Embodiment Construction

[0061] Previous attempts to treat scars and keloids have included surgery, silicone dressings, steroids, x-ray irradiation and cryotherapy. Each of these techniques has disadvantages. Perhaps the biggest downside is that none of them are effective in preventing or improving scars or keloids in the first place. That is, these techniques are primarily used to treat scars after they have definitely formed.

[0062] Unloading of exogenous and / or endogenous stress in the vicinity of the wound can improve the formation of scars, hypertrophic scars or keloids. The mechanical environment of an injury may be an important factor in the tissue response to that injury. The mechanical environment includes exogenous stress (i.e., physiological stress, which includes stress transmitted to the wound by muscular action or physical body movement) and endogenous stress (i.e., skin stress arising from the physical properties of the skin itself, including Stress induced at the wound site due to...

Abstract

Devices, kits 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. An applicator and / or tensioning device may be used to apply a dressing to a subject. The applicator and / or tensioning device applies and / or maintains a strain in an elastic dressing, wherein at least some of the strain is out-of-plane or at a non-orthogonal, non- parallel and non-aligned orientation to other strains in the dressing.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit under 35 U.S.C. §119(e) of U.S. Provisional Application Serial No. 61 / 596,708, filed February 8, 2012, which is hereby incorporated by reference in its entirety. This application is related to US Patent Application Serial No. 12 / 854,859, filed August 11, 2010, and US Patent Application Serial No. 13 / 345,524, filed January 6, 2012, both of which are incorporated herein by reference in their entirety. Background technique [0003] Scarring from skin injury is part of the natural wound healing process. Wound healing is a long and continuous process, although it is generally considered to occur in stages. The process begins immediately after injury, with a period of inflammation. In this phase, which usually lasts 2 days to 1 week (depending on the wound), injured tissue and foreign objects are removed from the wound. The proliferative phase occurs at a later time than the inflammatory ...
