  • Patent number: 10195315
    Abstract: 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.

  • Patent number: 10155074
    Abstract: 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.

  • Patent number: 10137228
    Abstract: 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.
