Abstract

Devices, kits and methods described herein may be for wound healing, including the treatment, amelioration, or prevention of scars and/or keloids by applying and/or maintaining a pre-determined strain in an elastic skin treatment device that is then affixed to the skin surface using skin adhesives to transfer a generally planar force from the bandage to the skin surface. Applicators are used to apply and/or maintain the strains, and some of the applicators are further configured to provide at least some mechanical advantage to the user when exerting loads onto the skin treatment device.

Claims

1. A device for treating a skin surface, comprising:

a first device attachment member comprising a first plurality of outwardly oriented projections;

a second device attachment member comprising a second plurality of outwardly oriented projections; and

a resilient member configured to exert a separation force between the first and second device attachment members.

2. The device of claim 1, further comprising a releasable locking mechanism configured to maintain the resilient member in a retracted configuration.

3. The device of claim 2, wherein the retracted configuration is a strained configuration.

4. The device of claim 2, wherein the releasable locking mechanism comprises a releasable latch.

5. The device of claim 3, wherein the releasable locking mechanism is configured to lock at a pre-determined strain.

6. The device of claim 5, wherein the releasable locking mechanism is configured to resist further straining when locked at the pre-determined strain.

7. The device of claim 3, wherein the releasable locking mechanism is configured to lock at a plurality of pre-determined strains.

8. The device of claim 1, wherein the first device attachment member, the second device attachment member and the resilient member are integrally formed.

9. A wound dressing device, comprising an applicator configured to maintain an attached dressing in a strained configuration, comprising a first attachment region, a second attachment region, and an access region between the first and second attachment regions configured to provide access to an attached dressing when the dressing is in a strained configuration.

10. A wound dressing, comprising:

a silicone sheet structure comprising an upper surface, a lower surface, a first edge and a second edge opposite the first edge, the silicone sheet comprising;

a first adhesive region;

a second adhesive region spaced apart from the first adhesive region by a non-adhesive region;

a first flap region located between the first edge and the first adhesive region;

a second flap region located between the second edge and the second adhesive region;

a first applicator attachment site located between the first flap region and the first adhesive region; and

a second applicator attachment site located between the second flap region and the second adhesive region.

11. The wound dressing of claim 10, further comprising:

a first release liner releasably attached to the first adhesive region and the second adhesive region.

12. The wound dressing of claim 11, wherein the first flap region is an adhesive flap region.

13. The wound dressing of claim 12, further comprising a second release liner releasably attached to the first flap region.

14. The wound dressing of claim 13, wherein the second flap region is an adhesive flap region.

15. The wound dressing of claim 14, further comprising a third release liner releasably attached to the second flap region.

16. The wound dressing of claim 10, wherein the first and second adhesive regions comprise a pressure sensitive silicone adhesive with a release force of at least about 240 kg/m.

17. The wound dressing of claim 10, wherein the first and second adhesive regions comprise a pressure sensitive silicone adhesive with a release force of at least about 270 kg/m.

18. The wound dressing of claim 10, wherein the first and second adhesive regions comprise a pressure sensitive silicone adhesive with a release force of at least about 300 kg/m.

19. The wound dressing of claim 10, wherein the first and second adhesive regions comprise a pressure sensitive silicone adhesive with a release force of at least about 330 kg/m.

20. The dressing of claim 10, wherein the first applicator attachment site comprises a plurality of attachment openings.

21. The dressing of claim 11, wherein the first release liner has a lower surface and an upper surface with a different surface texture than the lower surface.

22. A dressing, comprising:

an elastic layer comprising an upper surface, a lower surface, a first edge, a second edge, a first applicator attachment site, a flap region between the first edge and the first applicator attachment site, a second applicator attachment site spaced away from the second edge; and

a first adhesive region located on the lower surface of the elastic layer.

23. A method for treating a wound, comprising:

straining an inner region of an elastic bandage between a first unstrained region and a second unstrained region, wherein each unstrained region is spaced away from two opposing edges of the bandage; and

attaching the strained inner region of the bandage to a skin site.

24. The method for treating a wound as in claim 23, wherein straining the inner region of the elastic bandage is performed before attaching the strained inner region of the bandage to the skin site.

25. The method for treating a wound as in claim 23, wherein attaching the strained inner region of the bandage to the skin site is performed without attaching the two opposing edges of the bandage to the skin site.

26. The method of claim 25, further comprising attaching the two opposing edges of the bandage to the skin site after attaching the inner region of the bandage to the skin site.

27. The method for treating a wound as in claim 23, further comprising reducing peak strain in the attached bandage while increasing peak strain at the skin site.

28. The method for treating a wound as in claim 23, further comprising attaching the two opposing edges of the bandage to the skin site.

29. The method for treating a wound as in claim 28, further comprising straining the unstrained regions of the bandage before attaching the two opposing edges of the bandage to the skin site.

30. The method for treating a wound as in claim 23, wherein straining the inner region of the unattached elastic bandage comprises stretching the inner region of the unattached elastic bandage to a pre-determined strain.
