Abstract: Provided herein is a system and method for mitigating premature light deactivation of light deactivated adhesive drapes. One aspect provides a system comprising a drape, a photosensitive adhesive layer, a release agent, and an optical fiber mesh layer configured as a light pipe, where the system is adapted to be coupled to a tissue site and released therefrom upon or after exposure to an external stimulus such as certain wavelengths of light. Another aspect includes a pipe light pipe, as an alternative to the optical fiber mesh layer. The systems may have a removable blocking layer to prevent the photosensitive adhesive from being exposed to deactivation wavelengths prematurely. Another aspect provides a method for application and removal of a drape using the light pipe to transport or route light to the drape to deactivate the photosensitive adhesive layer and promote easy, clean, and less painful removal of the drape.

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.
