    Abstract: An apparatus for applying negative pressure to a tissue site proximate a patient's foot may include a tissue interface, a sole, a toe box, a cover, and an interface. The tissue interface may be configured to be circumferentially disposed around the tissue site. The sole may be configured to support the tissue interface. The toe box may be coupled to the sole. The cover may be configured to be coupled to the leg and to the sole to cover the tissue interface. The cover and the sole may form a chamber containing the tissue interface and may seal the tissue interface within the chamber. The interface may be configured to fluidly couple the tissue interface to a source of negative pressure, which can be delivered to the tissue interface for distribution to the tissue site.

    Abstract: A super-absorbent dressing assembly for use with a reduced-pressure wound treatment system includes a breathable, fluid restricted dry layer for placement against a wound, a super-absorbent layer, and a non-breathable layer, and a drape extending over the non-breathable layer. A reduced-pressure interface is available to fluidly couple the super-absorbent layer to a reduced-pressure subsystem. The super-absorbent dressing assembly preferably supplies a compressive force when placed under reduced pressure. A reduced-pressure treatment system uses a super-absorbent bolster to treat wounds, e.g., linear wounds.

    Abstract: A system for stimulating the healing of tissue comprises a porous pad positioned within a wound cavity, and an airtight dressing secured over the pad, so as to provide an airtight seal to the wound cavity. A proximal end of a conduit is connectable to the dressing. A distal end of the conduit is connectable to a negative pressure source, which may be an electric pump housed within a portable housing, or wall suction. A canister is positioned along the conduit to retain exudates suctioned from the wound site during the application of negative pressure. A controller for automated oscillation of pressure over time is provided to further enhance and stimulate the healing of an open wound. A power management motor control for varying pump drive frequency and managing a portable power supply is provided to increase battery life and improve patient mobility.

    Abstract: A reduced-pressure treatment system for treating a wound on a patient includes a composite manifold that may help prevent or minimize injury to a wound edge of the wound being treated with reduced pressure. The composite manifold includes a perimeter manifold member and an inboard manifold member. The perimeter manifold member is designed to not collapse substantially under reduced pressure in a therapy range. The perimeter manifold member may be more rigid with respect to compressibility than the inboard manifold member. A sealing member is used to form a fluid seal over the wound, and a reduced-pressure subsystem provides reduced pressure to the composite manifold. Other systems, methods, and dressings are presented.

    Abstract: Systems, devices, and methods for treating a tissue site on a patient with reduced pressure are presented. In one instance, a reduced-pressure interface includes a conduit housing having a cavity divided by a dividing wall into a reduced-pressure-application region and a pressure-detection region. The reduced-pressure interface further includes a reduced-pressure port disposed within the reduced-pressure-application region, a pressure-detection port disposed within the pressure-detection region, and a base connected to the conduit housing, the base having a manifold-contacting surface. The dividing wall includes a surface substantially coplanar with the manifold-contacting surface.
