Abstract: Systems, apparatuses, and methods for closing an opening through a surface of a tissue site are described. The system includes a sealing member adapted to cover the opening to form a sealed space and a negative-pressure source adapted to be fluidly coupled to the sealed space to provide negative pressure to the sealed space. The system also includes a contracting layer adapted to be positioned adjacent the opening and formed from a material having a firmness factor and a plurality of holes extending through the contracting layer to form a void space. The holes have a perforation shape factor and a strut angle causing the plurality of holes to collapse in a direction substantially perpendicular to the opening. The contracting layer generates a closing force substantially parallel to the surface of the tissue site to close the opening in response to application of the negative pressure.

Abstract: In some illustrative examples, a medical drape suitable for treating a tissue site may include an adherent surface including first adherent force profile oriented along a first axis and a second adherent force profile oriented along a second axis. The first adherent force profile may have an average force less than an average force of the second adherent force profile. Other apparatuses, systems, and methods are also provided.
