1. A system for applying reduced pressure to a subcutaneous tissue site on a patient, the system comprising:

  • a reduced-pressure source operable to supply reduced pressure;

    a fluid source operable to supply a purging fluid;

    a manifold having a flattened shape including a flat side and an opposing side opposite the flat side, a width defined by the width of the flat side and a height defined by the distance between the flat side and the opposing side wherein the width is greater than the height, and a distal portion adapted to be inserted in the patient and placed at the subcutaneous tissue site, the manifold comprising;

    at least one purging lumen formed in the manifold and in fluid communication with the fluid source to deliver the purging fluid to the distal portion of the manifold,at least one slit formed in the flat side only at the distal portion of the manifold and adapted to be facing the subcutaneous tissue site, andat least one reduced-pressure lumen formed in the manifold, the at least one reduced-pressure lumen extending toward the distal end of the manifold and opening toward the flat side of the manifold to become the at least one slit, wherein the at least one reduced-pressure lumen is operable to deliver reduced pressure supplied from the reduced-pressure source to the subcutaneous tissue site via the at least one slit; and

    a delivery tube in fluid communication with the manifold, the delivery tube having at least one reduced-pressure delivery lumen adapted to deliver reduced pressure to the at least one reduced-pressure lumen and having at least one fluid delivery lumen adapted to deliver the purging fluid to the at least one purging lumen.
