A wound treatment dressing for applying negative pressure wound therapy to a wound of an extremity, such as on the heel of a foot. The dressing comprises a fluid manifold 14 positioned within a fenestrated drape 16 to form a contoured occlusive wrapping 10 for placement over a wound on an extremity. A contoured porous pad 26 is placed adjacent or within the wound, such that the contoured pad 26 is enveloped by the occlusive wrapping 10. Flexible tubing 42 is attached to or through a fluid communication port 18, which forms an opening to the outer layer 16b of the occlusive wrapping 10, so as to allow for fluid communication of negative pressure to the contoured pad 26 from a source of negative pressure 44 connected to an opposite end of the flexible tubing 42. The negative gauge pressure is communicated from the source 44, through the tube 42, through the fenestrations 19 of the occlusive wrapping 10, such that negative gauge pressure is applied to the wound on the extremity. The fluid manifold 14 serves to direct the negative pressure from a position away from the wound site to the contoured pad 26 at the wound site.
