Disclosed herein are dressings capable of filtering, capturing, and/or releasing select biological molecules from wound exudate. In one embodiment, the dressing may include a permeable, non-adherent envelope. The permeable, non-adherent envelope may enclose a composition comprising milled hydrophobic foam.

Embodiments disclosed herein are directed to negative pressure treatment systems and wound dressing systems, apparatuses, and methods that may be used for the treatment of wounds. In particular, some embodiments are directed to improved wound dressings comprising an obscuring layer that may hide fluid contained therein. Some embodiments may further comprise one or more viewing windows disposed therethrough so as to enable monitoring or examination of fluids contained therein.

The present invention relates to an adhesive patch. The adhesive patch includes a plurality of reliefs, each relief having a flat top face, and each micro channel groove defined between adjacent reliefs of the plurality of reliefs, wherein the plurality of reliefs and the micro channel groove are respectively formed on and defined the adhesive patch, and wherein a hydrogel layer is disposed on at least a portion of a bottom face of the micro channel groove and is contained in the groove. Therefore, the adhesive patch is well-adhered to a dry or wet adhered face.

A wound dressing includes a superabsorbent layer, a backing layer, and a charcoal layer. The superabsorbent layer is configured to absorb wound fluid and has a first side and a second, wound-facing side. The backing layer also has a first side and a second, wound-facing side. The backing layer is substantially impermeable to liquid and substantially permeable to vapor. The charcoal layer is positioned between the first side of the superabsorbent layer and the second, wound-facing side of the backing layer. The charcoal layer is configured to increase a moisture vapor transmission rate of the wound dressing.

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.

An article, including a network of interconnected polymeric strands; wherein each of the interconnected polymeric strands has a first surface adapted to contact a tissue site; wherein at least one of the interconnected polymeric strand has a plurality of features extending from the first surface of the interconnected polymeric strands; wherein only one of any two adjacent polymeric strands has a plurality of features extending from the first surface of the interconnected polymeric strands; and wherein at least one of the interconnected polymeric strands is non-linear; and a plurality of openings between adjacent interconnected polymeric strands.

An interface dressing (1) comprising an elastomeric matrix (5), the elastomeric matrix (5) being provided with a plurality of through-holes (6), each through-hole (6) having a contour (C) around a central axis (A), in which at least some of the plurality of through-holes (6) are arranged so as to form at least one pattern in which each through-hole (6) is adjacent to at least one other through-hole (6), the adjacent through-holes (6) having contours (C), images of which, when moved in translation in a plane perpendicular to the central axes (A) in order to merge images of said central axes (A) by means of said translational movement, do not become superposed.

A handheld device for producing electrospun fibrous mat comprises: a housing configured to be handheld by a user; a container accommodating at least one electrospinning medium; at least a nozzle in fluid communication with the container; a mechanism dispensing the medium from the container via said nozzle; an auxiliary electrode surrounding the nozzle; and a power supply providing electric potentials to the nozzle and the auxiliary electrode. The housing comprises an electrically conductive portion configured to be gripped by the user during operation. The electrically conductive portion is connected to the power supply.

A composite material is described, which is of particular use in wound treatment, and to a method for producing said composite material is also described. The composite material has a first foam layer having a first hydrophilic polyurethane foam material, and, in immediate contact therewith, a second foam layer having a second hydrophilic polyurethane foam material, which second hydrophilic foam material is different from the first hydrophilic foam material.

The present invention relates to a sterilized medical dressing for treating wounds comprised of a polymer sponge containing an antimicrobial agent and a silicon adhesive secured to the dressing surface. The dressing can be exposed initially to gamma radiation and later sterilized by ethylene oxide or alternatively it can be sterilized by ethylene oxide and later irradiated by gamma radiation. z The sponge dressing can also contain at least one biofilm reducing agent, at least one chelating agent and an ionic and non-ionic surfactant.
