摘要：
An apparatus, system, and method for closing an opening through a surface of a tissue site is described. The apparatus includes an apposition layer adapted to be positioned over the opening. The apposition layer is formed from a material having a firmness factor, and has a plurality of holes extending through the apposition layer. The holes form a void space and have a perforation shape factor and a strut angle configured to collapse the apposition layer in a first direction relative to a second direction. A sheet having a plurality of perforations is configured to surround the apposition layer, the sheet having a plurality of perforations. The apposition layer generates a closing force in the first direction that is substantially parallel to the surface of the tissue site to close the opening in response to application of a negative pressure.
