Abstract

Devices, kits, systems and methods described herein may be for treatment to skin, including but not limited to wound healing, the treatment, amelioration, and/or prevention of scars or keloids. Devices kits, systems and methods described herein may be used to select treatment parameters or devices for treating skin in a zone or region of skin having particular mechanical or other properties.

Claims

1. A method of treating a subject to ameliorate scar formation, comprising:

measuring a skin tension property of a skin location of a subject;

providing a skin treatment device wherein the skin treatment device comprises;

an elastic member configured to be stretched; and

a securing member configured to couple the skin treatment device to the subject;

then selecting an initial strain amount from a plurality of predetermined strain amounts to be applied to a skin treatment device based on the measured skin tension property of the skin location and applying the initial strain amount to the skin treatment device to form an initial strained configuration;

securing the skin treatment device to the skin of a subject at or near the skin location; and

releasing the skin treatment device from the initial strained configuration while attached to the subject, to thereby offload skin tension at or near the skin location.

2. The method of claim 1, wherein the skin tension property comprises an inherent skin tension.

3. The method of claim 1, wherein the skin tension property comprises a relative skin tension.

4. The method of claim 1, wherein the skin tension property comprises skin stiffness.

19. The method of claim 1, wherein measuring the skin tension property comprises:

applying an energy to the skin location of the subject using a skin interface element; and

measuring the skin tension property based upon a response of the skin location to the skin interface element.

20. The method of claim 19, further comprising providing a visual indicator of the skin tension property.

21. The method of claim 20, wherein measuring the skin tension property is performed using a tool, and the visual indicator is located on the tool.

22. The method of claim 20, wherein selecting a skin treatment device comprises matching the visual indicator of the skin tension property to a corresponding visual indicator on a skin treatment device from a plurality of skin treatment devices.

23. The method of claim 19, wherein the energy is selected from a group consisting of mechanical energy.

24. The method of claim 19, wherein the energy is selected from a group consisting of vibrational energy.

25. The method of claim 19, wherein the energy is selected from a group consisting of acoustical energy.

6. A system for treating a subject, comprising:

11. The system of claim 9, wherein the force property corresponds to a desired offloading of skin tension at a skin location.

12. The method of claim 6, wherein measuring the skin tension property comprises:

applying an energy to the skin location of the subject using a skin interface element; and

measuring the skin tension property based upon a response of the skin location to the skin interface element.

13. A system for treating a subject comprising:

a skin treatment device comprising an elastic member and a securing member configured to couple the device to a skin of a subject, wherein the elastic member has an unstrained configuration and a plurality of selectable strained configurations each having a predetermined strain amount;

a tensioning member configured to strain the skin treatment device to each of the plurality of selectable strained configurations; and

a strain selector configured to indicate a selected one of the plurality of selectable strained configurations of the elastic member; and

wherein the strain selector comprises a skin tension measuring device configured to determine a relative skin tension at a skin location, wherein the skin tension measuring device comprises a plurality of indicators each configured to indicate a different one of the plurality selectable strain values.

14. The system of claim 13, wherein the skin tension measuring device comprises a mechanical skin tensioning structure configured to apply a tension to skin at a skin location, wherein the plurality of indicators correspond to skin response to tension applied by the mechanical skin tensioning structure.
