Abstract

Claims (12)

1. A negative pressure wound therapy (NPWT) device for a deep abdominal wound, the NPWT device comprising:

a body comprising a porous material having a first compressive profile, the body including a plurality of removable portions supported by a substrate portion of the body, wherein each of the plurality of removable portions are individually surrounded by perforations or cuts in the substrate portion of the body such that the substrate portion of the body separates and surrounds the plurality of removable portions, none of the removable portions being surrounded by the perforations or cuts defining another of the removable portions, the substrate portion defining a free perimeter which surrounds all of the plurality of removable portions, each of the removable portions configured to define a void surrounded by the substrate portion of the body when removed, the plurality of removable portions configured to be selectively removed to form a pattern of voids within the substrate to transform the first compressive profile of the body into a second compressive profile based on the pattern of voids.

2. The NPWT device of claim 1 , wherein the first compressive profile is symmetric along a lateral axis and a longitudinal axis of the body, and wherein the second compressive profile is asymmetric across at least one of the lateral axis or the longitudinal axis.

3. The NPWT device of claim 1 , wherein the second compressive profile is different from the first compressive profile.

4. The NPWT device of claim 1 , wherein the plurality of removable portions include markings configured to indicate an increase in compressive force upon removal, at least one of the removable portions marked with a greater increase in compressive force than another of the removable portions.

5. The NPWT device of claim 1 , wherein the plurality of removable portions includes:

a first plurality of removable portions having a first shape, the first plurality of removable portions including a first marking configured to indicate a first amount of change in the second compressive profile upon removal of each one of the first plurality of removable portions; and

a second plurality of removable portions having a second shape different than the first shape, the second plurality of removable portions including a second marking configured to indicate a second amount of change in the second compressive profile upon removal of each one of the second plurality of removable portions;

wherein the second amount of change is greater than the first amount of change.

6. The NPWT device of claim 1 , wherein the body includes a first surface and a second surface, and wherein a fluid-impermeable layer is secured to the second surface and configured to face a fascia.

7. The NPWT device of claim 1 , wherein the body further comprises at least one plurality of sizing perforations that are spaced apart from the removable portions and follow a contour of the body.

8. The NPWT device of claim 1 , wherein the body is configured to compress in a first direction under negative pressure, and resist compression in a second direction perpendicular to the first direction under negative pressure.
