Abstract

A method of manufacturing a reduced-pressure abdominal treatment system for treating an open abdominal cavity of a patient is provided. A reduced-pressure abdominal treatment system has an open-cavity treatment device for providing reduced-pressure treatment to a patient's abdominal cavity; a deep-tissue closure device for applying a closing force on a deep-tissue wound on a patient's fascia; a surface-wound closure subsystem for providing a closing force on a surface wound on the patient's epidermis. The method of manufacturing may also include the step of providing a reduced-pressure supply subsystem.

First claim

We claim:

1. A method of manufacturing a system for treating an abdominal cavity of a patient, the method comprising the steps of:
forming an open-cavity treatment device comprising a plurality of encapsulated leg members for providing reduced-pressure treatment to a patient's abdominal cavity, wherein each of the plurality of encapsulated leg members comprises a leg manifold member disposed within an interior portion of the encapsulated leg member and is formed with fenestrations operable to allow fluid flow into the interior portion;
forming a deep-tissue closure device for applying a closing force on a deep-tissue wound on a patient's fascia and configured to be coupled to the open-cavity treatment device; and
forming a surface-wound closure subsystem for providing a closing force on a surface wound on a patient's epidermis, wherein the surface-wound closure subsystem is configured to be deployed on an external surface of the patient's epidermis.

2. The method of claim 1 further comprising the steps of providing a reduced-pressure supply subsystem and fluidly coupling the reduced-pressure supply subsystem to the open-cavity treatment device, the deep-tissue closure device, and the surface-wound closure subsystem.

3. The method of claim 1 , wherein the step of forming an open-cavity treatment device further comprises the steps of:
forming a non-adherent drape with fenestrations;
coupling the plurality of encapsulated leg members to the non-adherent drape;
forming a central connection member with a connection manifold member; and
coupling the central connection member to the non-adherent drape and to the plurality of encapsulated leg members, wherein each leg manifold member is in fluid communication with the connection manifold member.

4. The method of claim 3 wherein the step of forming a non-adherent drape comprises forming an elastomeric drape, forming fenestrations on the elastomeric drape, and placing visual indicia on the elastomeric drape that indicates various sizes that might be cut.

5. The method of claim 1 , wherein the step of forming a deep-tissue closure device comprises the steps of:
forming a contractible matrix having a first side and a second, inward-facing side, the first side formed with a plurality of apertures, and the second, inward-facing side formed with a plurality of cells, and further formed with a plurality of inter-cellular apertures, the contractible matrix for disposing proximate the deep-tissue wound;
providing a manifold member operable to distribute reduced pressure; and
providing a sealing member operable to provide a pneumatic seal over the patient's abdominal cavity.

6. The method of claim 1 , wherein the step of forming a surface-wound closure subsystem comprises the steps of:
forming a first attachment member for releasably attaching to a first portion of the patient's epidermis proximate an edge of the surface wound;
forming a second attachment member for releasably attaching to a second portion of the patient's epidermis proximate the edge of the surface wound; and
forming a sealed contracting member operable to contract when placed under reduced pressure.

7. The method of claim 1 , wherein the step of forming a surface-wound closure subsystem comprises the steps of:
forming a sealed contracting member;
forming a plurality of attachment-base members, each attachment-base member having a base and a first wall having a first end and a second end, the first end of the first wall having a first movable connection member and the second end of the first wall having a second movable connection member, each attachment-base member for releasably attaching to a portion of the patient's epidermis and for coupling to the sealed contracting member;
forming a plurality of connecting members, each connecting member having a second wall with a first end and a second end, the first end of the second wall having a third movable connection member and the second end of the second wall having a fourth movable connection member, each connecting member for moveably coupling to one of the plurality of attachment-base members;
fluidly coupling a reduced-pressure interface to the sealed contracting member, the reduced-pressure interface operable to deliver reduced pressure to the sealed contracting member; and
wherein the plurality of attachment-base members and the plurality of connecting members are operable to moveably couple to form a circumferential wall defining an interior space and wherein the sealed contracting member is to be disposed within the interior space.

8. The method of claim 1 , wherein the step of forming a surface-wound closure subsystem comprises the steps of:
forming a flexible strap operable to be formed into a closed loop; and
forming a plurality of modular closing members, wherein the step of forming a plurality of modular closing members comprises, for each of the plurality of modular closing members, the steps of:
forming an attachment member for releasably attaching to a portion of the patient's epidermis proximate an edge of the surface wound, the attachment member formed with a base and a wall,
forming a sealed contracting member having a first end and a second end, wherein the sealed contracting member is operable to contract when placed under reduced pressure,
coupling the second end of the sealed contracting member to the attachment member,
forming a connection member, the connection member operable to selectively couple to the flexible strap,
coupling the connection member to the first end of the sealed contracting member, and
forming a reduced-pressure interface fluidly coupled to the sealed contracting member for delivering reduced pressure to the sealed contracting member.

9. A method of manufacturing an abdominal treatment system, the method comprising the steps of:
forming an open-cavity treatment device for providing reduced-pressure treatment proximate a patient's abdominal contents, the open-cavity treatment device comprising a central connection member, a non-adherent drape, and a plurality of encapsulated leg members coupled to the central connection member and to the non-adherent drape, each of the plurality of encapsulated leg members having an interior portion and a leg manifold member disposed within the interior portion, and being formed with fenestrations operable to allow fluid flow into the interior portion;
forming a deep-tissue closure device adapted to be deployed proximate to the open-cavity treatment device for applying a closing force on a deep-tissue wound on a patient's fascia, the deep-tissue closure device having a contractible matrix; and
providing a reduced-pressure treatment subsystem for providing reduced pressure to the open-cavity treatment device and the deep-tissue closure device;
wherein each of the leg manifold members comprise a plurality of interconnected flow channels.

10. The method of claim 9 further comprising the step of forming a surface-wound closure subsystem for providing a closing force on a surface wound on a patient's epidermis, wherein the step of forming a surface-wound closure subsystem comprises the steps of:
forming a first attachment member for releasably attaching to a first portion of the patient's epidermis proximate an edge of the surface wound;
forming a second attachment member for releasably attaching to a second portion of the patient's epidermis proximate the edge of the surface wound; and
forming a sealed contracting member operable to contract when placed under reduced pressure.

11. The method of claim 10 further comprising the step of:
forming a third attachment member for releasably attaching to a third portion of the patient's ep
