1. A device configured for reducing exogenous or endogenous stress experienced by skin tissue comprising:
- a treatment device comprising a sheet and a securing element configured to removably secure the sheet to a skin surface, wherein the treatment device has a first tensile stressed configuration, and a second relaxed configuration wherein the treatment device is configured to stress tissue to reduce stress experienced by skin tissue at or near the treatment device; and
an extending element configured to be extended to form the first tensile stressed configuration prior to application to a skin surface and configured to be released to form the second relaxed configuration;
wherein the extending element is a spring element.

Abstract
Devices, bandages, kits and methods are described that can control or regulate the mechanical environment of a wound to ameliorate scar and/or keloid formation. The mechanical environment of a wound includes stress, strain, and any combination of stress and strain. The control of a wound'"'"'s mechanical environment can be active, passive, dynamic, or static. The devices are configured to be removably secured to a skin surface in proximity to the wound site and shield the wound from endogenous and/or exogenous stress.

15. A method for reducing endogenous or exogenous stress experience by skin tissue comprising:
-
providing a device having a body configured to be removably secured with a securing element to a skin surface; and
an extending element configured to apply tensile stress to the device;before securing the device to the skin surface, applying a tensile stress to the device using the extending element to form a tensile stressed configuration; securing the device to the skin surface of a patient while the device is in the tensile stressed configuration; removing at least some of the tensile stress from the device using the extending element to adopt a partially relaxed configuration that is adapted to stress tissue at or external to the securing element. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25)

26. A method for reducing endogenous or exogenous stress experience by skin tissue comprising:
providing a device having a body configured to be removably secured with a securing element to a skin surface; and
an extending element configured to be extended to form a tensile stressed configuration of the device and to be released from the device to remove the tensile stress from the device, wherein the device is configured to adopt a second relaxed configuration, stressing tissue at or external to the securing element.
