Systems, methods, and apparatuses are provided for delivering reduced pressure to a subcutaneous tissue site, such as a bone tissue site. In one instance, a manifold for providing reduced pressure to a subcutaneous tissue includes a longitudinal manifold body formed with at least one purging lumen and a reduced-pressure lumen. The manifold further includes a plurality of manifolding surface features or slits formed on the second, tissue-facing side of the longitudinal manifold body and a plurality of apertures formed in the longitudinal manifold body on the second, tissue-facing side. The plurality of apertures fluidly couple the reduced-pressure lumen and the manifolding surface features or slits. The manifold further includes an end cap fluidly coupling the reduced-pressure lumen and the at least one purging lumen. Other systems, apparatuses, and methods are presented.

1. A system for applying reduced pressure to a subcutaneous tissue site on a patient, the system comprising: a reduced-pressure source operable to supply reduced pressure;a fluid source operable to supply a purging fluid;a manifold having a flattened shape including a flat side and an opposing side
1. A system for applying reduced pressure to a subcutaneous tissue site on a patient, the system comprising: a reduced-pressure source operable to supply reduced pressure;a fluid source operable to supply a purging fluid;a manifold having a flattened shape including a flat side and an opposing side opposite the flat side, a width defined by the width of the flat side and a height defined by the distance between the flat side and the opposing side wherein the width is greater than the height, and a distal portion adapted to be inserted in the patient and placed at the subcutaneous tissue site, the manifold comprising: at least one purging lumen formed in the manifold and in fluid communication with the fluid source to deliver the purging fluid to the distal portion of the manifold,at least one slit formed in the flat side only at the distal portion of the manifold and adapted to be facing the subcutaneous tissue site, andat least one reduced-pressure lumen formed in the manifold, the at least one reduced-pressure lumen extending toward the distal end of the manifold and opening toward the flat side of the manifold to become the at least one slit, wherein the at least one reduced-pressure lumen is operable to deliver reduced pressure supplied from the reduced-pressure source to the subcutaneous tissue site via the at least one slit; anda delivery tube in fluid communication with the manifold, the delivery tube having at least one reduced-pressure delivery lumen adapted to deliver reduced pressure to the at least one reduced-pressure lumen and having at least one fluid delivery lumen adapted to deliver the purging fluid to the at least one purging lumen. 2. The system of claim 1, wherein the manifold further comprises at least one interlumen channel fluidly interconnecting at least two of the at least one purging lumen, and the at least one reduced-pressure lumen. 3. The system of claim 1, wherein the at least one slit extends to the distal end of the manifold. 4. An apparatus for applying reduced pressure to a subcutaneous tissue site on a patient, the apparatus comprising: a manifold having a flattened shape including a flat side and an opposing side opposite the flat side, a width defined by the width of the flat side and a height defined by the distance between the flat side and the opposing side wherein the width is greater than the height, and a distal portion adapted to be inserted into the patient and for placement at the subcutaneous tissue site, the manifold comprising: at least one purging lumen formed in the manifold and operable to deliver a purging fluid to the distal portion of the manifold,at least one slit formed in the flat side only at the distal portion of the manifold and adapted to be facing the subcutaneous tissue site,at least one reduced-pressure lumen formed in the manifold, the at least one reduced-pressure lumen extending toward the distal end of the manifold and opening toward the flat side of the manifold to become the at least one slit, wherein the at least one reduced-pressure lumen is operable to deliver reduced pressure to the subcutaneous tissue site via the at least one slit; andan end cap that is attachable to an end of the manifold to form a head space, and wherein the head space is adapted to accumulate fluid from the at least one purging lumen prior to the fluid being drawn via the at least one reduced-pressure lumen. 5. The apparatus of claim 4, wherein the manifold further comprises at least one interlumen channel fluidly interconnecting at least two of the at least one purging lumen, and the at least one reduced-pressure lumen. 6. The apparatus of claim 4, wherein the at least one reduced-pressure lumen terminates at the at least one slit. 7. The apparatus of claim 4, further comprising: a delivery tube in fluid communication with the manifold, the delivery tube delivering reduced pressure to the at least one reduced-pressure lumen and the purging fluid to the at least one purging lumen,wherein the delivery tube has at least one fluid delivery lumen and at least one reduced-pressure delivery lumen,wherein the at least one fluid delivery lumen delivers the fluid to the at least one purging lumen, andwherein the at least one reduced-pressure delivery lumen delivers reduced pressure to the at least one reduced-pressure lumen. 8. The apparatus of claim 4, wherein the manifold is coated with at least one of heparin and parylene. 9. A method for applying reduced pressure to a subcutaneous tissue site, the method comprising: applying a manifold having a flattened shape including a flat side and an opposing side opposite the flat side, a width defined by the width of the flat side and a height defined by the distance between the flat side and the opposing side wherein the width is greater than the height, and a distal portion to the subcutaneous tissue site, the manifold comprising: at least one purging lumen operable to deliver a fluid to the distal portion of the manifold,at least one slit formed in the flat side only at the distal portion of the manifold and adapted to be facing the subcutaneous tissue site, andat least one reduced-pressure lumen extending toward the distal end of the manifold and opening toward the flat side of the manifold to become the at least one slit, the at least one reduced-pressure lumen operable to deliver reduced pressure to the subcutaneous tissue site via the at least one slit;supplying a reduced pressure to the manifold via a reduced-pressure delivery lumen in a delivery tube; andsupplying the fluid to the manifold via a fluid delivery lumen in the delivery tube.
