Abstract: Systems, methods, and apparatuses for debriding a tissue site are described. The system includes a manifold and a cover adapted to form a sealed space over the tissue site for providing negative pressure. The system also includes a debridement tool positioned between the manifold and the tissue site. The debridement tool having a tissue-facing surface and a plurality of holes separated from each other by walls. The walls have transverse surfaces extending between the tissue-facing surface and an opposite surface that form cutting edges. The holes have a perforation shape factor that allows the holes to collapse from a relaxed position to a contracted position in response to the application and removal of negative pressure from the sealed space. The cutting edges debride the tissue site in response to movement between the relaxed position and the contracted position.

Abstract: A method and apparatus for disrupting material at a tissue site is described. A contact layer may be selected for use on the tissue site and positioned adjacent to the tissue site. The contact layer may include walls defining a plurality of through-holes. A sealing member may be positioned over the contact layer and sealed to tissue surrounding the tissue site to form a sealed space enclosing the contact layer. A negative-pressure source may be fluidly coupled to the sealed space. The negative-pressure source may supply negative pressure to the sealed space and the contact layer to draw tissue into the through-holes to form nodules. The negative pressure may be vented from the sealed space to release the nodules.
