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.

1. A method for delivering reduced pressure to a tissue site at a limited-access location, the method comprising the steps of: disposing a first manifold proximate the tissue site;disposing a sealing member over the first manifold, the sealing member having a first aperture;providing a reduced-pressure bridge having a first end and a second end, the reduced-pressure bridge having a second aperture proximate the first end and having a second manifold and a moisture-removing device;coupling a reduced-pressure interface to the second end of the reduced-pressure bridge;disposing the first end of the reduced-pressure bridge over at least of portion of the sealing member with the second aperture substantially aligned with the first aperture; andfluidly coupling a reduced-pressure source to the reduced-pressure interface. 2. The method of claim 1 wherein the moisture-removing device comprises a wicking layer. 3. The method of claim 1 wherein the moisture-removing device comprises a comfort manifold and an encapsulating member for encapsulating at least a portion of the comfort manifold on a patient-facing side of the reduced-pressure bridge and wherein the encapsulating member has a plurality of apertures. 4. The method of claim 1, wherein the reduced-pressure bridge comprises: the second manifold operable to transfer the reduced pressure to the first manifold,a first encapsulating envelope at least partially enclosing the second manifold and having a patient-facing side,a reduced-pressure-interface site formed proximate the second end of the reduced-pressure bridge,the second aperture formed on the patient-facing side of the first encapsulating envelope, wherein the reduced pressure is transferred to the tissue site via the second aperture, andthe moisture-removing device on at least a portion of the first encapsulating envelope. 5. The method of claim 4, wherein the first encapsulating envelope comprises: a first encapsulating member having a first perimeter portion;a second encapsulating member having a second perimeter portion; andwherein the first perimeter portion is coupled to the second perimeter portion such that the second manifold is at least partially enclosed by the first encapsulating member and the second encapsulating member. 6. The method of claim 4, wherein the moisture-removing device comprises a wicking material on the patient-facing side of the first encapsulating envelope, the wicking material adapted to contact a remote tissue portion and to absorb liquid from the remote tissue portion, and wherein the wicking material extends along a length of the first encapsulating envelope. 7. The method of claim 4, wherein the first encapsulating envelope comprises a polyurethane material. 8. The method of claim 4, wherein the reduced-pressure bridge has a length (L) that extends from the tissue site to a remote location, and wherein L>120 mm. 9. The method of claim 4, wherein the reduced-pressure bridge has a length (L) that extends from the tissue site to a remote location, and wherein L>200 mm. 10. The method of claim 4, wherein the reduced-pressure bridge has a length (L) and a width (W) and wherein L>(4*W). 11. The method of claim 4, wherein the second manifold is a foam material. 12. The method of claim 4, wherein the wicking material comprises a cloth-material drape. 13. The method of claim 4, wherein the wicking material comprises a non-woven fabric. 14. The method of claim 4, wherein the wicking material covers at least 50 percent of a patient-facing side of the first encapsulating envelope. 15. The method of claim 4, wherein the wicking material covers at least 70 percent of a patient-facing side of the first encapsulating envelope. 16. The method of claim 4, wherein the wicking material covers at least 80 percent of a patient-facing side of the first encapsulating envelope. 17. A method for delivering reduced pressure to a tissue site at a limited-access location, the method comprising the steps of: disposing a treatment manifold proximate the tissue site;disposing a sealing member over the treatment manifold, the sealing member having a first aperture;providing a reduced-pressure bridge having a first end and a second end, the reduced-pressure bridge having a second aperture proximate the first end and having a delivery manifold and a moisture-removing device;coupling a reduced-pressure interface to the second end of the reduced-pressure bridge;fluidly coupling the first end of the reduced-pressure bridge to the first aperture of the sealing member; andfluidly coupling a reduced-pressure source to the reduced-pressure interface. 18. The method of claim 14, wherein the moisture-removing device comprises a wicking layer. 19. The method of claim 14, wherein the moisture-removing device comprises a comfort manifold and an encapsulating member for encapsulating at least a portion of the comfort manifold on a patient-facing side of the reduced-pressure bridge and wherein the encapsulating member has a plurality of apertures.
