Open-cavity, reduced-pressure treatment devices and systems

A method of manufacturing a reduced-pressure treatment device for use in a body cavity of a patient, the method comprising:

• forming a plurality of encapsulated leg members, each encapsulated leg member having a longitudinal length and an interior portion with a leg manifold member;
• forming a plurality of fenestrations on the encapsulated leg members, the fenestrations positioned along the longitudinal length of the encapsulated leg members and operable to allow fluid flow into the interior portion of the encapsulated leg members;
• forming a central connection member having a connection manifold member;
• and
• coupling the central connection member to the plurality of encapsulated leg members, wherein each leg manifold member is in fluid communication with the connection manifold member.

A method of manufacturing a reduced-pressure treatment device for use in a body cavity of a patient, the method comprising:

• forming a plurality of encapsulated leg members, each encapsulated leg member having a longitudinal length and an interior portion with a leg manifold member;
• providing a non-adherent drape, wherein the non-adherent drape forms at least a portion of the encapsulated leg members;
• forming a plurality of fenestrations on the encapsulated leg members, the fenestrations positioned along the longitudinal length of the encapsulated leg members and operable to allow fluid flow into the interior portion of the encapsulated leg members;
• forming a central connection member having a connection manifold member;
• and
• coupling the central connection member to the plurality of encapsulated leg members, wherein each leg manifold member is in fluid communication with the connection manifold member.

A method of manufacturing a reduced-pressure treatment device for use in treating a tissue site in a body cavity of a patient, the method comprising:

• providing a first non-adherent drape;
• providing a second non-adherent drape;
• positioning a manifold unit as a layer between the first non-adherent drape and the second non-adherent drape, the manifold unit having a plurality of leg manifold members and a connection manifold member;
• and
• coupling the first non-adherent drape to the second non-adherent drape, thereby providing a plurality of encapsulated leg members in fluid communication with a central connection member, each encapsulated leg member having a longitudinal length.
