Abstract
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 A1. The foam spacer has a plan-view area A2. A2 is less than 80% of A1 (i.e., A2<0.8 A1). The foam spacer is configured such that, under reduced pressure, a target fluid removal zone experiences reduced-pressure vectors over an angle theta (θ) that is typically 360 degrees for a majority of locations in the 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.
