    摘要: A flow directing material includes a substrate. The substrate includes a first region that exudes fluid under a compressive or tensile load and a second region that imbibes fluid under the compressive or tensile load. The first region has a first porosity and a first permeability and the second region has a second porosity and a second permeability. The first permeability and the second permeability are about 10−13 m2 to 105 m2. The first porosity and the second porosity are about 0.3 to about 0.7. The first porosity and the second porosity are at least about 5% different.

    摘要: Described generally herein are tissue therapy devices, which may comprise a sealant layer and a suction apparatus. The sealant layer functions so as to create a sealed enclosure between it and the surface of a patient by forming, preferably, an airtight seal around an area of tissue that requires negative pressure therapy. The tissue therapy device may comprise a suction apparatus. The suction apparatus is typically in fluid communication with the sealant layer and functions so as to reduce the amount of pressure present underneath the sealant layer. The reduced pressure is self-created by the suction apparatus. Together the sealant layer and the suction apparatus preferably create a closed reduced pressure therapy system. Preferably, the pressure under the sealant layer is reduced by expanding the volume of the enclosure space and thereby decreasing the density of the air molecules under the sealant layer.
