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.
Claims12
A system for treating a deep abdominal wound, the system comprising:
- a wound dressing including:
- a visceral-protective layer configured to be positioned in an open abdomen;
- a compressive layer configured to be disposed proximate to the visceral-protective layer, wherein the compressive layer comprising a pattern of voids that includes a first ring of voids and a second ring of voids, and a pattern of perforations that includes a first ring of perforations positioned between the first ring of voids and the second ring of voids;
- and
- a sealing layer configured to form a sealed space in the open abdomen;
- and
- a negative pressure source configured to provide negative pressure to the compressive layer.
A system for treating a deep abdominal wound, the system comprising:
- a negative pressure source configured to provide a negative pressure;
- a wound dressing defining a longitudinal axis, the wound dressing including a compressive layer configured to resist compression in a direction normal to the wound dressing, the compressive layer including a pattern of voids, at least some of the voids having a concave surface and a convex surface, so that the convex surface follows a curved contour of the compressive layer and the concave surface faces toward the longitudinal axis, the pattern of voids configured to collapse in a greater amount in a substantially lateral direction than in a substantially vertical direction and a substantially longitudinal direction under the negative pressure, thereby exerting the a lateral compressive force towards the longitudinal axis.
