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.
Claims24
A dressing system, comprising:
- a dressing comprising a first edge and a second edge, wherein the second edge has a an orientation that is non-parallel and non-orthogonal to the first edge when the dressing is in an unstrained state, and a first face comprising an adhesive;
- and
- a frame removably attached to the dressing and supporting the first edge and the second edge of the dressing, the frame comprising an outer edge, an inner edge, and an opening surrounded by the inner edge.
A dressing system comprising a dressing with an unstrained circular or oval shape and a strained circular or oval shape wherein the strain on a first transverse dimension is the same as the strain on a second transverse dimension that is not aligned, parallel or orthogonal to the first transverse dimension.
A dressing system comprising a straining structure, a dressing and a frame configured to releasably retain an elastic dressing, wherein the straining structure and the frame are configured to apply a first straining force to the dressing that is orthogonal to a first edge of the dressing and a second straining force to the dressing that is orthogonal to a second edge of the dressing, wherein the second straining force of the dressing is higher than straining force to the dressing that is orthogonal to a third and fourth edge of the dressing that are located to each side of the second edge.
A method of straining a dressing, comprising:
- straining a first dressing region along a first axis located in a first plane;
- straining a second dressing region along a second axis located in a second plane different from the first plane, wherein the second dressing is coupled to the first dressing region;
- and
- applying the first dressing region to a treatment site;
- and
- releasing at least some strain from the first dressing region.
