A reduced-pressure treatment system for applying reduced pressure to a tissue site at a limited-access location on a patient includes a reduced-pressure source, a treatment manifold for placing proximate the tissue site and operable to distribute reduced pressure to the tissue site, and a sealing member for placing over the tissue site and operable to form a pneumatic seal over the tissue site. The reduced-pressure treatment system also includes a reduced-pressure bridge and a moisture-removing device on at least portion of the reduced-pressure bridge. The reduced-pressure bridge includes a delivery manifold operable to transfer the reduced pressure to the treatment manifold, an encapsulating envelope at least partially enclosing the delivery manifold and having a patient-facing side, and a reduced-pressure-interface site formed proximate one end of the reduced-pressure bridge.
