Abstract: A canister for use in administering reduced pressure to a tissue site includes a center body, a first end cap, and a second end cap. The center body includes a first end, second end, and a number of fluidly separate body conduits. The first end cap is connected to the first end of the center body and includes a number of return conduits fluidly connecting one body conduit to another. The first end has a port for receiving a conduit in fluid communication with the tissue site. The second end cap is connected to the second end of the center body and includes a number of return conduits fluidly connecting one body conduit to another. The second end cap has a port for receiving a conduit in fluid communication with a reduced pressure source. The fluid connection between the body conduits and the return conduits creates a continuous, tortuous pathway.

Abstract: A system for providing reduced-pressure treatment to a moveable tissue site, such as a joint, includes a flexible dressing bolster. The flexible dressing bolster has a first side and a second, inward-facing side, and a plurality of flexion joints formed on the flexible dressing bolster. The system further includes a sealing subsystem for providing a fluid seal over the flexible dressing bolster and the patient's epidermis and a reduced-pressure subsystem for delivering a reduced pressure to the sealing subsystem. The sealing subsystem and reduced-pressure subsystem are operable to deliver a reduced pressure to the moveable tissue site. The flexible dressing bolster is operable to allow articulation or movement of the moveable tissue site. The sealing subsystem may include a drape with folds. Other systems, apparatuses, and methods are presented.

Abstract: A reduced-pressure system for treating tissue, such as damaged subcutaneous tissue, includes a shaped dressing bolster for placing on the patient's epidermis and substantially sized to overlay the damaged subcutaneous tissue. The system further includes a sealing subsystem for providing a fluid seal over the shaped dressing bolster and a portion of the patient's epidermis, and a reduced-pressure subsystem for delivering a reduced pressure to the sealing subsystem. The reduced-pressure system may develop a force, which may include a vertical force that is realized at tissue site deeper than the epidermis or a closing force directed towards the incision. The shaped dressing bolster is shaped to evenly distribute the force. Other methods and systems are included.

Abstract: An anisotropic wound drape for treating a wound on a patient includes a flexible sheet for placing over a tissue site. The flexible sheet includes a first isotropic zone, and a second isotropic zone. The first isotropic zone and the second isotropic zone are configured to provide the flexible sheet with anisotropic stretching properties. The anisotropic drape may used as part of a reduced-pressure wound treatment system. Other systems and methods are also presented.

Abstract: Dressings, systems, and methods are disclosed, in some embodiments, that involve treating a tissue site with reduced pressure, wherein the dressing includes a dressing reduced-pressure indicator that allows one to ascertain that the reduced pressure applied at the dressing is greater than a threshold reduced pressure. The dressing reduced-pressure indicator may include a moving member that is adapted to move under reduced pressure and a visual indicator associated with the moving member. Another embodiment uses an electro-mechanical indicator to provide a powered visual alert or audible alert or another output signal. Other dressings, systems, and methods are disclosed.

Abstract: A dressing assembly for use with a reduced pressure treatment system, the dressing assembly develops a directed force under reduced pressure. The directed force may be a radial force or a closing force. The dressing assembly includes a shaped dressing bolster having a shaped extremity that is operable to evenly deliver the radial force and to distribute reduced pressure. Numerous shapes may be used for the shaped extremity. The dressing assembly may further include an over-drape to assist in creating a seal over the shaped dressing bolster and against a portion of a patient's epidermis.

Abstract: Provided are systems, dressings, and methods suitable for treating a tissue site, such as an incision or linear wound. The systems, dressings, and methods relate to a dressing assembly that may include a dressing bolster and a sealing ring. The sealing ring may be adapted to provide a fluid seal around the tissue site, and to absorb fluids from the tissue site. In some embodiments, the sealing ring may be extruded around the tissue site. In other embodiments, the sealing ring may be coupled to the dressing bolster. Other systems, apparatuses, and methods are disclosed.
