A system and apparatus for promoting perfusion at a tissue site containing a sprain by applying a vacuum to intact skin extending over or surrounding the tissue site. The system and apparatus comprise a manifold formed from a porous material and configured to be disposed proximate the intact skin for distributing vacuum to the intact skin, and a sleeve adapted to cover the manifold and form a chamber containing the manifold to seal the manifold within the chamber between the sleeve and the intact skin. The system and apparatus further comprise a fluid coupling member adapted to deliver vacuum to the manifold for distribution to the intact skin. A method for applying vacuum to the intact skin of a tissue site is also disclosed and described herein.
