An apparatus for cleansing wounds in which irrigant fluid from a reservoir connected to a conformable wound dressing and wound exudate from the dressing are recirculated 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 cleansing means (which may be a single-phase, e.g. microfiltration, system or a two-phase, e.g. dialytic system) removes materials deleterious to wound healing, and the cleansed fluid, still containing mate rials that are beneficial in promoting wound healing, is returned to the wound bed. The dressing and a method of treatment using the apparatus.

1. A system for applying negative pressure on a wound, the system comprising: a device including a pump configured to provide negative pressure on the wound via a first vacuum line, wherein the device weighs less than 0.5 kg;a dressing material for sealably covering the wound, the dressing material comprising a boss, the first vacuum line extending between the device and the boss of the dressing material to provide negative pressure to the wound sealably covered by the dressing material; andan injectable foam configured to be located within the wound below the dressing material, wherein the injectable foam is configured to be introduced through an inlet line and substantially conform to a shape of the wound, wherein the first vacuum line and the inlet line are separate lines configured to be in fluid communication with the wound through the boss of the dressing material. 2. A system according to claim 1, wherein the device is portable. 3. A system according to claim 1, wherein the device includes a waste reservoir. 4. A system according to claim 1, wherein the pump comprises a peristaltic pump. 5. A system according to claim 1, wherein the pump is selected from a group consisting of a shuttle pump, diaphragm pump, piston pump, centrifugal pump, flexible impeller pump, progressing cavity pump, rotary vane pump, and vacuum pump with a pressure regulator. 6. A system according to claim 1, wherein the pump includes a check valve configured to control direction of a fluid flow. 7. A system according to claim 1, wherein the dressing material comprises a manifold connected to the pump, the manifold comprising a plurality of tubes configured to collect fluid from the wound. 8. A system for applying negative pressure on a wound, the system comprising: a device including a structure configured to provide negative pressure on the wound via a first vacuum line;a dressing material configured to sealably cover the wound, the dressing material comprising a boss, the first vacuum line configured to extend between the device and the boss of the dressing material to provide negative pressure to the wound sealably covered by the dressing material; andan injectable foam configured to be located within the wound below the dressing material, the injectable foam configured to be introduced through an inlet line and exposed to the negative pressure provided by the device, wherein the injectable foam comprises an aerosol foam that has a set state the injectable foam is capable of substantially conforming to a shape of the wound;wherein the first vacuum line and the inlet line are separate lines configured to be in fluid communication with the wound through the boss of the dressing material. 9. A system according to claim 8, wherein the device includes a waste reservoir. 10. A system according to claim 8, wherein the structure within the device configured to provide negative pressure on the wound includes a peristaltic pump. 11. A system according to claim 8, wherein the structure within the device configured to provide negative pressure on the wound is selected from a group consisting of a shuttle pump, diaphragm pump, piston pump, centrifugal pump, flexible impeller pump, progressing cavity pump, rotary vane pump, and vacuum pump with a pressure regulator. 12. A system according to claim 8, further comprising a waste reservoir configured to be connected to the device, the waste reservoir configured to store exudate removed by the negative pressure applied to the wound. 13. A system for applying negative pressure on a wound, the system comprising: a pump configured to provide negative pressure on the wound via a first vacuum line;a dressing material configured to sealably cover the wound, the dressing material comprising a boss, the first vacuum line configured to extend between the device and the boss of the dressing material to provide negative pressure to the wound; andan injectable foam configured to be introduced through an inlet line and placed within the wound, wherein the injectable foam is capable of substantially conforming to a shape of the wound, wherein the first vacuum line and the inlet line are separate lines configured to be in fluid communication with the wound through the boss of the dressing material. 14. A system according to claim 13, wherein the pump weighs less than 0.5 kg. 15. A system according to claim 13, wherein the pump is portable. 16. A system according to claim 13, wherein the pump comprises a peristaltic pump. 17. A system according to claim 13, further comprising a waste reservoir connected to the pump for storing exudate obtained by the applied pressure on the wound. 18. A system according to claim 13, wherein the pump is selected from a group consisting of a shuttle pump, diaphragm pump, piston pump, centrifugal pump, flexible impeller pump, progressing cavity pump, rotary vane pump, and vacuum pump with a pressure regulator. 19. A system according to claim 13, wherein the pump includes a check valve configured to control direction of a fluid flow. 20. A system according to claim 13, wherein the dressing material comprises a manifold connected to the pump, the manifold comprising a plurality of tubes configured to collect fluid from the wound.
