A modular, reduced-pressure, wound-closure system for generating a closing force on a surface wound on a patient includes a sealed contracting member, a plurality of attachment base members, and a plurality of connecting members. The combination of the plurality of attachment base members and plurality of connecting members forms a circumferential wall around the surface wound. The sealed contracting member is operable to be disposed within an interior space defined by the circumferential wall and coupled to at least of portion of the circumferential wall. When reduced pressure is provided to the sealed contracting member, the sealed contracting member contracts and the circumferential wall delivers a closing force. Other systems and methods are presented.
