  • Patent number: 11890404
    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.

  • Patent number: 10744040
    Abstract: A closing dressing bolster and assembly for use with a system for treating a linear wound on a patient includes a bolster body formed from a flexible closing bolster material having closing members that are operable to develop an inward closing force when the closing dressing bolster is placed under reduced pressure. In one aspect, when the closing dressing bolster is under reduced pressure, the system, dressing, or assembly develops an inward force realized at the linear wound and a compression force. A wicking-material holder and wicking material may be used as well. The member components may all be see-through to allow visual inspection of the wound without requiring removal of the dressing.

  • Publication number: 20200046565
    Abstract: A system for treating a linear wound on a patient has a closing dressing bolster for placing on the patient's epidermis over the linear wound, a sealing subsystem for providing a seal over the closing dressing bolster and the patient, and a reduced-pressure subsystem for delivering reduced pressure to the sealing subsystem. The sealing subsystem and reduced pressure subsystem are operable to deliver reduced pressure to the closing dressing bolster. The closing dressing bolster is operable under reduced pressure to develop a inward closing. The closing dressing bolster may include one or more closing members on each side of a center wound area to create the inward closing when under reduced pressure. A compressive force may also be developed. Other systems and methods are presented.

  • Patent number: 10076447
    Abstract: A see-through dressing assembly is presented for use with a reduced-pressure system for treating a wound on a patient using reduced pressure that allows visual observation of the wound during treatment. The dressing assembly includes a bolster for providing a directed force when under reduced pressure, a sealing member for covering the bolster and providing a seal over the bolster and a patient's epidermis, and wherein the bolster and sealing member are formed from see-through materials sufficient to allow perception of color from a point external to the system. Other systems, dressings, and methods are presented.
