WOUND OR SKIN TREATMENT DEVICES WITH VARIABLE EDGE GEOMETRIES

摘要

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

1. A tissue treatment device, comprising:
an elastic sheet, comprising:
a planar skin interfacing surface;a first undulating edge; anda second undulating edge farthest and opposite from the first 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 with an average amplitude, and a minimum separation of at least 2 mm and an average peak-to-peak distance that is equal to or less than twice the average amplitude.
