A reduced-pressure abdominal treatment device is presented that has a plurality of liquid-impermeable layers with a foam spacer between two of the liquid-impermeable layers. The plurality of liquid-impermeable layers have a coextensive area A 1 . The foam spacer has a plan-view area A 2 . A 2 is less than 80% of A 1 (i.e., A 2 <0.8A 1 ). The foam spacer is configured such that, under reduced pressure, a target fluid removal zone experiences reduced-pressure vectors over an angle theta (˜) that typically 360 degrees for a majority of locations in target fluid removal zone. Applying 360 degrees of reduced pressure helps avoid blockage. The plurality of liquid-impermeable layers may be bonded for various effects. Other devices, systems, and methods are disclosed. |
