Abstract: A wound fluid collection system includes a canister adapted to collect bodily fluids from a tissue site. The canister includes an acoustic transducer adapted and positioned to insonify a cavity within the canister, the cavity being defined by a wall of the canister and the bodily fluids collected within the canister. A resonant frequency may be calculated based on a resulting received signal from the insonification. The resonant frequency may indicate a volume of the cavity within the canister. The difference between a known volume of the canister and the calculated volume of the cavity provides the volume of bodily fluid collected in the canister.

Abstract: Methods and systems for treating a wound using targeted delivery of magnetically-tagged active agents in combination with negative pressure wound therapy are presented. In particular, a magnetically-active wound insert may be used to attract magnetically-tagged stem cells to a wound site to treat the wound.

Abstract: Systems, methods, and devices are presented for treating a tissue site and managing hair proximate the tissue site. A composition is provided for inhibiting, removing, or weakening hair proximate the tissue site and for providing an improved fluid seal by a flexible film drape over the tissue site. In some example embodiments, a hair-modification agent is disposed at least proximate a peripheral edge of a treatment manifold between a drape and epidermis proximate a tissue site. The hair-modification agent can be configured to flow over imperfections on the epidermis and to form a fluid seal against the epidermis, and can further be configured to at least substantially weaken hair on the epidermis as the hair encounters the hair-modification agent.

Abstract: Wounds dressings, systems, and methods are presented for removing liquid from a wound site into a dressing and moving air through the dressing to evaporate at least a portion of the removed liquid. The air is moved in one instance by a Coanda device incorporated into the dressing. Other systems, dressings, and methods are presented.

Abstract: A surface-wound healing dressing for a wound or incision includes a slip drain located within the closed wound or incision. A wick is placed over the closed wound or incision in contact with the slip drain. A mat is placed over the wick and adapted for fluidic communication therewith. A recoil core includes a foam material and is adapted for placement on the mat. A wound healing method includes the steps of placing a slip drain, placing a wick over the slip drain, placing a recoil core over the wick and covering the recoil core with an overdrape. The overdrape is adapted for connection to an external negative pressure source, such as a vacuum.

Abstract: Systems, methods, and apparatuses arc presented that involve forming patterns on neo-epithelium that allow increased functionality and may more nearly resemble the original epithelium. In one instance, a patterned neo-epithelium dressing for treating a tissue site having granulation tissue includes an interface member for placing proximate the granulation tissue and a plurality of three-dimensional features formed on a second, patient-facing side of the interface member. Other systems, methods, and apparatuses are disclosed.

Abstract: Systems, methods, and dressings for treating a linear wound, such as an incision, on a patient are presented. The systems, dressings, and methods involve a sealed wound dressing assembly that helps form a fluid seal around the linear wound while simultaneously encompassing a subcutaneous delivery conduit to deliver fluid to or from a subcutaneous tissue site. In one instance, a reduced-pressure interface is used to allow the subcutaneous delivery conduit to pass through tissue at or near the linear wound and through a wound dressing assembly to a drainage receptacle.

Abstract: In some embodiments, a dressing assembly may include a dressing bolster, an interface seal, and a base layer. The dressing bolster may include a first side, a second side, and a periphery. The interface seal may be coupled at the periphery of the dressing bolster. The base layer may include a base layer flange configured to be coupled to the dressing and to extend beyond the periphery of the dressing bolster. The dressing assembly may be suitable for treating a tissue site with reduced pressure and for creating an apposition force between a first portion of the tissue site and a second portion of the tissue site. Other systems, apparatus, and methods are disclosed.
