Abstract
A barrier for use in negative pressure wound therapy can include a base layer and surface structures. The barrier can be used to reduce or prevent tissue ingrowth. A method of using a negative pressure wound therapy system can include positioning a perforated barrier in a wound. After positioning the perforated barrier in the wound, positioning a pad in the wound on top of the perforated barrier, positioning a seal on top of the wound to at least partially seal the perforated barrier and the foam in the wound, and applying negative pressure wound therapy to the wound.
