Provided are drainage systems that may include a drainage manifold and may be suitable for draining fluid from a tissue site. The drainage manifold may include a plurality of elongate members having a moveable end that may be adapted to configure the drainage manifold to treat a uniquely shaped tissue site. The drainage manifold may be coupled to a drainage tube with a transitional connector to provide a drainage system capable of distributing reduced pressure to the tissue site to enhance the drainage of fluids.

Adaptable wound drainage system

An apparatus and system for providing reduced pressure to a defect in a nerve is disclosed. The apparatus comprises a nerve conduit having a generally tubular shape that has walls including a luminal wall surrounding the tissue site to contain fluids within a luminal space between the tissue site to contain fluids within a luminal space between the tissue site and the luminal wall. The apparatus further comprises a manifold having a porous body and a connector for receiving reduced pressure, wherein the manifold is positioned within the luminal space adjacent the tissue site to distribute the reduced pressure to the defect. Additionally, a method for providing reduced pressure to a defect in a nerve is disclosed that includes implanting the nerve conduit and manifold at a site of damaged nerve tissue and applying a reduced pressure to the manifold thereby stimulating repair or regrowth of nerve tissue.

System for providing fluid flow to nerve tissues

The illustrative embodiments described herein are directed to systems, methods, and apparatuses for applying a reduced pressure to a subcutaneous tissue site. In one instance, a manifold for applying reduced pressure to a subcutaneous tissue site includes a plurality of first conduits, each of the plurality of first conduits having a wall with at least one first aperture and at least one second aperture. At least one of the plurality of first conduits is operable to deliver reduced pressure to the subcutaneous tissue site. The plurality of first conduits is coupled in a spaced arrangement that forms an interior space. The manifold further includes a second conduit comprising the interior space and formed by a portion of each wall of the plurality of first conduits. The second conduit is in fluid communication with the plurality of first conduits via the at least one second aperture.

Multi-conduit manifolds, systems, and methods for applying reduced pressure to a subcutaneous tissue site

An apparatus, system, and method for treating an incisional wound having incisional walls. The apparatus includes a conduit having a first end for receiving reduced pressure and a second end. The apparatus further includes a scaffold. The scaffold has opposing surfaces for positioning adjacent the incisional walls and is fluidly coupled to the second end of the conduit for receiving the reduced pressure. The scaffold is generally elongated in shape and has a thickness between the opposing surfaces that is sufficiently thin for positioning within the incisional wound. The apparatus further includes an internal manifold that has a primary flow channel extending generally longitudinally within the scaffold and between the opposing surfaces of the scaffold. The internal manifold is fluidly coupled to the second end of the conduit. The application of the reduced pressure through the scaffold and the internal manifold induces tissue apposition between the incisional walls.

System and method for sealing an incisional wound

A reduced pressure delivery system for applying reduced pressure tissue treatment to a tissue site is provided. The system includes a manifold delivery tube and a balloon having an inner space. The balloon is capable of assuming collapsed and expanded positions. The system further includes a manifold having a plurality of flow channels. The manifold is disposed within the inner space of the balloon. A sharp tip is configured to be delivered within the manifold delivery tube to puncture the balloon.

System for percutaneously administering reduced pressure treatment using balloon dissection

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.

Manifolds, systems, and methods for administering reduced pressure to a subcutaneous tissue site

Systems, method, and devices are disclosed that involve reconfiguring lumens or unblocking lumens relative to a blockage to maintain flow of reduced pressure to a subcutaneous tissue site. In one instance, a multi-lumen applicator includes an applicator body having a distal end and a proximal end and formed with a plurality of apertures for receiving fluid from the tissue site and for delivering reduced pressure, a first lumen fluidly coupled to the plurality of apertures, a first activation member having at least a closed position and a open position, and a second lumen fluidly coupled to the plurality of apertures but for the first activation member being in closed position. The configuration is such that when the first activation member is moved to the open position, the second lumen is fluidly coupled to the plurality of apertures. Other systems, methods, and devices are disclosed.

Systems and methods for subcutaneous administration of reduced pressure employing reconfigurable lumens

An apparatus and system for treating a wound having a cavity is disclosed. The apparatus has a scaffold including a scaffold lamina and a tissue lamina wherein the scaffold lamina forms a laminate in fluid communication with the tissue lamina. The laminate is rolled into a generally cylindrical shape having two end surfaces. The apparatus further includes a manifold having a port for coupling to a source of reduced pressure and that is positioned in fluid communication with the scaffold to provide reduced pressure to the scaffold lamina and the wound. A method for treating a wound having a cavity is also disclosed and includes positioning a scaffold lamina adjacent a tissue lamina to form a laminate in fluid communication with the tissue lamina, rolling the laminate into a generally cylindrical shape having two end surfaces, and positioning the scaffold within the cavity of the wound.

Tissue roll scaffolds

An apparatus, system, and method for treating an incisional wound having incisional walls is disclosed. The apparatus includes a conduit having a first end for receiving reduced pressure and a second end. The apparatus further includes a scaffold. The scaffold has opposing surfaces for positioning adjacent the incisional walls and is fluidly coupled to the second end of the conduit for receiving the reduced pressure. The scaffold is generally elongated in shape and has a thickness between the opposing surfaces that is sufficiently thin for positioning within the incisional wound. The apparatus further includes an internal manifold that has a primary flow channel extending generally longitudinally within the scaffold and between the opposing surfaces of the scaffold. The internal manifold is fluidly coupled to the second end of the conduit. The application of the reduced pressure through the scaffold and the internal manifold induces tissue apposition between the incisional walls.

Provided is an apparatus that includes a scaffold with a gel or liquid composition deposed on at least a portion of a luminal surface, the gel or liquid composition adapted to include microbubbles. Also provided is a system that includes a source of reduced pressure, the above scaffold, a manifold adjacent the scaffold, and a conduit for providing fluid communication between the manifold and the source of reduced pressure. Additionally provided is a method that includes implanting the above scaffold at the tissue site and disrupting a substantial portion of the microbubbles to induce fluid flow to the scaffold. Further provided is an apparatus that includes a scaffold that comprises a slowly degradable material and a quickly degradable material. Additionally provided is a system for coupling nerve tissue and a microchip assembly.
