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.

Abstract: A system, apparatus, and method for treating a tissue site with reduced pressure includes a connector having a connector body. The connector body includes a cavity and a cavity aperture. The connector also includes a conduit port fluidly coupling a conduit to the cavity. The connector further includes a base adjacent the cavity aperture that is configured to be positioned adjacent a drape. The cavity is configured to be fluidly coupled to a manifold through an aperture of the drape. The connector also includes a sensing probe having a proximal end configured to be fluidly coupled to the conduit and a distal end extending to the cavity aperture. The distal end is configured to be positioned adjacent to and in fluid communication with a manifold.

Abstract: Inline storage pouches and systems for receiving and retaining body fluids from an animal are presented. The inline storage pouch include a flexible pouch body has an interior portion with a fluid storage material disposed within the interior portion. In addition to receiving body fluids, the inline storage pouch may fluidly couple a pressure sensing conduit between a first port and a second port using a first bypass conduit. The first port may be a patient-port interface. The second port may be a device-port interface. Multiple sensors and bypass conduits may be included and associated with a microprocessor that is configured to locate blockages or determine when the inline storage pouch is full. Another inline storage pouch has two chambers and receives and discharges fluids from a pouch connector. Other pouches, systems, and methods are presented herein.

Abstract: Wound dressings, systems, and methods are presented for treating a wound on a patient's limb, such as a venous leg ulcer. The dressings, systems, and methods involve creating airflow within the dressing to vaporize and remove liquid. The airflow may begin when the dressing becomes saturated. The dressings may be used to provide compression and reduced pressure to the wound. Other systems, methods, and dressings are presented herein.

Abstract: In some illustrative examples, a bridge suitable for treating a tissue site may include a bridge sealing member and one or more bridge wicking layers. The bridge sealing member may extend along a length of the bridge, and may define an internal passageway in fluid communication between a receiving end of the bridge and a transmitting end of the bridge. The one or more bridge wicking layers may be disposed within the internal passageway of the bridge sealing member. Other apparatus, systems, and methods are disclosed.

Abstract: Disclosed embodiments relate to devices and systems for providing both negative-pressure therapy and instillation, In some embodiments, both negative-pressure and instillation may be provided to a tissue site in a low-profile context that may also prevent siphoning of instillation fluid during negative pressure application. For example, a single bridge may include a negative-pressure pathway with supports and an instillation pathway, and the instillation pathway may be configured with respect to the negative-pressure pathway so that at least a portion of the instillation pathway collapses upon application of negative pressure to the negative-pressure pathway. Collapse of at least a portion of the instillation pathway may be sufficient to close the instillation pathway.
