Abstract

The invention relates to an ostomy device having a body side surface and an opposing backing surface. The body side surface has a layer of adhesive capable of being manually shaped to conform to the shape of the stoma.

Claims

1. An ostomy device having a body side surface and an opposing backing surface wherein said body side surface includes a layer of adhesive, said adhesive being capable of being manually shaped to conform to the shape of a stoma, said adhesive being adhereable to said backing surface with a bond strength sufficient to limit recovery of the adhesive to less than 0.125 inches.

2. The ostomy device of claim 1, wherein said opposing backing surface has a surface that is not a pressure sensitive adhesive.

3. The ostomy device of claim 1, wherein said adhesive is a pressure sensitive silicone adhesive.

4. The ostomy device of claim 3, wherein said pressure sensitive silicone adhesive is a hot melt silicone adhesive.

5. The ostomy device of claim 1, wherein said opposing backing surface has sufficient compliance so as to allow reshapeability.

6. The ostomy device of claim 1, wherein said opposing backing surface is composed of a material selected from the group consisting of materials from natural or synthetic origin including cellulose, alginates, chitosan and its derivatives, elastomers, polyesters, polyacrylonitriles, polyolefins, diene elastomers, polyamides, polyurethanes, polyethers, polyvinyl alcohol, polyether block amides, polyimides, rayon, rubber, silicones, thermoplastic polymers and elastomers, polyacrylates, polymethacrylates, ionomers, polyvinylacetate and its copolymers, polyvinylchloride, polyvinylidene chloride, fluorinated polymers, and combinations thereof.

7. The ostomy device of claim 1, wherein said opposing backing surface has a form selected from the group consisting of film, open or closed cell foam, a non-adhesive coating, woven fabric, non-woven fabric, fibers, meshes, screens, wicking structures, perforated structures, porous structures, planar or non-planar sheets, planar or non-planar structures, and combinations thereof.

8. The ostomy device of claim 1, wherein the adhesive is a layered structure.

9. The ostomy device of claim 1, wherein the backing is a layered structure.

10. The ostomy device of claim 1 further comprising a release liner to protect the adhesive surface prior to use.

11. The ostomy device of claim 9, wherein the device is a non-planar structure including concave or convex shaped structures.

12. The ostomy device of claim 9, wherein the device is substantially a planar structure.

13. The ostomy device of claim 3, wherein said pressure sensitive silicone adhesive is a solvent based adhesive.

14. The ostomy device of claim 3, wherein said pressure sensitive silicone adhesive is a silicone gel adhesive.

15. the ostomy device of claim 3, wherein said pressure sensitive silicone adhesive is curable silicone adhesive.
