Abstract

A reduced pressure delivery system for applying a reduced pressure to a tissue site includes a manifold delivery tube having a passageway and a distal end, the distal end configured to be percutaneously inserted and placed adjacent the tissue site. A flowable material is provided and is percutaneously deliverable through the manifold delivery tube to the tissue site. The flowable material is capable of filling a void adjacent the tissue site to create a manifold having a plurality of flow channels in fluid communication with the tissue site. A reduced pressure delivery tube is provided that is capable of fluid communication with the flow channels of the manifold.

Claims

1. A reduced pressure delivery system for applying a reduced pressure tissue treatment to a tissue site comprising:

a manifold delivery tube having a passageway and a distal end, the distal end configured to be percutaneously inserted and placed adjacent the tissue site;

a flowable material percutaneously deliverable through the manifold delivery tube to the tissue site such that the flowable material is capable of filling a void adjacent the tissue site to create a manifold having a plurality of flow channels in fluid communication with the tissue site;

a reduced pressure delivery tube capable of fluid communication with the flow channels of the manifold; and

a reduced pressure source in fluid communication with the reduced pressure delivery tube to deliver reduced pressure to the flow channels of the manifold;

wherein the manifold delivery tube and the reduced pressure delivery tube are the same tube.

2. The system of claim 1, wherein the manifold is bioresorbable.

3. The system of claim 1, wherein the manifold serves as a scaffold for tissue growth.

4. The system of claim 1, wherein the manifold foams and cures in the presence of at least one of a bodily fluid and a bodily temperature.

5. The system of claim 1, wherein the manifold further comprises a bioresorbable polymer dissolved in a solvent and mixed with sodium bicarbonate and citric acid.

6. The system of claim 5, wherein the bioresorbable polymer is one of a polylactide-co-glycolide (PLAGA) polymer and a polyethylene glycol-PLAGA copolymer.

7. The system of claim 5, wherein the solvent is methylene chloride.

8. The system of claim 1, wherein the flowable material is chosen from the group of a liquid, a slurry, a suspension, a viscous gel, a paste, a putty, and particulate solids.

9. The system of claim 1, wherein:

the flowable material undergoes a phase change in the presence of at least one of a bodily fluid and a bodily temperature; and

the flowable material includes a poragen that dissolves following curing of the flowable material, the dissolution of the poragen creating the plurality of flow channels.

10. The system of claim 1, wherein the flowable material includes microspheres having a coating that is capable of being selectively crosslinked following delivery of the flowable material to the tissue site.

11. The system of claim 10, wherein the coating is selectively crosslinked in response to at least one of heat, light, and a chemical.

12. The system of claim 10, wherein the microspheres following crosslinking create the plurality of flow channels.

13. The system of claim 1, wherein:

the flowable material is chosen from the group of a paste and a putty having an initial viscosity;

the viscosity of the flowable material decreases below the initial viscosity in the presence of shear forces during delivery to the tissue site; and

the viscosity of the flowable material reverts to the initial viscosity following delivery of the flowable material to the tissue site.
