Abstract
A dressing for treating tissue may be a composite of dressing layers, including a contact layer, a manifold layer, and an adhesive drape. The manifold layer may include one or more layers of felted open-cell foam in some examples. The manifold layer may be relatively thin to reduce the dressing profile and increase flexibility, which can enable it to conform to difficult geometry and other tissue sites under negative pressure. The dressing may have a length and a width less than the length. The manifold layer may include a population of holes extending at least partially therethrough, wherein the holes may be configured to promote anisotropic contraction of the dressing parallel to its width. The population of holes may have a circular, ovoid, triangular, square, hexagonal, irregular, or morphous shape. The dressing may be a bolster that may anisotropically contract to provide a closing force to a linear wound.
