Reduced-pressure dressings employing tissue-fixation elements
A reduced-pressure system for treating a tissue site on a patient includes a distribution manifold that adheres to a tissue site to allow retention without external support. The distribution manifold includes a porous member and a tissue-fixation element. The tissue-fixation element maintains the porous member substantially adjacent to the tissue site while a sealing member is applied. In one instance, the tissue-fixation element is a soluble adhesive that partially covers either the tissue-facing side of the porous member or a tissue-facing side of a fluid-permeable substrate layer that is on the tissue-facing side of the porous member. Other systems, distributions manifolds, and methods are presented.

Systems and methods for distending a tubular organ and / or enhancing nutrient absorption
Plicator systems may have two telescoping components that when arranged in an open configuration have one or more windows into which tissue of, for example, a tubular organ may be invaginated. The invaginated tissue may be secured in the window when the plicator system transitions to a closed configuration. Closing the window may act to, for example, clamp, pierce of the tubular organ tissue invaginated into the window, thereby securing the invaginated tubular organ tissue into the window. In some instances, an axially-expanding spring may be disposed between two plicator systems and when this assembly is implanted in a tubular organ, axial expansion of the spring may exert a distending force on the tubular organ, which may stimulate growth of the tubular organ.
