Abstract: Apparatuses, systems, and methods involve using reduced pressure to position a portion of tissue in a cutting head and cutting the tissue to debride a tissue site. A cutting head includes a debridement conduit having a distal end and a proximal end. A portion of the debridement conduit adjacent to the distal end comprises a tissue treatment area. The cutting head also includes an opening to the tissue treatment area formed at the distal end of the debridement conduit. The tissue treatment area is adapted to receive the portion of tissue through the opening under reduced pressure. The cutting head also includes a selectively moveable cutting member associated with the debridement conduit at the tissue treatment area. The cutting member is for cutting the portion of tissue from the tissue site while the portion of tissue resides in the debridement conduit. Other methods, systems, and apparatuses are disclosed.

Abstract: An open-cavity, reduced-pressure treatment device and system for treating a cavity in a patient's body, such as an abdominal cavity, is presented. In one instance, an open-cavity, reduced-pressure treatment device includes a plurality of encapsulated leg members, each having an interior portion with a leg manifold member and formed with fenestrations operable to allow fluid flow into the interior portion, and a central connection member fluidly coupled to the plurality of encapsulated leg members. The central connection member has a connection manifold member. The open-cavity, reduced-pressure treatment devices, systems, and methods allow for, among other things, removal of fluids.

Abstract: A reduced-pressure abdominal treatment system has an open-cavity treatment device for providing reduced-pressure treatment proximate a patient's abdominal contents; a deep-tissue closure device for applying a closing force on a deep-tissue wound on a patient's fascia; a surface-wound closure subsystem for providing a closing force on a surface wound on the patient's epidermis; and a reduced-pressure supply subsystem operable to develop a reduced pressure. Methods are also included.

Abstract: A reduced-pressure, deep-tissue closure device for applying a closing force on a deep tissue includes a contractible matrix that is formed with a first plurality of apertures and which has a first side and a second, inward-facing side. The contractible matrix is for disposing proximate to the deep tissue. A reduced-pressure source is fluidly coupled to the contractible matrix and operable to deliver reduced pressure to the contractible matrix. When under reduced pressure, the contractible matrix grips the deep tissue adjacent the contractible matrix and provides a closing force on the deep tissue. A system and method are also presented.
