1. An apparatus for managing fluid in a system for treating a tissue site, the apparatus comprising:
a first polymeric film having an outer surface, and an inner surface, the first polymeric film forming a plurality of features extending from the inner surface, the first polymeric film being non-porous;
a second polymeric film having an outer, tissue-facing surface and an inner surface, the second polymeric film coupled to the first polymeric film and covering the plurality of features to form an enclosed space between the inner surface of the first polymeric film and the inner surface of the second polymeric film and a plurality of flow channels within the enclosed space, the second polymeric film having an aperture open to the enclosed space and adapted to fluidly couple the enclosed space to the tissue site;
a first wall coupled between the inner surface of the first polymeric film and the inner surface of the second polymeric film, the first wall extending a length of the enclosed space from the aperture to an opposite end, the first wall forming a first fluid pathway and a second fluid pathway within the enclosed space in fluid communication through the aperture; and
a port fluidly coupled to the first fluid pathway and the second fluid pathway.
