Abstract
Dressings, systems, and methods for treating a tissue site with negative pressure are described. The dressing includes a manifold having a first surface and a second surface opposite the first surface, a first layer adjacent to the first surface, and a second layer adjacent to the second surface. The first layer and the second layer each are formed from a polymer film. A plurality of fluid restrictions are formed in the polymer film adjacent to at least the first surface. A first plurality of bonds is formed between the first layer and the second layer. The first plurality of bonds define separable sections of the manifold. A second plurality of bonds is formed between the first layer and the second layer. The second plurality of bonds define a plurality of openings.
