Abstract: A dressing for treating a tissue site, which may comprise a tissue interface and a cover comprising an expansion zone configured to be disposed over the tissue interface. The tissue interface may comprise a tissue contact layer having a treatment aperture in some examples. In more particular examples, the cover may be coupled to the tissue contact layer to form an expansion chamber between the expansion zone and the tissue contact layer. The cover may also comprise a base coupled to the tissue contact layer in some examples. Additionally, the tissue interface may further comprise an absorbent disposed within the expansion chamber in some embodiments. In some examples, the absorbent may be a manifold. Additionally or alternatively, the expansion chamber and the absorbent may be detachable.
