REDUCED-PRESSURE, WOUND-CLOSURE AND TREATMENT SYSTEMS AND METHODS
First Claim
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 first attachment member for releasably attaching to a first portion of the patient'"'"'s epidermis proximate an edge of the surface wound;
a second attachment member for releasably attaching to a second portion of the patient'"'"'s epidermis proximate the edge of the surface wound, wherein the first attachment member is spaced from the second attachment member;
a sealed contracting member coupled to the first attachment member and the second attachment member and operable to contract under reduced pressure; and
wherein a closing force is developed between the first attachment member and the second attachment member when reduced pressure is supplied to the sealed contracting member.

Abstract
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.
