushing down on the surgical mesh;
- 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;
- removing the coated surgical mesh from the release sheet;
- and
- trimming around the coated surgical mesh.
