The name Circulator Boot™ was chosen to indicate a device that benefited heart function and all of the circulations in the body: arterial, venous and lymphatic. It is noninvasive and its use is contraindicated only by the presence of fresh deep vein thrombi in the legs and/or aortic valvular insufficiency associated with heart failure. The Circulator Boot™ is more than a product. Its use in limb salvage has evolved into a Method of Treatment that supports the core elements of wound therapy: increased blood supply, bacterial control, moisture and debridement. Combined with the use of local antibiotic injections, for example, boot therapy may improve the blood supply and control the infection in patients with osteomyelitis and necrotizing cellulitis when standard methods of treatment are failing.
