Abstract

An adjustable wound closure device includes at least one band or strip retaining element provided for attachment in the region of at least one edge of a wound. The retaining element has a multiplicity of hook elements on at least part of at least one of its two faces. The wound closure device further includes at least one gauze cover element which substantially completely covers the wound and the edge regions provided with the retaining element. The hook-like elements of the retaining element and the meshes of the cover element are designed and arranged such that the wound can be reversibly closed by a positive engagement of at least some of the hook-like elements in the meshes.

Claims

1. An adjustable wound closure device comprising:

at least one band or strip retaining element that attaches in a region of at least one edge of a wound, wherein the retaining element has a multiplicity of hook elements on at least part of at least one of its two faces; and

at least one gauze cover element that substantially completely covers the wound and the edge regions provided with the retaining element,

wherein the hook elements of the retaining element and the meshes of the cover element arranged such that the wound can be reversibly closed by a positive engagement of at least some of the hook elements in the meshes.

2. The wound closure device as claimed in claim 1, further comprising an additional film arranged over the wound closure device after the wound has been closed, and the film is optionally provided with adhesives in edge regions optionally protruding beyond the wound closure device.

3. The wound closure device as claimed in claim 2, wherein the film is permeable to water vapor.

4. The wound closure device as claimed in claim 2, wherein the film is a plastic film comprising polyurethane.

5. The wound closure device as claimed in claim 1, wherein the retaining element comprises a biocompatible plastic.

6. The wound closure device as claimed in claim 1, wherein the retaining element on a face directed away from the hook-like elements has adhesive to apply the retaining element to the wound edge.

7. The wound closure device as claimed in claim 1, wherein the retaining element has a width of less than 20 mm.

8. The wound closure device as claimed in claim 1, wherein the retaining element, including the hook elements, has a height of 0.5 mm to 5 mm.

9. The wound closure device as claimed in claim 1, wherein the hook elements of the retaining element are in the shape of a mushroom head.

10. The wound closure device as claimed in claim 1, wherein the hook elements of the retaining element have harpoon-shaped barbs.

11. The wound closure device as claimed in claim 1, wherein the gauze cover element is a woven tulle fabric.

12. The wound closure device as claimed in claim 1, wherein the gauze cover element comprises non-resorbable plastic threads.

13. The wound closure device as claimed in claim 1, wherein the gauze cover element has a weight of 10 to 100 g/m².

14. The wound closure device as claimed in claim 1, wherein the gauze cover element has an elongation at break of 30% to 100%.

15. The wound closure device as claimed in claim 1, wherein, on at least one of the edges of the gauze cover element, at least one planar means, or a means formed from individual threads or a plurality of threads, is provided for orienting the cover element with respect to the wound and to the retaining element.

16. The wound closure device as claimed in claim 1, wherein the gauze cover element, on at least one of its two faces, is provided at least partially with a coating or film.

17. The wound closure device as claimed in claim 16, wherein the coating or film is permeable to water vapor.

18. The wound closure device as claimed in claim 16, wherein the coating or film comprises a coating or film of polyurethane.

19. The wound closure device as claimed in claim 1, wherein the mesh width of the gauze cover element is at least twice as great as the diameter of the hook-like elements of the retaining element.

20. The wound closure device as claimed in claim 19, wherein the mesh width of the gauze cover element is two to four times as great as the diameter of the hook elements of the retaining element.

21. The wound closure device as claimed in claim 1, wherein an arrangement of the hook elements on the retaining element is chosen such that between 1 and 3 hook elements fit into one mesh of the gauze cover element.

22. The wound closure device as claimed in claim 21, wherein, relative to the arrangement of the retaining element on the wound edge, different numbers of hook elements of the retaining element fit into one mesh in a direction of the wound profile and in a direction of wound tensioning to be applied to the wound of the gauze cover element, with one hook element fitting into one mesh in a horizontal direction and two hook elements fitting into one mesh in a vertical direction.

23. The wound closure device as claimed in claim 1, wherein the holding strength of the wound closure device on the wound, upon tensile loading of the gauze cover element perpendicular to the wound profile, is at least 10 N.

24. The wound closure device as claimed in claim 1, wherein the retaining element on at least one of its two longitudinally extending edges has a liquid retainer and/or liquid repellent that can reduce or prevent movement of wound liquid of the wound into the hook structure of the retaining element.

25. The wound closure device as claimed in claim 24, wherein the liquid retainer/repellent is a layer or a coating in the form of an edge bead.

26. The wound closure device as claimed in claim 25, wherein the layer or coating comprises polyurethane or polyethylene.

27. The wound closure device as claimed in claim 24, wherein the retainer/repellent is a foam.

28. The wound closure device as claimed in claim 1, wherein the wound closure device is in a sterile form arranged in a sterile package.

29. A kit for closing wounds comprising at least one wound closure device as claimed in claim 1 in sterilized form in a sterile package.

30. (canceled)

31. A method for closing wounds, wherein at least one band or strip retaining element, which has a multiplicity of hook-like elements on at least part of at least one of its two faces, is applied in a region of at least one edge of a wound, and at least one gauze cover element, that substantially completely covers the wound and the edge regions provided with the retaining element is arranged over the wound and the retaining element such that wound closure takes place through positive engagement of hook elements of the retaining element in meshes of the cover element.
