The illustrative embodiments described herein are directed to apparatuses, systems, and methods for applying reduced pressure to subcutaneous tissue site. In one illustrative embodiment, the apparatus includes a sleeve adapted for placement at a subcutaneous tissue site. The sleeve is further adapted to receive a manifold. The sleeve may also have an opening operable to transfer reduced pressure from the manifold to the subcutaneous tissue site. In one embodiment, the apparatus may also include a manifold that is insertable into the sleeve. The manifold may include at least one aperture, and may be operable to deliver reduced pressure to the subcutaneous tissue site via at least one aperture.

1. A system for applying reduced pressure to a subcutaneous tissue site, the system comprising: a sleeve adapted for placement at the subcutaneous tissue site, the sleeve comprising a lumen, a distal end, a proximal end, and an opening;a manifold sized and shaped to be inserted into the lumen of the sleeve, wherein the manifold comprises a plurality of apertures configured to face the opening when the manifold is inserted into the sleeve, and wherein the manifold is operable to deliver reduced pressure to the subcutaneous tissue site through the plurality of apertures and the opening; anda flange disposed along the manifold between the distal end of the sleeve and the plurality of apertures. 2. The system of claim 1, further comprising: a reduced-pressure source operable to supply reduced pressure and a delivery conduit in fluid communication with the manifold, the delivery conduit operable to deliver the reduced pressure to the manifold during treatment. 3. The system of claim 1, wherein the tissue site is within an abdominal cavity. 4. The system of claim 1, wherein the tissue site is proximate a paracolic gutter. 5. The system of claim 1, wherein the sleeve is formed from a flexible material. 6. The system of claim 1, wherein the manifold comprises a fluid passageway for delivering reduced pressure. 7. The system of claim 1, wherein the manifold comprises a fluid passageway for delivering reduced pressure and wherein the passageway extends from a distal end of the manifold to a proximal end of the manifold. 8. The system of claim 1, wherein the manifold has a longitudinal length L1, the sleeve has a longitudinal length L2, and wherein L1>L2. 9. The system of claim 1, wherein the manifold has a longitudinal length L1, the sleeve has a longitudinal length L2, a distance from the subcutaneous tissue site to a location external the patient is L3, and wherein L1>L2>L3. 10. An apparatus for applying reduced pressure to a subcutaneous tissue site, the apparatus comprising: a manifold having a distal end and a proximal end;a sleeve having a distal end and a proximal end, the sleeve sized and shaped for placement at the subcutaneous tissue site, the sleeve having an interior portion for receiving the manifold, the sleeve formed with an opening operable to transfer reduced pressure from the manifold to the subcutaneous tissue site;a flange disposed between the manifold and the sleeve, the flange at least partially surrounding the manifold; andwherein the distal end of the manifold is sized and shaped to be inserted into the interior portion of the sleeve, wherein the manifold is formed with a plurality of apertures disposed between the flange and the proximal end of the manifold and configured to face the opening when the manifold is inserted into the sleeve, and wherein the manifold is operable to deliver reduced pressure to the subcutaneous tissue site through the plurality of apertures. 11. The apparatus of claim 10, wherein the opening formed on the sleeve is located on a side wall of the sleeve, and wherein the opening extends along a length of the sleeve. 12. The apparatus of claim 11, wherein the opening is located proximate the distal end of the sleeve. 13. The apparatus of claim 10, wherein the sleeve is wider than the manifold. 14. The apparatus of claim 10, wherein the sleeve and the manifold have the same cross-sectional shape. 15. The apparatus of claim 10, wherein the flange comprises: an outer edge adapted to at least partially abut the interior portion of the sleeve. 16. The apparatus of claim 15, wherein the outer edge of the flange is slidable along an inner surface of the sleeve. 17. The apparatus of claim 16, wherein the flange is operable to move a substance toward a proximal end of the sleeve when the manifold is removed from the sleeve. 18. The apparatus of claim 15, wherein the flange includes at least one hole. 19. The apparatus of claim 15, wherein the flange is wider than the opening. 20. The apparatus of claim 10, further comprising: an end cap coupled to a distal end of the sleeve. 21. The apparatus of claim 20, wherein the end cap includes a securing wall on a sleeve-facing side of the end cap, and wherein the securing wall is adapted to receive the distal end of the manifold such that the securing wall at least partially surrounds the distal end of the manifold. 22. The apparatus of claim 21, wherein the manifold further comprises at least one projection on the distal end of the manifold, wherein the at least one projection radially extends from the manifold, and wherein the securing wall includes at least one groove that slidably receives the at least one projection. 23. The apparatus of claim 22, wherein the plurality of apertures substantially face the opening when the at least one groove slidably receives at least one projection. 24. The apparatus of claim 10, wherein the sleeve is made from a more flexible material than the manifold. 25. The apparatus of claim 10, wherein the manifold has a longitudinal length L1, the sleeve has a longitudinal length L2, and wherein L1>L2. 26. The apparatus of claim 10, wherein the manifold has a longitudinal length L1, the sleeve has a longitudinal length L2, a distance from the tissue site to a location external the patient is L3, and wherein L1>L2>L3.
