Claim 18:
19. A method comprising:
coupling a light deactivated adhesive drape system to a patient's tissue, wherein the light deactivated adhesive drape system includes:
a drape comprising:
a photosensitive adhesive layer having at least one release agent disposed within the adhesive layer, wherein the at least one release agent is configured to weaken a bond of the adhesive layer to the tissue upon exposure to at least one of a plurality of light wavelengths, and
a flexible film layer; and

a photochromic layer configured to darken upon exposure to at least one of a plurality of light wavelengths and change between a plurality of transmittance states, wherein the plurality of transmittance states includes:
a blocking transmittance state configured to block the at least one of the plurality of light wavelengths from passing through the photochromic layer: and

a non-blocking transmittance state configured to allow at least some visible light wavelengths to pass through the photochromic layer:

removing the photochromic layer from the drape system;
exposing the photosensitive adhesive layer to the at least one of the plurality of light wavelengths configured to weaken the bond of the adhesive layer; and
removing the drape from the tissue.
