1. A method of administering a reduced pressure tissue treatment to a tissue site comprising:

  • percutaneously inserting a tube through a skin tissue of a patient to place a distal end of the tube adjacent the tissue site, the tube having at least one passageway;

    positioning a balloon extending from the distal end of the tube adjacent the tissue site;

    inflating the balloon to dissect and form a void adjacent the tissue site for receiving a manifold comprising a cellular material having a plurality of flow channels adapted to distribute reduced pressure to the tissue site and a flexible, impermeable barrier to prevent transmission of reduced pressure away from the tissue site;

    rupturing or deflating the balloon after forming the void;

    delivering the manifold through the passageway into the void adjacent the tissue site;

    positioning the manifold such that at least one of the flow channels of the cellular material is in fluid communication with the tissue site; and

    applying a reduced pressure through a fluid-delivery tube in fluid communication with the flow channels of the cellular material for providing reduced pressure to the tissue site.
