Glass-based particles of a biocompatible material which comprises 40 to about 80 wt % borate (B.sub.2O.sub.3) intermixed into a carrier which is an ointment, cream, or surgical glue.

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.

A wound recovery garment includes a multilayer fabric. The multilayer fabric comprises at least first layer including opalescent microparticles, a second layer for absorbing and holding moisture, and a third layer adjacent to tissue or a wound enabled to absorb moisture and provide microsensor beads to an immediate area to detect a state of the tissue or wound. The first layer is formed from compressive, elastic material that supplies compression forces to tissue. The first layer is an elastic exterior layer incorporating the opalescent microparticles and is visible to outside viewers. The microparticles change color according to a stretch factor of the first layer indicating a pressure reading to the viewer.

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.

Adhesive wound dressing that comprises an absorbent matrix (A) adhering to the central portion of a polyurethane backing (B) having an adhesive layer for the skin, said matrix (A) comprising: a. a breathable and porous polyethylene film at the end designed to come into contact with the wound; b. an absorbent layer made of non-woven fabric adjacent to film a), said absorbent layer consisting of: i. 60-65% viscose ii. 25-30% polyester iii. 5-15% polypropylene; c. a layer of polyethylene inserted between layer b) and a layer d. of hydrophobic polystyrene, the latter being in contact with the central portion of polyurethane backing (B); wherein matrix (A) is impregnated with a solution of one or more polysaccharides or the salts thereof.

This invention provides compositions and methods of treating subjects with wounds. Compositions include dressings comprising a sheet and an adhesive, wherein the adhesive is adhered to the sheet, and wherein the sheet has channels. In some embodiments, the channels comprise two different classes of channels (e.g. liquid channels and air channels). These dressing can be applied to various kinds of skin injuries and remain affixed, protecting the injury from contaminants and at the same time, allowing exchange of exudates on the proximal (injury) side to the distal side and exchange of topical agents applied from the distal side of the dressing to the wound while also allowing exchange of gasses from the injury to the air and air to the wound.

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.
