1. An apparatus for treating a tissue site, comprising:
a contact layer formed from a compressible material, the contact layer comprising a plurality of apertures defined by walls extending at least partially through the contact layer;
at least a portion of the apertures including a plurality of orifices disposed on a surface of the contact layer; and
a cover configured to form a sealed space including the contact layer and the tissue site;
wherein the contact layer has a first thickness at an ambient pressure, the contact layer is configured to compress to a second thickness in response to a reduced pressure applied to the sealed space, the plurality of orifices are configured to receive tissue to form nodules at the tissue site in response to the reduced pressure, and the nodules have a height no greater than the second thickness.
