Abstract

A reduced pressure tissue treatment system includes an applicator having an aperture, a first pad section, and a second pad section substantially covering the aperture and positioned substantially adjacent the first pad section. A fabric layer is located at least partially between the second pad section and the drape, and the fabric layer includes a woven or non-woven fabric made from a fiber material. A drape substantially covers the first pad section, the second pad section, the fabric layer, and the applicator. A reduced pressure source is in fluid communication with at least one of the first pad section and the fabric layer for providing reduced pressure to the aperture.

12. The breathable dressing of claim 1 , wherein the first pad section and the second pad section have a thickness from about 5 mm to about 20 mm.

13. The breathable dressing of claim 1 , wherein the fabric layer includes several overlapping layers joined together.

14. A breathable dressing for treating tissue comprising:

an applicator having an aperture;

a first pad section;

a second pad section substantially covering the aperture and positioned substantially adjacent to the first pad section;

a drape substantially covering the first pad section, the second pad section, and the applicator;

a fabric layer having a first portion located between the first pad section and the drape, and a second portion located between the second pad section and the drape; and

wherein the fabric layer is adapted to receive a reduced pressure to be provided to the aperture.

15. The breathable dressing of claim 14 , wherein the first pad section and the second pad section are one single pad.

16. The breathable dressing of claim 15 , wherein the single pad is formed from porous foam.

17. The breathable dressing of claim 15 , wherein the single pad is formed from multi-components.

18. The breathable dressing of claim 15 , wherein the single pad is multilayered.

19. The breathable dressing of claim 15 , wherein the applicator is formed from a flexible material having a sufficiently high moisture vapor transmission rate.

20. The breathable dressing of claim 15 , wherein the drape is formed from a flexible material having a sufficiently high moisture vapor transmission rate.

21. The breathable dressing of claim 15 , wherein the drape is sealed to the applicator to enclose the single pad and the fabric layer.

22. The breathable dressing of claim 14 , further comprising an interface located between the reduced pressure source and at least one of the first pad section and the fabric layer.

23. The breathable dressing of claim 14 , wherein the first pad section and the second pad section are selected from the group consisting of open-cell reticulated foam, sintered polymers, ethylene vinyl acetate, fluoropolymers, polyurethane, polyolefin, vinyl acetate, polyvinyl alcohol, and their copolymers.

24. The breathable dressing of claim 14 , wherein the fabric layer is selected from the group consisting of woven fabric, non-woven fabric, polyamide, nylon, polyamide coated with polyurethane, polymeric meshes, non-woven melt blown polymers, and flexible sintered polymers.

25. The breathable dressing of claim 14 , wherein the first pad section and the second pad section-have a thickness from about 5 mm to about 20 mm.

26. The breathable dressing of claim 14 , wherein the fabric layer includes several overlapping layers joined together.
