摘要：
A method and apparatus for disrupting material at a tissue site is described. A contact layer may be selected for use on the tissue site and positioned adjacent to the tissue site. The contact layer may include walls defining a plurality of through-holes. A sealing member may be positioned over the contact layer and sealed to tissue surrounding the tissue site to form a sealed space enclosing the contact layer. A negative-pressure source may be fluidly coupled to the sealed space. The negative-pressure source may supply negative pressure to the sealed space and the contact layer to draw tissue into the through-holes to form nodules. The negative pressure may be vented from the sealed space to release the nodules.
