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 system for treating a patient, comprising:

a skin treatment device configured to be strained; and

a tensioning element comprising;

a structure configured to permit shaping, comprising;

a plurality of support portions; and

at least one moveable joint positioned between at least two of the plurality of support portions;

a first attachment portion configured to releasably couple the structure to a first portion of the skin treatment device; and

a second attachment portion configured to releasably couple the structure to a second portion of the skin treatment device;

wherein the at least one moveable joint is configured to permit movement of the tensioning element to strain the skin treatment device between the first attachment portion and second attachment portion.

2. The system of claim 1:

wherein the first attachment portion of the tensioning element is configured to attach to the first portion of the skin treatment device, and the second attachment portion of the tensioning element is configured to attach to the second portion of the skin treatment device;

wherein each of the first attachment portion and the second attachment portion of the tensioning element comprises a length and a configuration permitting flexion along the length; and

wherein the first attachment portion is configured to be moved with respect to the second attachment portion to create the strain in the skin treatment device.

3. The system of claim 2, wherein the first attachment portion and the second attachment portion comprise discrete elements.

4. The system of claim 3, wherein the discrete elements of the first attachment portion are attached by shapeable elements and wherein the discrete segments of the second attachment portion are attached by shapeable elements.

5. The system of claim 4, wherein the first attachment portion is configured to limit a range of flexion along its length and the second attachment portion is configured to limit a range of flexion along its length.

6. The system of claim 5, wherein each of the shapeable elements is

configured to permit bending and comprises:

a plurality of shaping portions; and

at least one shapeable joint positioned between at least two of the plurality of shaping portions and is configured to permit movement of each of the shapeable elements.

7. The system of claim 6, wherein at least one of the first attachment portion and second attachment portion comprises an attachment mechanism selected from a group consisting of a plurality of projections oriented away from the other first or second attachment portion, and a hook-and-loop attachment region.

8. The system of claim 6, wherein the first attachment portion and second attachment portion each comprise a plurality of projections oriented away from the other attachment portion.

9. The system of claim 6, wherein the first support portion and the second support portion are each configured to limit a range of movement of the tensioning element.

10. The system of claim 6, wherein at least one of the shapeable elements comprises a relatively flexible material.

11. The system of claim 6, wherein the at least one shapeable joint is bendable.

12. The system of claim 6, wherein the at least one shapeable joint comprises a hinge mechanism.

13. The system of claim 6, wherein the structure is configured to permit shaping further comprises a plurality of relatively rigid segments.

14. The system of claim 13, wherein the plurality of rigid segments are attached by moveable elements wherein the moveable elements permit a range of bending of the tensioning element and the plurality of rigid segments are configured to limit the range of bending of the tensioning element.

15. The system of claim 6, wherein the tensioning element further comprises a length and wherein the structure is configured to permit flexion along its length.

16. The system of claim 6, further configured to provide a variable curvature.

17. The system of claim 6, wherein the tensioning element is configured to be shaped to generally match a portion of a subject'"'"'s body profile.

18. The system of claim 6, wherein the tensioning element is configured to shape the skin treatment device when attached at the first attachment portion and the second attachment portion.

19. The system of claim 6, wherein the first attachment portion is further configured to be moved with respect to the second attachment portion to create the strain in a skin treatment device attached to the first attachment portion and the second attachment portion.

20. The system of claim 1, wherein the tensioning element further comprises a force member.

21. The system of claim 20, wherein the tensioning element further comprises a spring.

22. The system of claim 20, wherein the tensioning element further comprises a strut.
