Abstract: A dressing configured to provide radial or semi-radial expansion to a tissue site, which can increase the flow of fluids in and around the tissue site. The dressing may include an adhesive and a spring or biasing member that is able to expand radially while the dressing is worn, resulting in opening the tissue site to greater lymphatic flows. For example, the biasing member may partially or completely encircle the tissue site, allowing for radial force to be directed over the majority of the tissue site. The biasing member may have an unloaded state and a loaded state, and may be biased to the unloaded state. The dressing may also include a conformable layer between the biasing member and the adhesive. The conformable layer may conform to the contours of the anatomy of the patient. The conformable layer may increase the comfort of the dressing.
