Abstract:
1. A reduced pressure treatment system for delivering a reduced pressure to a tissue site comprising: a distribution manifold including a backing substrate having a first side adapted to face a tissue site, a second side opposite the first side, and a plurality of protrusions extending from the first side of the backing substrate, wherein the plurality of protrusions have a substantially circular cross-sectional shape having a width between about 0.1 and 2.0 millimeters and a height greater than the width, and wherein the backing substrate has a plurality of apertures formed between the first side and the second side to allow fluid communication between the first side and the second side; and a reduced pressure source adapted to be fluidly connected to the apertures on the second side and configured to deliver reduced pressure through the apertures to the first side between the protrusions and to the tissue site; whereby the protrusions maintain a specific height to width ratio that prevents new tissue growth from attaching to the distribution manifold.
