Abstract:
1. An abdominal treatment device for distributing reduced pressure to a tissue site, the abdominal treatment device comprising: a plurality of liquid-impermeable layers wherein the liquid-impermeable layers are at least partially fenestrated; a micro-channel space between the liquid-impermeable layers; a foam spacer disposed between the liquid-impermeable layers, wherein the foam spacer comprises arc members interconnected to form at least one window; and spacer bonds coupling at least two of the liquid-impermeable layers and disposed along a peripheral edge of the window; wherein the liquid-impermeable layers have a coextensive area A wherein the foam spacer has a plan-view area A wherein A wherein the foam spacer is configured such that, under reduced pressure, a location in the micro-channel space experiences reduced-pressure vectors over an angle theta (θ) that is at least 300 degrees.
