A system for providing negative-pressure therapy to breast tissue is disclosed. In some embodiments, the system may include a dressing assembly shaped for placement on a breast, an absorbent pouch, and a negative-pressure source. The system may further include an additional dressing assembly for placement on a second breast. Various shapes and configurations of the breast dressing assemblies may be included in the system.

A reduced-pressure system for treating tissue, such as damaged subcutaneous tissue, includes a shaped dressing bolster for placing on the patient's epidermis and substantially sized to overlay the damaged subcutaneous tissue. The system further includes a sealing subsystem for providing a fluid seal over the shaped dressing bolster and a portion of the patient's epidermis, and a reduced-pressure subsystem for delivering a reduced pressure to the sealing subsystem. The reduced-pressure system may develop a force, which may include a vertical force that is realized at tissue site deeper than the epidermis or a closing force directed towards the incision. The shaped dressing bolster is shaped to evenly distribute the force. Other methods and systems are included.

A system for treating a linear wound on a patient has a closing dressing bolster for placing on the patient's epidermis over the linear wound, a sealing subsystem for providing a seal over the closing dressing bolster and the patient, and a reduced-pressure subsystem for delivering reduced pressure to the sealing subsystem. The sealing subsystem and reduced pressure subsystem are operable to deliver reduced pressure to the closing dressing bolster. The closing dressing bolster is operable under reduced pressure to develop a inward closing. The closing dressing bolster may include one or more closing members on each side of a center wound area to create the inward closing when under reduced pressure. A compressive force may also be developed. Other systems and methods are presented.

An apparatus for promoting circulation through a subcutaneous lymph vascular network may comprise a first manifold layer, a second manifold layer coupled to the first manifold layer, and a cover layer coupled to the second manifold layer. The first manifold may have a first stiffness, and the second manifold may have a second stiffness greater than the first stiffness. In some embodiments, the apparatus may additionally have a fluid interface configured to fluidly couple at least one of the first manifold layer and the second manifold layer to a fluid conductor through the cover layer. The fluid conductor may be coupled to or configured to be coupled to a source of negative pressure.

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 wound dressing and method of use is provided that increases healing of tissues by targeting damaged tissue at a predetermined wavelength. The device includes the use of a negative pressure bandage, a flexible light sheet, and one or more bioactive marine extracts. Light emitted from the flexible light sheet penetrates through the bandage to target damaged tissue, which accelerates the wound healing process and works synergistically with the negative pressure bandage and bioactive marine extracts such as collagen fibers, alginate, chitosan and fucoidan, or any combination thereof to accelerate healing.

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 therapy (NPWT) orthopedic device includes a base shell and a dorsal shell contoured to generally correspond to an opening of the base shell. The dorsal shell includes a proximal section and a distal section. The proximal section at least in part defines a receiving space. A NPWT system includes a pump mechanism secured in the receiving space and a wound covering situated inside of the base shell and arranged to form a sealed volume over a wound area of a user. At least one conduit forms a fluid connection between the wound covering and the pump mechanism. The pump mechanism is arranged to apply a negative pressure to the wound area through the at least one conduit.
