Abstract: A wound dressing comprising: a backing sheet; a layer of pressure-sensitive adhesive on the backing sheet; an island of absorbent material having smaller area than the backing sheet and applied onto a central region of the backing sheet so as to leave a margin of adhesive-coated backing sheet around the absorbent material, and an apertured wound facing layer applied over the absorbent material and adhered to the backing sheet around said island by said pressure-sensitive adhesive, wherein the apertured wound facing layer comprises an apertured substrate having a coating of a silicone gel on the wound facing surface thereof, the open area of the apertured wound facing layer is from about 5% to about 75%, and the apertured wound facing layer comprises apertures having an open area of from about 2 mm2 to about 100 mm2.

Abstract: A silver-containing tissue dressing for providing antimicrobial properties to a wound site is disclosed. In some embodiments, the tissue dressing may include a wound contact layer having a substrate material coated with a tacky hydrophobic silicone material, and silver-containing particles dispersed in the silicone material. The different surfaces of the substrate material may be coated with the silicone material having various amounts of tackiness. The silver material may provide antimicrobial properties when the tissue dressing is placed in contact with the wound site.

Abstract: A method of applying a patterned coating of a silicone adhesive to a substrate sheet, comprising the steps of pattern coating a silicone precursor composition onto the substrate, followed by thermally curing the precursor composition coated on the substrate. The precursor composition is a viscous fluid, and the pattern coating is performed by suitably modified block printing, intaglio printing or screen printing methods. Also provided are coated substrates obtainable by the methods of the invention, and wound dressings comprising such coated substrates.

Abstract: A wound dressing product that includes a substrate layer having an upper surface and a lower surface; a tacky silicone coating composition present on the upper surface and on the lower surface; and upper and lower release sheets covering the substrate and the tacky silicone coating composition on the upper and lower surfaces, respectively, and adhered to the surfaces by the tacky silicone coating composition, wherein the upper surface is less tacky than the lower surface whereby the upper release sheet can be removed from the upper surface more readily than the lower release sheet can be removed from the lower surface. Also provided are methods for making such dressings.
