    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 therapy device for instillation of fluid to a tissue site is described. The therapy device includes a base having a cartridge receptacle and a support coupled to the base to secure the base to a pole. The therapy device also includes a cartridge configured to engage the base when positioned in the cartridge receptacle. The therapy device also includes a pump head disposed within the cartridge receptacle and configured to engage the cartridge for movement of fluid. The cartridge includes a body forming at least a portion of a fluid reservoir and a tube segment coupled to the body and in fluid communication with the fluid reservoir. The tube segment is configured to engage the pump head.

    Abstract: A reduced-pressure system for delivering reduced pressure for medical purposes to a desired site and to receive fluids in one instance includes a reservoir having an interior space operable to contain the fluids. A reduced-pressure delivery conduit is placed in fluid communication with the interior space for delivering the reduced pressure to the desired site. A source conduit and a pressure sensor conduit are placed in fluid communication with the interior space. A pressure sensor is placed in fluid communication with the pressure sensor conduit. A reduced-pressure source is placed in fluid communication with the source conduit. A reduced-pressure control unit is associated with the pressure sensor and the reduced-pressure source and is operable to receive pressure data from the pressure sensor and supply data from the reduced-pressure source and to determine when a reservoir-full/blockage condition exists. Other systems and methods are presented.

    Abstract: A two-cavity pump having a single valve in one cavity and a bidirectional valve in another cavity is disclosed. The pump has a side wall closed by two end walls for containing a fluid. An actuator is disposed between the two end walls and functions as a portion of a common end wall of the two cavities. The actuator causes an oscillatory motion of the common end walls to generate radial pressure oscillations of the fluid within both cavities. An isolator flexibly supports the actuator. The first cavity includes the single valve disposed in one of a first and second aperture in the end wall to enable fluid flow in one direction. The second cavity includes the bidirectional valve disposed in one of a third and fourth aperture in the end wall to enable fluid flow in both directions.

    Abstract: A manually-actuated, constant reduced-pressure apparatus for use with a reduced-pressure system for treating tissue at a tissue site includes a flexible, collapsible member that is operable to move between a compressed position and an extended position. The collapsible member may be disposed between a carrier member and a slider member that move between a compressed position and an extended position. The carrier member and slider member are urged away from each other by a constant-force biasing member, e.g., a constant force coil spring. As the apparatus moves from the compressed position to the extended position, a constant reduced-pressure is generated and delivered to a reduced-pressure port. Methods of manufacturing a manually-actuated, constant reduced-pressure apparatus and methods of treating a tissue site are also provided.
