Abstract: A wound treatment system can include control circuitry configured to provide a drive signal to a wound dressing. The wound dressing can be configured to perform wound treatment based upon the drive signal. Prior to performing the wound treatment, the control circuitry can be paired with the wound dressing. The wound dressing can be configured to function only when connected to particular control circuitry after pairing of the wound dressing and the control circuitry. Further, based on pairing the wound dressing and the control circuitry, a timer can be initialized such that the wound dressing can be configured to function prior to the timer reaching a lifetime threshold and the control circuitry can be configured to disable the wound dressing, via a fuse, upon the timer reaching the lifetime threshold.

Abstract: A negative pressure wound closure system and methods for using such a system are described. Preferred embodiments of the invention facilitate closure of the wound by utilizing a stabilizing structure that preferentially contracts to provide for movement of the tissue. Some embodiments may utilize a protective layer, such as a mesh or net layer, attached to a top surface of the stabilizing structure. The protective layer prevents a drape positioned over the stabilizing structure from being drawn into cells of the stabilizing structure, and permits visualization of the collapse of the cells.

Abstract: Disclosed herein are several embodiments of a wound treatment apparatus employing a wound dressing for negative pressure wound therapy and methods of using the same. Some embodiments are directed to improved wound dressing to be applied to a wound site, for example a wound dressing including a three-dimensional filter element, and methods of using the same.

Preferred embodiments of the invention facilitate closure of the wound by preferentially contracting to provide for movement of the tissue. Some embodiments may include wound closure devices built from smaller units that are modular, assemble-able and/or customizable.

Abstract: Disclosed embodiments relate to a wound dressing which can generate nitric oxide. The wound dressing may include a cover layer, an activator layer such as an acid providing layer and nitric oxide source layer, such as a nitrite providing layer. The activator layer may include acidic groups and may be hydrogel, xerogel, or other suitable material. The activator layer may include a copolymer of monomers with one or more covalently linked multifunctional groups.

Abstract: Disclosed embodiments relate to apparatuses and methods for wound treatment with ultrasound. In certain embodiments, therapeutic ultrasound wound treatment apparatus includes a wound dressing configured to be positioned over a wound to provide a substantially fluid impermeable seal over the wound and a transducer to deliver therapeutic ultrasound to tissue. The therapeutic ultrasound wound treatment apparatus may further include a wound contact layer configured to be positioned in contact with the wound, a transmission layer positioned above the wound contact layer, an absorbent layer positioned above the transmission layer and configured to absorb wound fluid, and a backing layer positioned above the absorbent layer and including an orifice. Also disclosed are multiple parameters for the therapeutic ultrasound signal.

The wound dressing may include a cover layer, an activator layer such as an acid providing layer and nitric oxide source layer, such as a nitrite providing layer. The activator layer may include acidic groups and may be hydrogel, xerogel, or other suitable material. The nitric oxide source layer may include a nitrite salt. Nitrite ions of the nitric oxide source layer may react with the acidic groups of the activating layer to generate nitric oxide. The activating layer may include a window at the center, and a central absorbent material may be positioned at the window. Various separating layers may also be incorporated into the dressing to control the interaction between activating layer and nitric oxide source layer.

Abstract: Disclosed embodiments relate to a wound dressing which can generate nitric oxide. The wound dressing comprises a cover layer, an acid providing layer and a nitrite providing layer. The acid providing layer comprises acidic groups and may be hydrogel or Xerogel. The nitrite providing layer comprises a nitrite salt. The wound dressing may also include other layers, one or more acquisition distribution layers or masking layers. The masking layers can at least partially prevent visualization of the layer below the masking layer. Nitrite ions of the nitrite providing layer may react with the acidic groups of the acid providing layer to generate nitric oxide. The acid providing layer further includes one or more material layers to reduce the adhesiveness of the acid providing layer. The acid providing layer can also include perforations.

Abstract: Disclosed embodiments relate to apparatuses and methods for wound treatment. In certain embodiments, a negative pressure wound therapy apparatus can include a wound dressing comprising an absorbent layer comprising a plurality of portions of absorbent material that can be physically separate from each other. In some embodiments, a wound treatment apparatus can include an absorbent layer comprising a compressed portion configured to impede the flow of fluid therethrough. In some embodiments, a wound treatment apparatus can include an absorbent layer and spacer layer positioned side by side.
