A negative pressure therapy unit is disclosed that is designed for healing internal wounds under the application of negative pressure. A plurality of tubes sequentially movable relative to one another are used to locate a filler material inside the organ. The tubes cover the filler material to avoid contact with the organ and filler material. A pressure tube passes internally to the plurality of tubes and communicates with the filler material. The filler material is in a compressed state between at least one of the plurality of tubes and the pressure tube. Translation of one of the plurality of tubes selectively exposes the filler material and permits the filler material to expand into the wound. The filler material is interchangeable on the wound and selectively on the pressure tube.

A system and method for development of personalized implantable scaffolds for wound healing. The process involves 3D scanning or 3D imaging of wounds to create 3D images which are post processed using CAD modeling software to generate 3D models of the wounds for integration with 3D, 4D, 5D, or 6D printers. Using biocompatible materials, scaffolds specific to the wounds create a personalized fit. The scaffolds can be integrated with wound healing components, cells and sensors for real-time monitoring of the local environment to promote healing. The developed personalized scaffolds for wounds have great potential to significantly reduce healthcare costs and patient treatment time.

A porous wound dressing for use in negative-pressure therapy is proposed. The wound dressing has an outer edge which defines a substantially oval or rectangular outer shape of the wound dressing with a major axis and a minor axis. The wound dressing has one or more incisions or perforations which together form one or more arc-shaped lines and serve for cutting the wound dressing to size in order to adapt the wound dressing to the shape and/or size of a wound. The one or more arc-shaped lines each extend asymmetrically with respect to the major axis and/or to the minor axis and each enclose, together with a portion of the outer edge, a segment of the wound dressing that is designed for separation from the wound dressing.

A dressing or wound filler comprising a laminate structure of materials. In one example embodiment, a dressing may include a first layer comprising a first film, a second layer adjacent to the first layer and comprising a foam, and a third layer comprising a second film. The first layer and the second layer may further include a plurality of perforations or fenestrations. The third layer may include a plurality of raised features. The perforations or fenestrations of the first and second layers may be positioned or aligned with the raised features of the third layer so as to facilitate tearing of the dressing for sizing and application purposes. In some embodiments, the first layer may comprise a polyurethane film, the second layer may comprise a polyurethane foam, and the third layer may comprise an additional polyurethane film.

Some embodiments of the present disclosure relate to a wound packing material, suitable for use in negative pressure wound therapy, comprising a body of a porous material, the body comprising frangible regions defining a plurality of portions, the frangible regions allowing the portions to be selectively removed from the body. The wound packing material can be shaped to partially or fully surround a secondary wound packing member, such as a stabilizing structure. Some embodiments further relate to methods of manufacturing the wound packing material, and to methods of its use.

Some arrangements disclosed herein relate to devices and methods for treating a wound, comprising applying negative pressure to the wound through a cover applied over a wound, monitoring the internal pressure in the wound, and controlling the closure of the wound by controlling the amount that a wound packing material positioned under the cover collapses within the wound based on the monitored internal pressure. The wound packing material collapse can be controlled to ensure that the monitored internal pressure does not exceed a threshold value. Additionally, some embodiments or arrangements disclosed herein relate to a visualization element to visualize a location of a wound surface. The visualization element can comprise a radiopaque member that is configured to be positioned on or adjacent to a surface of an open wound.

Wound pads for use, e.g., as cavity wound fillers, having at least one incomplete cut being made of a plurality of cut segments and a plurality of connection regions are described. The wound pads can be useful in negative pressure would therapy systems and kits.

A dressing or wound filler comprising a laminate structure of film materials. In one example embodiment, a dressing may include a first layer comprising a first film, a second layer adjacent to the first layer and comprising a second film, and a third layer comprising a material having closed cells. The first layer may further include a plurality of fluid restrictions. The second layer may include blisters and apertures to allow fluid transfer through the second film. The third layer may include closed cells and apertures between the closed cells to allow fluid transfer through the third layer. The dressing may further include a fourth layer adjacent to the third layer opposite the second layer, which may include a fourth film having blisters and apertures. The dressing may also include a fifth layer, which may be adjacent to the fourth layer opposite the third layer. The fifth layer may include a film and a second plurality of fluid restrictions.
