Abstract: An apparatus for applying negative pressure to a tissue site of a patient may include a tissue interface, a cover, an aperture in the cover, and a sealing member. The tissue interface may have an anatomical shape configured to cover the tissue site. The cover may be configured to cover the tissue interface. The aperture in the cover may be fluidly coupled to the tissue interface. The sealing member may be configured to seal the cover to the patient, wherein the cover and the sealing member are configured to cooperate to form a sealed chamber containing the tissue interface. The tissue interface may be coupled to a source of negative pressure, which can be delivered to the tissue interface for distribution to the tissue site. The source of negative pressure may be coupled to the cover of the apparatus.

Abstract: An apparatus for promoting circulation through a subcutaneous lymph vascular network may comprise a first manifold layer, a second manifold layer coupled to the first manifold layer, and a cover layer coupled to the second manifold layer. The first manifold may have a first stiffness, and the second manifold may have a second stiffness greater than the first stiffness. In some embodiments, the apparatus may additionally have a fluid interface configured to fluidly couple at least one of the first manifold layer and the second manifold layer to a fluid conductor through the cover layer. The fluid conductor may be coupled to or configured to be coupled to a source of negative pressure.

IPC: A61H9/00
Abstract: A system and apparatus for promoting perfusion at a tissue site containing a sprain by applying a vacuum to intact skin extending over or surrounding the tissue site. The system and apparatus comprise a manifold formed from a porous material and configured to be disposed proximate the intact skin for distributing vacuum to the intact skin, and a sleeve adapted to cover the manifold and form a chamber containing the manifold to seal the manifold within the chamber between the sleeve and the intact skin. The system and apparatus further comprise a fluid coupling member adapted to deliver vacuum to the manifold for distribution to the intact skin. A method for applying vacuum to the intact skin of a tissue site is also disclosed and described herein.

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: An apparatus for filling a wound can include an array of at least four truncated ellipsoids interconnected to define at least one fluid path through, for example perpendicular to, the array. The longest principal axis of each ellipsoid may be perpendicular to the array. Each truncated ellipsoid may be a spheroid and/or may include an approximately elliptical contact surface at each contact surface between two interconnected ellipsoids. Each fluid pathway may have four continuously-curved concave sides and may have a parallelogram-shaped cross-section with continuously-curved concave edges. A dressing may include the apparatus, a dressing layer coupled to the apparatus, a backing layer disposed over a surface of the dressing layer opposite the apparatus, and an attachment device disposed on at least a margin of the backing layer. Methods of treating various tissue sites using the apparatus or dressing with negative-pressure therapy are also disclosed.
