A reduced-pressure, wound closure system is presented that generates a closing force on a surface wound and optionally provides reduced pressure to a body cavity or tissue site. The sealed contracting member, when placed under reduced pressure, generates the closing force. One illustrative system includes a first attachment member and a second attachment member, a sealed contracting member coupled to the first attachment member and the second attachment member, and wherein the closing force is generated between the first attachment member and the second attachment member when reduced pressure is supplied to the sealed contracting member. Other systems and methods are presented.

1. A reduced-pressure, wound-closure system for providing a closing force to a surface wound on a patient, the reduced-pressure, wound-closure system comprising: a plurality of attachment members for releasably attaching to the patient's epidermis proximate an edge of the surface wound, wherein each of the plurality of attachment members further comprises an attachment device;a circumferential wall coupled to the plurality of attachment members, the circumferential wall for disposing proximate the surface wound;a sealed contracting member coupled to at least a portion of the circumferential wall and configured to contract under reduced pressure to move the circumferential wall, the sealed contracting member pneumatically sealed from the surface wound;a reduced-pressure source fluidly coupled to the sealed contracting member and configured to deliver a reduced pressure to the sealed contracting member; andwherein the closing force is developed when the reduced pressure is supplied by the reduced-pressure source to the sealed contracting member. 2. The reduced-pressure, wound-closure system of claim 1 wherein the circumferential wall comprises polypropylene. 3. The reduced-pressure, wound-closure system of claim 1 wherein the circumferential wall comprises rigid silicone. 4. The reduced-pressure, wound-closure system of claim 1 wherein each attachment member of the plurality of attachment members comprises a first base member and the attachment device comprises adhesive. 5. The reduced-pressure, wound-closure system of claim 1 wherein the sealed contracting member comprises: a contracting manifold material having a first side and a second, inward-facing side, and a peripheral edge;a first sealing member disposed proximate the first side of the contracting manifold material;a second sealing member disposed proximate the second, inward-facing side of the contracting manifold material;a peripheral sealing member disposed proximate the peripheral edge of the contracting manifold material; andwherein the first sealing member, second sealing member, and peripheral sealing member are configured to pneumatically seal the contracting manifold material. 6. The reduced-pressure, wound-closure system of claim 5 wherein the peripheral sealing member comprises a third sealing member. 7. The reduced-pressure, wound-closure system of claim 5 wherein the peripheral scaling member comprises a wall. 8. The reduced-pressure, wound-closure system of claim 5 wherein each of the plurality of attachment members comprises: a first base member having a first side and a second, inward-facing side;a first wall coupled to the first base member; andwherein the attachment device comprises an adhesive that is coupled to the second, inward-facing side of the first base member. 9. The reduced-pressure, wound-closure system of claim 1, wherein each of the plurality of attachment members comprises a base coupled to the circumferential wall. 10. The reduced-pressure, wound-closure system of claim 1, wherein the attachment device comprises an adhesive. 11. The reduced-pressure, wound-closure system of claim 1, wherein the attachment device comprises a bond. 12. The reduced-pressure, wound-closure system of claim 1, wherein the attachment device comprises a suture. 13. The reduced-pressure, wound-closure system of claim 1, wherein the circumferential wall comprises a semi-rigid material configured to flex when the sealed contracting member is contracted. 14. A reduced-pressure, wound-closure system for providing a closing force to a surface wound on a patient, the reduced-pressure, wound-closure system comprising: a plurality of attachment members coupled to the patient's epidermis in a spaced relationship, wherein each of the plurality of attachment members comprises a base and an attachment device;a closed wall that defines an interior space;a sealed contracting member disposed within the interior space and coupled in at least two locations to the closed wall, the sealed contacting member pneumatically sealed from the surface wound and having a contracted position and a non-contracted position, wherein the closed wall is formed from a semi-rigid material that flexes when the sealed contracting member transitions from the non-contracted position to the contracted position; anda reduced-pressure interface coupled to the closed wall, wherein the reduced-pressure interface is fluidly coupled to the sealed contracting member for delivering reduced pressure to the sealed contracting member. 15. The reduced-pressure, wound-closure system of claim 14, further comprising a reduced-pressure subsystem for supplying reduced pressure, wherein the reduced-pressure subsystem is fluidly coupled to the reduced-pressure interface. 16. The reduced-pressure, wound-closure system of claim 14, having an aperture formed through the sealed contracting member.
