Abstract
A negative pressure wound therapy (NPWT) device for a deep abdominal wound. The compressive component includes a body having a first compressive profile. The body includes a plurality of removable portions of the material. The plurality of removable portions are configured to be selectively removed to form a pattern of voids to transform the first compressive profile of the body into a second compressive profile of the body based on the pattern of voids. The pattern of voids includes at least one void.

A negative pressure wound therapy (NPWT) device for a deep abdominal wound, the NPWT device comprising:
- a body having a first compressive profile, the body including a plurality of removable portions of the material, the plurality of removable portions configured to be selectively removed to form a pattern of voids to transform the first compressive profile of the body into a second compressive profile of the body based on the pattern of voids, the pattern of voids including at least one void.
19-20. (canceled)
A method for forming a negative pressure wound therapy (NPWT) dressing for a deep abdominal wound, the method comprising:
- selecting a first compressive material having a first compression ratio, the first compressive material including a first pattern of concentric perforations configured to form a plurality of first detachable compressive component segments;
- selecting a second compressive material having a second compression ratio different than the first compression ratio, the second compressive material including a second pattern of concentric perforations configured to form a plurality of second detachable segments;
- and
- forming the composite compressive component by:
- detaching at least one first compressive component segment from the first compressive material;
- detaching at least one second compressive component segment from the second compressive material, the at least one second compressive component segment including an opening configured for receiving the at least one first compressive component segment therein;
- and
- positioning the at least one first compressive component segment within the opening of the second compressive component segment to form the composite compressive component.
31-44. (canceled)
A negative pressure wound therapy (NPWT) dressing comprising:
- a central portion formed from a first compressive material having a first compression ratio;
- a first ring portion substantially surrounding the central portion, the first ring portion formed from a second compressive material having a second compression ratio;
- and
- wherein upon application of a negative pressure a lateral contraction of the ring portion is greater than a lateral contraction of the of the central portion.
