First claim
Opening claim text (preview).
The invention claimed is: 1. A wound insert for use with a wound dressing, the wound insert comprising: a foam having high-density regions and low-density regions, the high-density regions having a density of between 1.2 to 4 times the density of the low-density regions; and a drape for coupling to skin of a patient adjacent a wound to which the wound dressing is applied such that the drape covers the wound insert and the wound, and forms a space between the drape and the wound. 2. The wound insert of claim 1 , wherein the foam comprises a hydrophilic foam. 3. The wound insert of claim 1 , wherein the high-density regions and low-density regions are configured in alternating rows. 4. The wound insert of claim 1 , wherein the high-density regions and low-density regions are configured in a grid pattern. 5. The wound insert of claim 1 , wherein the low-density regions have a density that is less than a density of the high-density regions when the foam is positioned in a compressed configuration. 6. The wound insert of claim 1 , wherein the high-density regions are configured to contract less under negative pressure than the low-density regions under the negative pressure.
