## Abstract

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.
