1. An apparatus for managing fluid at a tissue site, the apparatus comprising:
a negative-pressure pathway comprising a first layer and a second layer being coupled to each other to form an enclosed space between the first layer and the second layer, and a first spacer layer and a second spacer layer;
a plurality of supports disposed within the enclosed space between the first layer and the second layer, the plurality of supports comprises a first plurality of supports extending inward from the first spacer layer and a second plurality of supports extending inward from the second spacer layer configured to support the negative-pressure pathway; and
an instillation pathway, wherein the instillation pathway is located between the first spacer layer and the second spacer layer, and wherein the instillation pathway is further located between the first plurality of supports and the second plurality of supports configured to interact with the negative pressure pathway so that at least a portion of the instillation pathway collapses upon application of the negative pressure to the negative-pressure pathway, the instillation pathway comprising a collapsible conduit configured to interact with the plurality of supports so that the collapsible conduit collapses along its length upon application of negative pressure to the negative-pressure pathway.
