Abstract
Provided herein is a system and method for facilitating removal of a drape from a tissue site. One aspect provides a system comprising a drape, and adhesive layer, and a release agent, where the system is adapted to be coupled to a tissue site and released therefrom upon or after exposure to an external stimulus. Another aspect provides a method for application and removal of a drape using less force than required with a conventional drape.
Claims7
A system for healing a wound at a tissue site, comprising:
- a drape adapted to cover the wound at the tissue site;
- an adhesive layer having one surface affixed to at least a portion of said drape and an opposite surface adapted to form a bond to the tissue site;
- micelles dispersed within the adhesive layer;
- and
- release material encapsulated in the micelles and releasable from the micelles into the adhesive layer in response to exposure to light, the release material operable to weaken the bond of the adhesive layer to the tissue site;
- whereby the weakening of the bond of the adhesive layer to the tissue site facilitates the removal of the drape from the tissue site.
