Embodiments of a negative pressure wound closure system and methods for using such a system are described. Certain disclosed embodiments facilitate closure of a wound by preferentially exerting a negative pressure on tissue. Some embodiments may utilize a collapsible sheet with a plurality of cells.

The present invention relates to a negative pressure wound closure system and methods for using such a system. Preferred embodiments of the invention facilitate closure of the wound by preferentially contracting to provide for movement of the tissue. Preferred embodiments can utilize tissue securing portions that aid in securing the invention within a wound.

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.

Described are wound pads for use, e.g., as cavity wound fillers, having shapes with rounded corners, the projection on an X-Y plane of at least one corner having a curvature distinct from that of the projection of the other corners. Negative pressure systems and kits that includes such wound pads, and methods of using such wound pads are also described.

A treatment system for debriding a treatment area of a tissue site and applying negative pressure is disclosed. In some embodiments, the treatment system may include an ultrasonic bubble generator fluidly coupled to a negative-pressure source, fluid source, and a dressing. Fluid may be drawn from the fluid source to the ultrasonic bubble generator, whereby micro-bubbles and ultrasonic waves may be generated in the fluid before the fluid is instilled to the dressing.

The present invention relates 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 invention further relates to methods of manufacturing the wound packing material, and to methods of its use.

Embodiments disclosed herein relate to systems, devices and methods for monitoring dimensional changes in medical devices attached to or implanted in the body, such as wound fillers. Disclosed embodiments may facilitate measuring the degree of wound closure by incorporating conductive elements into the wound filler. In some embodiments, the conductive elements may be conductive filler, a flexible conductive element, or an arrangement of discrete non-flexible conductive elements. The density of conductive material in an area or volume of the wound filler upon wound closure may be detected by a detection device that assesses the local dielectric constant of the wound filler, such as through use of a capacitive plate, or by a detection device that measures the resonant frequency of a conductive element.

A device designed to be packed into a wound that will expand to fill the voids of the wound to control bleeding is provided. The device is comprised of two or more individual pouches, linked together, and filled with an expandable material that will swell upon absorption of blood through the pouch walls.
