Patent ID: 8454580

Claim:
A reduced-pressure treatment system for treating a tissue site on a patient, the system comprising: a manifold for placing proximate to the tissue site; an adjustable covering for forming a fluid seal over the manifold and a portion of the patient's epidermis; a reduced-pressure interface coupled to the adjustable covering for providing reduced pressure through the adjustable covering; a reduced-pressure source fluidly coupled to the reduced-pressure interface; and wherein the adjustable covering comprises: a drape member comprising a first drape layer and a second drape layer, wherein the first drape layer has a first perforation pathway and the second drape layer has a second perforation pathway, the first perforation pathway is misregistered from the second perforation pathway, and the drape member has a first initiation edge and a second initiation edge and has a first side and a second, patient-facing side, a plurality of non-leaking tear paths formed on the drape member, wherein each non-leaking tear path comprises a weakened path of the drape member that facilitates tearing of the drape, and an area of misregistration between the first perforation pathway and the second perforation pathway comprises a tear path of the plurality of non-leaking tear paths and a first plurality of tear starters, wherein each tear starter of the first plurality of tear starters is aligned with one of the plurality of non-leaking tear paths, and wherein each of the first plurality of tear starters is adapted to facilitate the initiation of a tear along the one of the plurality of non-leaking tear paths.
