Methods and apparatuses are disclosed relating to the creation and use of bespoke wound fillers and other wound treatment apparatuses. Some embodiments provide for the creation of bespoke wound fillers based on characteristics of a wound. Certain embodiments also include the use of bespoke wound fillers in combination with negative pressure to treat a wound.

One or more embodiments include antimicrobial bandages with nanostructures, formation thereof, and usage thereof to facilitate wound healing. In one embodiment, a bandage apparatus that facilitates healing a wound is provided. The bandage apparatus includes a substrate having an attachment mechanism that facilitates removably attaching the substrate to a part of a body having the wound. The bandage apparatus also includes a nanostructure film provided on a surface of the substrate and configured to contact the wound when the substrate is attached to the part of the body having the wound, wherein the nanostructure film includes a plurality of nanostructures.

A wound dressing (10) for covering a wound, including an absorbent layer (12) with an upper side (14) and a lower side (18), the upper side being coated with a protective layer (16). At least one cut (26) and at least one perforated dividing line (28) is incorporated into the absorbent layer (12) to form at least one segment (30, 32, 34, 36), which can be separated from the absorbent layer (12) without tools. An adhesive section (40) originates from the protective layer (16) for covering the at least one cut (26) and the at least one perforated dividing line (28).

A mechanical wound therapy (MWT) system includes a connection for a vacuum source, which is routed through an airtight covering to a porous material positioned over the wound. The porous material may be a tubing network interspaced by a netting material constructed of biologically inert or bioabsorbable material. Alternatively, the porous material may be a layered unified dressing in which layers of mesh, netting or thin perforated film are separated and fixedly attached to functional elements of the dressing (e.g., irrigation tubing) or spacers. The vacuum and irrigation systems may be completely separated. An airtight sealing layer or foldable adhesive sealing layer may seal the dressing and facilitate sealing the dressing to the wound margins. Additional modular devices such as a wound approximating system, positive pressure bladders and adjuvant therapy modules as well as enhanced monitoring technology can be added to synergistically increase the capabilities of each dressing.

The invention relates to a flat wound care article having an essentially polygonal or ellipsoid base surface and at least one recess arranged on one side.

A microstructured hemostat comprising multiple layers of microstructure, each layer characterized by one or more length scales, is described. Microstructured hemostats of the present invention, can reduce the time for blood coagulation, control the morphology of the coagulation, and provide a novel diagnostic platform for evaluation of coagulation function from a morphological perspective.

The device (10, 36, 38, 42, 68) applies a negative pressure to an endoluminal surface in the body of a patient to facilitate healing of a wound in the endoluminal surface. The device comprises a flexible porous element (14) with a peripheral outer face (32) for contact with the wound, the outer face being defined between opposite proximal and distal ends of the porous element. A suction tube (30) for being connected to a suction source externally of the patient's body is provided in fluid communication with the porous element to apply a negative pressure to the wound via the outer face (32) of the porous element (14) upon operation of the suction source. The porous element (14) has at least one through passageway (16) extending from its proximal end to its distal end for passage of bodily substances of the patient through the porous element. The device can also include a drainage tube (22) for collection and drainage of the bodily substances from the patient, wherein the drainage tube is received in the through passageway of the porous element. The device is particularly suitable for assisted healing of anastomotic wounds but its use is not limited thereto.

A toroidal compression bandage includes: a soft fibrous material, defined by an absorbency of a predetermined amount; a compression bandage form comprised of soft fibrous absorbent material in a rolled, wrapped form and of a shape defined by a circle revolved in three-dimensional space about a circular axis coplanar with the circle, wherein the axis of revolution does not touch the rotated circle, to define a torus ring compression bandage; an aperture defined within a center area of the torus ring compression bandage as it is formed, the aperture having a predetermined diameter and configured for placement directly over a trauma wound to avoid contact with the trauma wound; and a compression surface defined on an underside of the torus ring compression bandage, the compression surface configured for circumferential placement around the trauma wound to avoid direct contact of the trauma wound, and for absorption placement around the trauma wound.

The invention relates to a device for treating blood flow in an internal wound, including a handling member connected to a series of successively narrower tubes, each tube including a liquid-expandable article. The tubes can be pivotably connected to each other, allowing the tubes to conform to the contours of the wound, or fixed together. The tubes can be encased in a liquid-soluble layer that keeps the liquid-expandable article sequestered from liquids.

The stepwise-tapering profile of the device allows for its insertion into the internal wound with little or no resistance until fully seated. Upon encountering liquids within the wound, the liquid-soluble layer can dissolve to expose the liquid-expandable article. When exposed to the wound liquids, the liquid-expandable element can expand in volume, providing compressive pressure against internal wound surfaces and minimizing blood loss.

The tubes and the liquid-expandable element can include therapeutic agents for treating the wound.
