A dressing system is disclosed which has a sponge and a near infrared spectroscopy sensor positioned adjacent to the sponge for monitoring oxygenation levels of tissue adjacent to the sponge. The dressing system may further include a tube coupled to the sponge for removing fluid from the sponge. The dressing system comprises: a sponge; and a tensioning system coupled to the sponge. The tensioning system further comprises a central longitudinal member coupled to the sponge; and at least one tensioning member coupled to the central longitudinal member. A sequential compression system comprises: an envelope sleeve dressing; and a bladder that is both expandable and retractable. A tissue filler system is also described and includes a plurality of tubes; wherein each of the plurality of tubes further comprises apertures; and a pump coupled to at least one of the tubes which obviates the need for any sponge or wound screen.

A negative pressure wound treatment system comprising a bandage portion and a negative pressure portion. The bandage portion includes a dressing portion in contact with a wound and a sealing layer positioned in contact with the dressing portion. The sealing layer includes an adhesive creating a seal around the wound. The negative pressure portion is in fluid communication with the bandage portion and includes a first valve and a second valve. The first valve is in fluid communication with the bandage portion and the negative pressure portion. The second valve is in fluid communication with the negative pressure portion and the surrounding environment. The negative pressure wound treatment system is configured to provide negative pressure to an area sealed by the bandage portion upon the actuation of the negative pressure portion. The negative pressure portion is configured to be actuated by compressing the negative pressure portion while walking.

A dressing assembly for use with a reduced pressure treatment system, the dressing assembly develops a directed force under reduced pressure. The directed force may be a radial force or a closing force. The dressing assembly includes a shaped dressing bolster having a shaped extremity that is operable to evenly deliver the radial force and to distribute reduced pressure. Numerous shapes may be used for the shaped extremity. The dressing assembly may further include an over-drape to assist in creating a seal over the shaped dressing bolster and against a portion of a patient's epidermis.

A wound therapy device and a kit for same with a housing material, a gasket disposed around at least a portion of the housing material, a non-woven absorption material, and a port. The gasket is sized and configured such that at least a first portion of the gasket will be adhered to a second portion of the gasket upon a folding of the housing material. A method of using a wound therapy device.

A tissue interface, suitable for use in an abdominal cavity, may comprise a liquid-impermeable layer having manifolding bubbles on at least a first surface. In some embodiments, a pattern of break-lines, without bubbles, may separate the plurality of bubbles into zones. For example, each break-line may be wider than the gap spacing between bubbles within adjacent zones on either side of the break-line. In some embodiments, the configuration of the pattern of break-lines may impact fluid flow rate across the liquid-impermeable layer during negative-pressure therapy. Users may be able to select a tissue interface with a break-line pattern corresponding to a desired fluid flow rate.

In some embodiments, a negative pressure wound closure system and methods for using such a system are described. Certain disclosed embodiments facilitate closure of the wound by preferentially contracting to exert force on the tissue. Some embodiments may utilize a collapsible structure with a plurality of cells.

A method and apparatus are provided for treating cardiac tissue to modulate ischemic heart tissue with topical sub-atmospheric pressure to minimize cell death and damage.

A see-through dressing assembly is presented for use with a reduced-pressure system for treating a wound on a patient using reduced pressure that allows visual observation of the wound during treatment. The dressing assembly includes a bolster for providing a directed force when under reduced pressure, a sealing member for covering the bolster and providing a seal over the bolster and a patient's epidermis, and wherein the bolster and sealing member are formed from see-through materials sufficient to allow perception of color from a point external to the system. Other systems, dressings, and methods are presented.

Devices and methods for wound treatment are disclosed. A chamber may define a treatment space having an interior engineered surface including a plurality of structures configured to provide pathways for the distribution of negative pressure and to exert mechanical stress on a wound. One or more tubes may be in fluid communication with the treatment space to facilitate the application of negative pressure, the introduction of therapeutic agents, and the removal of wound material. Therapeutic agents may be formulated with a gel, for example, a hydrogel, a hydrocolloid, alginate, methyl cellulose, gelatin or any other gels for sustained-release and enhanced usability. A wound fluid collection device including an absorbable material may interface with the wound treatment device to facilitate the collection and disposal of wound material.

A protective and permissive healing medical device comprising a sealable enclosure made from a flexible and see-though dressing, coupled with a scaffold structure capable of separating portions of the inner surface of the sealable enclosure from the outer portions of an extremity sealed inside the device, a plurality of ports for delivering materials into and extracting mediums from the sealable enclosure consistent with a therapeutic environment for the injury within the device, and a plurality of digit receiving portions facilitating individually articulable movement during healing within the sealable enclosure.
