Manifolds, systems, and methods for administering reduced pressure to a subcutaneous tissue site
View Patent ↗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 manifold for providing reduced pressure to a subcutaneous tissue site on a patient, the manifold comprising: a longitudinal body including at least one purging lumen and a reduced-pressure lumen, the longitudinal body having a first side and a second side adapted to face the tissue site; a plurality of manifolding surface features formed on the second side of the longitudinal body; a plurality of apertures formed in the longitudinal body on the second side, wherein the plurality of apertures fluidly couple the reduced-pressure lumen and the plurality of manifolding surface features; and an end cap disposed on a distal end of the longitudinal body and fluidly coupling the reduced-pressure lumen and the at least one purging lumen through a header space in the end cap.
2. The manifold of claim 1 , wherein the plurality of manifolding surface features comprise a plurality of recesses.
3. The manifold of claim 1 , wherein the plurality of manifolding surface features comprise a plurality of offsets.
4. The manifold of claim 1 , wherein the end cap is formed integrally with the longitudinal body.
5. The manifold of claim 1 , wherein the longitudinal body has an aspect ratio greater than 10.
6. The manifold of claim 1 , wherein the longitudinal body and the plurality of manifolding surface features comprise a bioreabsorbable material.
7. The manifold of claim 1 , wherein the plurality of manifolding surface features are bioreabsorbable.
8. The manifold of claim 1 , wherein the plurality of manifolding surface features are detachable and are operable to detach when percutaneously removed from the patient.
9. A system for treating a subcutaneous tissue site on a patient with reduced pressure, the system comprising:
a reduced-pressure source;
a manifold comprising:
a longitudinal body having at least one purging lumen and a reduced-pressure lumen, the longitudinal body having a first side and a second-side adapted to face the tissue site,
a plurality of manifolding surface features formed on the second side of the longitudinal body,
a plurality of apertures formed in the longitudinal body on the second side, wherein the plurality of apertures fluidly couple the reduced-pressure lumen and the plurality of manifolding surface features, and
an end cap disposed on a distal end of the longitudinal body and fluidly coupling the reduced-pressure lumen and the at least one purging lumen through a header space in the end cap; and
a reduced pressure delivery tube coupling the reduced-pressure source and the manifold.
10. The system of claim 9 , wherein the plurality of manifolding surface features comprise a plurality of recesses.
11. The system of claim 9 , wherein the plurality of manifolding surface features comprise a plurality of offsets.
12. The system of claim 9 , wherein the end cap is formed integrally with the longitudinal body.
13. The system of claim 9 , wherein the longitudinal body has an aspect ratio greater than 10 .
14. The system of claim 9 , wherein the longitudinal body and the plurality of manifolding surface features comprise a bioreabsorbable material.
15. The system of claim 9 , wherein the plurality of manifolding surface features are bioreabsorbable.
16. The system of claim 9 , wherein the plurality of manifolding surface features are detachable and are operable to detach when percutaneously removed from the patient.
