HYBRID DRAPE HAVING A GEL-COATED PERFORATED MESH
A system for treating a tissue site with negative-pressure is described. The system includes a manifold configured to be positioned adjacent to the tissue site and a drape configured to be positioned over the tissue site and the manifold to form a sealed space. The system also includes a negative-pressure source configured to provide negative-pressure to the sealed space. The drape includes a film layer, a layer of a bonding adhesive coupled to the film layer, and a mesh coupled to the layer of the bonding adhesive. The mesh includes a coating of a sealing adhesive and one or more bonding apertures. Methods of manufacturing the drape are also described.

35 . A method for manufacturing a drape for a negative-pressure system, the method comprising:
providing a film layer;
coupling a layer of a bonding adhesive to the film layer;
forming a mesh;
coating the mesh with a sealing adhesive;
forming one or more bonding apertures in the mesh; and
coupling the mesh to the layer of the bonding adhesive.
36 . The method of claim 35 , wherein the bonding apertures are formed in the mesh before coating the mesh.
37 . The method of claim 35 , wherein forming the mesh comprises weaving a plurality of fibers to form the mesh.
38 . The method of claim 35 , wherein forming the mesh comprises knitting a plurality of fibers to form the mesh.
39 . The method of claim 35 , wherein forming the mesh comprises extruding a plurality of fibers to form the mesh.
40 . The method of claim 39 , wherein extruding the plurality of fibers to form the mesh further comprises extruding the fibers so that the fibers intersect with a prominence less than about 1 millimeter.
41 . The method of claim 35 , wherein the mesh comprises a plurality of fibers and a diameter of each fiber is less than about 1 millimeter.
42 . The method of claim 35 , wherein the mesh comprises a plurality of fibers and each fiber comprises a monofilament.
43 . The method of claim 35 , wherein the mesh comprises a plurality of fibers and each fiber comprises a plurality of twisted monofilaments.
44 . The method of claim 35 , wherein the mesh comprises a plurality of fibers and each fiber comprises a staple fiber.
45 . The method of claim 35 , wherein forming the mesh comprises forming the mesh from a plurality of fibers having intersections and compressing the mesh to reduce a prominence at each intersection of the fibers.
46 . The method of claim 35 , wherein forming the mesh comprises forming the mesh from a plurality of fibers having intersections and calendaring the mesh to reduce a prominence at each intersection of the fibers.
47 . The method of claim 35 , wherein forming the mesh comprises forming the mesh to have a plurality of mesh apertures each having an effective diameter between about 0.5 millimeters and about 4 millimeters.
48 . The method of claim 35 , wherein coating the mesh comprises applying a coating weight of the sealing adhesive between about 100 grams per square meter and about 500 grams per square meter.
49 . The method of claim 35 , wherein forming the bonding apertures in the mesh comprises forming each bonding aperture with an effective diameter between about 5 millimeters and about 15 millimeters.
