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: A bodily fluid collection system includes a reduced pressure treatment unit for providing reduced pressure to a fluid collection system through a canister having a container with an inlet adapted to be fluidly coupled to the fluid collection system, an outlet adapted to be connected to a source of reduced pressure, and an absorptive lamination disposed within the container. The absorptive lamination may be formed from a plurality of absorptive layers and wicking layers interleaved between the absorptive layers that collectively manifold bodily fluids from a tissue site into and throughout the absorptive lamination to trap and collect the bodily fluids. The container expands as the absorptive lamination swells with the bodily fluid being collected.

Abstract: A system and apparatus for treating a tissue site with reduced pressure and collecting fluids from the tissue site is disclosed. The system may include a reduced-pressure source, a pouch in fluid communication with the reduced pressure source, and a dressing in fluid communication with the pouch. The pouch may include a first wall, a second wall having a periphery coupled to the first wall to form an interior, and a third wall extending through the interior to form a first chamber in fluid communication with the dressing and a second chamber in fluid communication with the reduced pressure source. A plurality of filters are positioned in the third wall. The filters permit fluid communication between the first chamber and the second chamber.
