    Abstract: According to an illustrative embodiment, a system for treating a wound at a tissue site of a patient comprising a reduced-pressure source to supply reduced pressure, a drape adhering to the tissue site to cover the wound where possible leak passages between the drape and the tissue site may occur, and a seal disposed between the drape and the tissue site, is disclosed. The seal is adapted to react with a fluid to form a sealant substantially filling the passages in response to air leaking through the passages from outside the drape when reduced pressure is applied to the wound. According to another illustrative embodiment, a method for sealing a drape to a tissue site for treating a wound at the tissue site comprising applying the drape to cover the tissue site whereby passages are formed between the drape and the tissue site, positioning a seal between the drape and the tissue site wherein the seal is adapted to react with a fluid to form a sealant for substantially filling the passages, is also disclosed.

    Abstract: A wound therapy system includes a negative pressure circuit, a pump, a pressure sensor, and a controller. The negative pressure circuit applies negative pressure to a wound. The pump is fluidly coupled to the negative pressure circuit and produces a negative pressure at the wound or within the negative pressure circuit. The pressure sensor measures the negative pressure within the negative pressure circuit or the wound. The controller performs a testing procedure including a first drawdown period, a leak rate determination period, a vent period, and a second drawdown period. The controller is configured to receive one or more pressure measurements of the pressure sensor over the leak rate determination period to determine a leak rate parameter, monitor an amount of elapsed time over the second drawdown period to determine a drawdown parameter, and estimate a volume of the wound based on the leak rate parameter and the drawdown parameter.

    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: Methods and devices for treatment of damaged tissue are disclosed, including treatment of wounds by employing non-electrically powered, reduced pressure therapy devices. Maintenance and control of the sub atmospheric pressure exerted may be provided by such devices while minimizing discomfort to the user. The devices may be configured to be worn inconspicuously underneath clothing.

    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.
