The V.A.C.® (Vacuum Assisted Closure™) assists in wound closure by applying localized negative (sub-atmospheric) pressure to help promote wound healing. Vacuum pressure is applied to a special dressing positioned in the wound cavity or over a flap or graft. This pressure-distributing wound packing helps remove fluids from the wound and promote the normal healing process.
V.A.C. Therapy uses an open-cell reticulated foam that can be cut to the shape of the wound(s), or can be placed side by side or layered to treat very large wounds. A tube embedded in the foam allows the application of vacuum pressure for the removal of excess wound fluid. The dressing and distal evacuation tube are covered by a transparent, occlusive drape that provides a seal which allows the application of vacuum pressure to the system.
