Abstract

Provided are systems, dressings, and methods suitable for treating a tissue site, such as an incision or linear wound. The systems, dressings, and methods relate to a dressing assembly that may include a dressing bolster and a sealing ring. The sealing ring may be adapted to provide a fluid seal around the tissue site, and to absorb fluids from the tissue site. In some embodiments, the sealing ring may be extruded around the tissue site. In other embodiments, the sealing ring may be coupled to the dressing bolster. Other systems, apparatuses, and methods are disclosed.
