The present disclosure relates to apparatus for covering a burn or other wound in ways that prevent or limit touching the wound. The present disclosure describes Burn Bandages that may include domes or structures that bridge over a wide range of a burn or wound size. In certain instances these structures may expand in one or more directions as they are adjusted to fit to a particular burn or wound size. Such bridging structures may include airways, openings, or voids that promote air/oxygen flow to the wound as the Burn Bandage sits upon surfaces or pads that contact healthy surrounding tissue while they cover a wound site. The apparatus may be any shape including, yet not limited to, a circle, a rectangle, a square, a hexagon, an octagon, an oval, a cone, a cylinder, have a semi-cylindrical shape, or that have any another geometric shape.

A wound dressing containing a multi-ply knit fabric, where the fabric contains a first and a second knit ply. The first knit ply contains a plurality of first yarns and forms the upper surface of the fabric. The second knit ply contains a plurality of polytetrafluoroethylene (PTFE) yarns, where the PTFE yarns have a transmission in the IR region of 8-10 μm at least about 40%, and a thermal conductivity of at least about 0.2 W/(m.Math.K) forms the lower surface of the fabric. The first ply and the second ply are integrated through combined portions formed by interlacing first yarns among the PTFE yarns of the second knit ply, interlacing PTFE yarns among the first yarns of the first knit ply, or interlacing a plurality of third yarns among the first yarns and the PTFE. The multi-ply knit fabric also contains a composition containing at least one silver ion-containing compound.

A medical gauze and gas flow assembly and method of applying a medical gauze with gas flow over a wound, provides a medical dressing cover that couples to a gas flow framing structure. The gas flow framing structure provides a flow of gas over a wound. A medical grade gauze material adheres to the lower surface of the medical dressing cover, so as to create spacing between the medical grade gauze material and the wound treatment area. The gas flow is directed between the medical grade gauze material and the wound treatment area. The gas flow vents to ambient though the gas permeable medical dressing cover. When degraded, the assembly is replaced or only the medical dressing cover and medical grade gauze material is replaced. The synergistic combination of a medical grade gauze material that is a gas permeable, with a gas flow structure that discharges gas over the wound enhances healing the wound.

Embodiments disclosed herein are directed to the treatment of wounds using negative pressure. Some embodiments disclosed herein provide for a foam pad, which may be suitable for use in abdominal wound sites, and which may be sized in a dimensionally-independent manner. Additional embodiments provide for a wound contact layer, as well as a system for the treatment of abdominal wounds.

An apparatus for filling a wound can include an array of at least four truncated ellipsoids interconnected to define at least one fluid path through, for example perpendicular to, the array. The longest principal axis of each ellipsoid may be perpendicular to the array. Each truncated ellipsoid may be a spheroid and/or may include an approximately elliptical contact surface at each contact surface between two interconnected ellipsoids. Each fluid pathway may have four continuously-curved concave sides and may have a parallelogram-shaped cross-section with continuously-curved concave edges. A dressing may include the apparatus, a dressing layer coupled to the apparatus, a backing layer disposed over a surface of the dressing layer opposite the apparatus, and an attachment device disposed on at least a margin of the backing layer. Methods of treating various tissue sites using the apparatus or dressing with negative-pressure therapy are also disclosed.

Disclosed embodiments related to a wound dressing for treating circumferential wounds for use in a negative pressure wound therapy (NPWT). The wound dressing can include a cover layer, a plurality of spacer sections, and a wound contact layer. The wound dressing can further include a port for connection to a source of negative pressure and a connector for fluidically connecting each of the plurality of sections with the port.

A wound dressing for a burn or open wound is formed of a foam material body with an open center area. The thickness of the foam body creates a zone for air circulation and prevents contact with the wound. This may have a mesh, gauze or other air permeable cover over the open center area.

Systems, instruments, methods, and compositions are described involving removing a portion of the epidermis within a donor site on a subject, and harvesting dermal plugs within the donor site. An injectable filler is formed by mincing the dermal plugs. The injectable filler is configured for injecting into a recipient site on the subject.

An improved abdominal hernia repair system is presented comprised of a silicone layer backed up with a knitted or woven polypropylene fabric layer, the silicone layer possessing a regular pattern of slits that permit equilibration of fluid pressure across the device. A variety of therapeutic substances can be applied to the hernia repair device to promote healing, including aloe and other medicinal preparations. A layer of water soluble or water insoluble anti-scar compound is also present, the preferred compound being Salinomycin.

An improved inguinal hernia repair system is presented that is identical to the above except it does not contain the hydrophobic silicone component.
