Abstract
Devices, kits and methods described herein are provided for treatment to skin, including but not limited to wound healing, the treatment, amelioration, and/or prevention of scars or keloids. A book-like packaging, applicator and/or tensioning device can be used to apply a dressing to a subject. The packaging, applicator and/or tensioning device applies and/or maintain a strain in an elastic dressing, and include undulating edge configurations to reduce peak stresses applied to the skin compared to traditional dressing shapes.
Claims18
A tissue treatment device, comprising:
- an elastic sheet, comprising:
- a planar skin interfacing surface;
- a first undulating edge;
- and
- a second undulating edge farthest and opposite from the first undulating edge;
- wherein the elastic sheet further comprises a first tensile stressed configuration and a second tensile stressed configuration;
- wherein the skin interfacing surface is configured to adhere to skin in the first tensile stressed configuration and configured to partially relax to the second tensile stressed configuration to compress the adhered skin;
- wherein the undulating edges are configured to reduce localized tensile stresses at one or more locations along the first undulating edge and the second undulating edge;
- and wherein each undulating edge comprises at least two consecutive extensions each having a peak, an average amplitude, and a minimum separation of at least 2 mm between each extension and an average peak-to-peak distance that is equal to or less than twice the average amplitude.
A method of treating a patient, comprising:
- adhering an elastic sheet in a first stressed configuration to a treatment area, the elastic sheet comprising:
- a planar skin interfacing surface;
- a first undulating edge;
- and
- a second undulating edge farthest and opposite from the first undulating edge;
- wherein the undulating edges are configured to reduce localized tensile stresses at one or more locations along the first undulating edge and the second undulating edge;
- and
- wherein each undulating edge comprises at least two consecutive extensions each having a peak, an average amplitude, and a minimum separation of at least 2 mm between each extension and an average peak-to-peak distance that is equal to or less than twice the average amplitude;
- allowing the elastic sheet in the first stressed configuration to partially relax to a second tensile stressed configuration to compress the adhered skin.
