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.

Claims (40)

1. A reduced pressure tissue treatment system comprising:

an applicator having an aperture;

a first pad section;

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

a fabric layer located at least partially between the second pad section and a drape, the fabric layer including a woven or non-woven fabric made from a fiber material;

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

a reduced pressure source in fluid communication with at least one of the first pad section and the fabric layer for providing reduced pressure to the aperture.

2. The reduced pressure tissue treatment system of claim 1 further comprising a canister fluidly connected between the reduced pressure source and the at least one of the first pad section and the fabric layer.

3. The reduced pressure tissue treatment system of claim 1 , wherein the fabric layer is located at least partially between the first pad section and the applicator.

4. The reduced pressure tissue treatment system of claim 1 further comprising an interface located between the reduced pressure source and the at least one of the first pad section and the fabric layer.

5. The reduced pressure tissue treatment system of claim 1 , 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.

6. The reduced pressure tissue treatment system of claim 1 , wherein the fabric layer is selected from the group consisting of polyamide, nylon, polyamide coated with polyurethane, polymeric meshes, non-woven melt blown polymers, and flexible sintered polymers.

7. The reduced pressure tissue treatment system of claim 1 , wherein the first pad section, the second pad section, and the fabric layer have a thickness of from about 5 mm to about 20 mm.

8. The reduced pressure tissue treatment system of claim 1 , wherein the fabric layer includes several overlapping layers joined together.

9. A reduced pressure tissue treatment system 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 fabric layer located at least partially between the first pad section and the applicator, the fabric layer further being located at least partially between the second pad section and the applicator;

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

a reduced pressure source in fluid communication with at least one of the first pad section and the fabric layer for providing reduced pressure to the aperture.

10. The reduced pressure tissue treatment system of claim 9 further comprising a canister fluidly connected between the reduced pressure source and the at least one of the first pad section and the fabric layer.

11. The reduced pressure tissue treatment system of claim 9 further comprising an interface located between the reduced pressure source and the at least one of the first pad section and the fabric layer.

12. The reduced pressure tissue treatment system for claim 9 , 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.

13. The reduced pressure tissue treatment system of claim 9 , 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.

14. The reduced pressure tissue treatment system of claim 9 , wherein the first pad section, the second pad section, and the fabric layer have a thickness from about 5 mm to about 20 mm.

15. The reduced pressure tissue treatment system of claim 9 , wherein the fabric layer includes several overlapping layers joined together.

16. A reduced pressure tissue treatment system 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 fabric layer located at least partially between the first pad section and a drape, the fabric layer further being located at least partially between the second pad section and the drape;

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

a reduced pressure source in fluid communication with at least one of the first pad section and the fabric layer for providing reduced pressure to the aperture.

17. The reduced pressure tissue treatment system of claim 16 further comprising a canister fluidly connected between the reduced pressure source and the at least one of the first pad section and the fabric layer.

18. The reduced pressure tissue treatment system of claim 16 further comprising an interface located between the reduced pressure source and the at least one of the first pad section and fabric layer.

19. The reduced pressure tissue treatment system of claim 16 , 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.

20. The reduced pressure tissue treatment system of claim 16 , 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.

21. The reduced pressure tissue treatment system of claim 16 , wherein the first pad section, the second pad section, and the fabric layer have a thickness of from about 5 mm to about 20 mm.

22. The reduced pressure tissue treatment system of claim 16 , wherein the fabric layer includes several overlapping layers joined together.
