Covidien's TED Hose are compression support stockings that are designed to prevent deep vein thrombosis. They help reduce venous pressure and relieve heavy, aching legs. These medical stockings increase the blood flow velocity in the legs by compressing the deep venous system. They are available in knee-high length or thigh-high length, as well as open or closed toe designs. Covidien's seamless, open toe design does not constrict the foot and is ideal for men and women. TED hose compression stockings are not recommended for patients who have a leg condition like dermatitis, immediate post-op vein litigation, gangrene, or those who have recently had a skin graft.
