Abstract
A reduced pressure treatment system is provided for delivering a reduced pressure to a tissue site comprising a distribution manifold including a backing substrate with a first side and a second side and a plurality of protrusions positioned on the first side of the backing substrate, each of the protrusions having a substantially circular cross-sectional shape and having a diameter of between about 0.1 and 2.0 millimeters, the backing substrate having a plurality of apertures formed therein to allow fluid communication between the first side and the second side opposite the first side. A reduced pressure source fluidly connects to the apertures of the backing substrate to deliver the reduced pressure through the apertures, between the protrusions, and to the tissue.
