Dressing for disruption of debris at a tissue site

Abstract

In an example embodiment, a dressing for disrupting debris in a tissue site may comprise a manifold having a first face and a second face. The dressing may also include a plurality of surface features formed from a compressible material. The plurality of surface features may define channels on at least the first face of the manifold. The channels may receive tissue in response to the application of negative pressure. In another example embodiment, a system for softening tissue at a tissue site may include a contact layer. The contact layer may include at least two concentric edges and at least one frangible strut mechanically coupling the concentric edges. The concentric edges and the frangible strut may define through-holes in the contact layer. The through-holes in the contact layer may have an open area in a range of about 0.25 square centimeters to about 15 square centimeters.
