OG exemplary drawing
 
1. A drape comprising:
a first region including a first adhesive material, the first adhesive material having a first tackiness; and
at least a second region including a second adhesive material, the second adhesive material having a second tackiness in a first phase and a third tackiness in a second phase, the third tackiness greater than the second tackiness, wherein the first adhesive material is configured to maintain the first tackiness when the second adhesive material is in the second phase, and wherein the first tackiness is the same as the second tackiness.
 
25. A method of using a drape, the method comprising:
attaching a drape to a tissue site, the drape comprising a first region including a first adhesive material and a second region including a second adhesive material, the first adhesive material having a first tackiness and the second adhesive material having a second tackiness in a first phase and a third tackiness in a second phase, wherein the first tackiness is the same as the second tackiness, and the third tackiness greater than the second tackiness; and
applying an energy input to the second region to transition the second adhesive material from the first phase to the second phase.
 
26. A method of manufacturing a drape, the method comprising:
covering a first region of a drape with a first adhesive having a first tackiness;
disposing an encapsulated second adhesive to a second region of the drape, the encapsulated second adhesive having a second tackiness that is greater than the first tackiness; and
covering the second region of the drape and the encapsulated second adhesive with the first adhesive.
 
27. A method of using a drape, the method comprising:
receiving, at a second region of a drape, an energy input, the drape comprising a first region including a first adhesive material and the second region including a second adhesive material, the first adhesive material having a first tackiness and the second adhesive material having a second tackiness in a first phase and a third tackiness in a second phase, wherein the first tackiness is the same as the second tackiness, and the third tackiness greater than the second tackiness;
responsive to receiving the energy input, transitioning the second adhesive material from the first phase to the second phase.
 
28. A kit for wound therapy, the kit comprising:
a drape comprising:
a first region including a first adhesive material, the first adhesive material having a first tackiness; and
at least a second region including a second adhesive material, the second adhesive material having a second tackiness in a first phase and a third tackiness in a second phase, wherein the first tackiness is the same as the second tackiness, and the third tackiness greater than the second tackiness, and wherein the first adhesive material is configured to maintain the first tackiness when the second adhesive material is in the second phase; and
a wound therapy device configured to be coupled to the drape.
