Abstract
An apparatus for tissue therapy may include a sequentially-collapsing tissue interface for use with negative pressure. The apparatus may include a first manifold and a second manifold fluidly coupled to the first manifold through a constricted fluid path. A fluid conductor may fluidly couple the second manifold to the first manifold. The fluid conductor may constrict fluid flow between the first manifold and the second manifold. The apparatus may include a negative-pressure source fluidly coupled to the first manifold in some embodiments. A controller may be configured to operate a negative-pressure source to provide negative pressure to a tissue interface in a therapy sequence adapted to propagate a wave in the tissue site. Such motion may be particularly advantageous or beneficial for a variety of conditions, including lymphedema, edema, or venous insufficiency.
