  • Publication number: 20110230809
    Abstract: Systems, methods, and apparatuses are presented that involve forming patterns on neo-epithelium that allow increased functionality and may more nearly resemble the original epithelium. In one instance, a patterned neo-epithelium dressing for treating a tissue site having granulation tissue includes an interface member for placing proximate the granulation tissue and a plurality of three-dimensional features formed on a second, patient-facing side of the interface member. Other systems, methods, and apparatuses are disclosed.

  • Publication number: 20110230848
    Abstract: Methods, dressings, and systems for promoting epithelialization of a wound or other tissue are presented. The methods, dressings, and systems help form simulated rete pegs. In one instance, an epithelialization dressing is disclosed that may include a dressing body having a plurality of projections. A plurality of apertures is formed on a portion of the dressing body. The dressing helps manage fluids on the wound and the projections form cavities into which epithelial tissue migrates to from epithelial columns that function like rete pegs. Other dressings, methods, and systems are disclosed.

  • Publication number: 20100179515
    Abstract: An apparatus and system for treating a wound having a cavity is disclosed. The apparatus comprises 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 comprises 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. The apparatus also comprises a drape formed of substantially impermeable material to cover the scaffold and the manifold within the wound.

  • Publication number: 20100168625
    Abstract: Provided is an apparatus that includes a nerve conduit, a manifold and a support structure for providing a reduced pressure. Also provided is a system that includes a source of reduced pressure, a nerve conduit, a manifold, a support structure and a conduit for providing fluid communication between the manifold support and the source of reduced pressure. Additionally provided is a method that includes implanting the above nerve conduit, manifold and support structure at a site of damaged nerve tissue and applying a reduced pressure to the manifold thereby stimulating repair or regrowth of nerve tissue.

  • Publication number: 20100168867
    Abstract: Provided are apparatuses, systems, and methods for treating tissue at a tissue site in a mammal that includes a scaffold adapted to be disposed adjacent to the tissue site and to be fluidly coupled to a blood vessel of the mammal for receiving blood therefrom. Additionally, a scaffold is provided that includes a charged surface comprising a streaming potential.

  • Publication number: 20100168720
    Abstract: Provided is an apparatus that includes a nerve conduit and a nested manifold for providing a reduced pressure. Also provided is a system that includes a source of reduced pressure, a nerve conduit and nested manifold, 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 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.

  • Publication number: 20100168689
    Abstract: 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.
