Abstract

A modular, reduced-pressure, wound-closure system for providing a closing force on a surface would includes a flexible strap operable to be formed into a closed loop inbound and around the surface wound and a plurality of modular closing members coupled to the flexible strap. A reduced-pressure source is fluidly coupled to the plurality of modular closing members. The modular closing members are operable to generate a closing force on the surface wound. A portion of the modular closing members are releasably attached to the patient's epidermis proximate the surface wound and another portion are attached to the flexible strap. A reduced pressure from the reduced-pressure source is delivered to each modular closing member to generate the closing force on the surface wound. Methods and other systems are presented.

Claims (31)

1. A method of treating a wound, the method comprising:

placing a loop of closing members on a surface proximate to the wound, wherein the loop is placed within a perimeter of the wound, and wherein the closing members are spaced around the wound on the surface;

securing an end of each closing member to the surface; and

contracting the closing members with reduced pressure applied to contracting members sealed within each closing member such that each closing member provides a closing force on the wound.

2. The method of claim 1 , wherein the surface is an epidermis.

3. The method of claim 1 , wherein the surface is a sealing member applied to an epidermis proximate to the wound.

4. The method of claim 1 , wherein placing the loop of closing members on the surface comprises sizing the loop based on a circumference of the wound.

5. The method of claim 1 , wherein placing the loop of closing members on the surface comprises:

determining a number of closing members to be placed based on a size of the wound; and

sizing the loop based on the number of closing members.

6. The method of claim 1 , wherein placing the loop of closing members on the surface comprises:

determining a number of closing members to be placed based on a size of the wound;

coupling the determined number of the closing members to a spacing member;

sizing the spacing member; and

forming the loop from the spacing member with the determined number of the closing members.

7. The method of claim 1 , wherein each of the contracting members comprises a porous foam.

8. A method of treating a tissue site, the method comprising:

placing a non-adherent envelope containing a manifold member on abdominal contents;

sealing a wound in the epidermis with a sealing member;

placing a loop of closing members on a surface proximate to the wound in the epidermis, wherein the loop is placed within a perimeter of the wound, and wherein the closing members are spaced around the wound on the surface;

attaching an end of each closing member to the surface;

distributing reduced pressure to an abdominal cavity through the manifold member on the abdominal cavity;

contracting the closing members with a reduced pressure applied to contracting members sealed within each closing member such that each closing member provides a closing force on the wound.

9. The method of claim 8 , further comprising:

placing a second manifold member adjacent to the non-adherent envelope in the abdominal cavity; and

distributing the reduced pressure through the second manifold member.

10. The method of claim 8 , further comprising:

placing a second manifold member adjacent to the non-adherent envelope and proximate to subdermal tissue in the abdominal cavity; and

distributing the reduced pressure through the second manifold member.

11. The method of claim 8 , wherein the surface is the epidermis.

12. The method of claim 8 , wherein the surface is the sealing member.
