Abstract
A system for treating a deep abdominal wound. The system includes a wound dressing. The wound dressing includes a visceral-protective layer, a compressive layer, and a sealing layer. The visceral-protective layer is configured to be positioned in an open abdomen. The compressive layer is configured to be disposed proximate to the visceral-protective layer. The compressive layer includes a pattern of voids configured for anisotropic collapse of the compressive layer when under negative pressure. The sealing layer is configured to form a sealed space in the open abdomen. A negative pressure source configured to provide negative pressure to the compressive layer.
