An apparatus and method for aspirating, irrigating and/or cleansing wounds is provided. The apparatus and method include one or more of the following: simultaneous aspiration and irrigation of the wound, supplying of thermal energy to fluid circulated through the wound; supplying physiologically active agents to the wound; a biodegradable scaffold in contact with the wound bed; and application of stress or flow stress to the wound bed.

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.

A wound care bandage for treating a wound is provided. The bandage includes an SIS layer to be placed on the wound surface and a cover to be placed over the wound. The bandage further includes a structure to provide a vacuum space. A method for promoting wound healing is further provided. The method includes applying the above-mentioned wound care bandage to the wound and creating a vacuum in the vacuum space to draw blood controllably from the wound into the SIS layer.

An apparatus for cleansing wounds, in which wound exudate is removed from a wound bed and selectively cleansed and returned to the wound. The cleansing means removes materials deleterious to wound healing, and the cleansed fluid, still containing materials that are beneficial in promoting wound healing, is returned to the wound bed. The associated wound dressing and cleansing means are conformable to the wound, and may have irrigant fluid circulated from a reservoir by a device for moving fluid through a flow path which passes through the dressing and a means for fluid cleansing and back to the dressing.

The invention relates to a wound care article relates having at least one flat layer consisting of a woven fabric or nonwoven comprising superabsorbent fibers and superabsorbent particles.

Embodiments of a negative pressure wound therapy systems and methods for operating the systems are disclosed. In some embodiments, a system includes a pump assembly, canister, and a wound dressing configured to be positioned over a wound. The pump assembly, canister, and the wound dressing can be fluidically connected to facilitate delivery of negative pressure to a wound. The pump assembly can present graphical user interface screens for controlling and monitoring delivery of negative pressure. The system can be configured to efficiently deliver negative pressure and to detect and indicate presence of certain conditions, such as low pressure, high pressure, leak, canister full, and the like. Monitoring and detection of operating condition can be performed by measuring one or more operational parameters, such as pressure, flow rate, and the like.

An apparatus for cleansing wounds, in which wound exudate is removed from a wound bed and selectively cleansed and returned to the wound. The cleansing means removes materials deleterious to wound healing, and the cleansed fluid, still containing materials that are beneficial in promoting wound healing, is returned to the wound bed. The associated wound dressing and cleansing means are conformable to the wound, and may have irrigant fluid circulated from a reservoir by a device for moving fluid through a flow path which passes through the dressing and a means for fluid cleansing and back to the dressing.

An apparatus for filling a wound can include an array of at least four truncated ellipsoids interconnected to define at least one fluid path through, for example perpendicular to, the array. The longest principal axis of each ellipsoid may be perpendicular to the array. Each truncated ellipsoid may be a spheroid and/or may include an approximately elliptical contact surface at each contact surface between two interconnected ellipsoids. Each fluid pathway may have four continuously-curved concave sides and may have a parallelogram-shaped cross-section with continuously-curved concave edges. A dressing may include the apparatus, a dressing layer coupled to the apparatus, a backing layer disposed over a surface of the dressing layer opposite the apparatus, and an attachment device disposed on at least a margin of the backing layer. Methods of treating various tissue sites using the apparatus or dressing with negative-pressure therapy are also disclosed.

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 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.
