Systems, apparatuses, and methods for providing negative pressure to a tissue site are disclosed. Illustrative embodiments may include an apparatus or system comprising a dressing for treating a tissue site with negative pressure. For example, the dressing may comprise or consist essentially of a manifold and a contact layer. In some embodiments, the manifold may have a tubular shape with a central axis. The contact layer may comprise a polymer film completely or substantially enclosing the manifold in some examples. In further embodiments, the dressing may comprise a plurality of fluid restrictions in the contact layer, the fluid restrictions configured to open or expand in response to a pressure gradient across the polymer film.
