Disclosed embodiments relate to apparatuses and methods for wound treatment with ultrasound. In certain embodiments, a 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.

Tissue treatment device

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.

Dressing for negative pressure wound therapy with filter

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 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.

Customizable wound closure device and method of use

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.

Wound closure device with protective layer and method of use

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.
