Abstract: A transfer dressing that can secure and/or prevent undesired movement of epidermal skin grafts transfer substrates is described. The transfer dressing can include a transfer substrate and one or more adhesive appendages that are configured to secure the transfer substrate to a recipient site (e.g., periwound area) in order to hold the transfer substrate in place and/or facilitate handling of the transfer substrate. The transfer substrate can be comprised of a fenestrated surface configured to facilitate harvesting and transfer of epidermal skin grafts.

Abstract: Provided herein are systems and methods for controlling, inducing, and indicating adhesive deactivation of adhesive drape systems. One aspect provides a system comprising a drape, a photosensitive adhesive layer, and a release agent, where the system is adapted to be coupled to a tissue site and released therefrom after exposure to an external stimulus, such as light. The system may have one or more photosensitive pigment areas that provide a visual indication based on exposure to the light. Another aspect provides a method for controlling the adhesion of a drape by application of a low-tack substance to one or more areas of a drape adhesive. The low-tack substance may be configured to produce a visual indication to distinguish areas where the low-tack substance has been applied. Such systems and methods enable a user to control properties of the drape adhesive and determine the various adhesive states via a visual indication.
