ABSTRACT:
A vascular assist device which maintains a static graduated pressure as the minimum pressure at all times during use. At least two inflatable chambers which wrap around selected portions of a limb apply elevated pressure to selected portions of a limb to disgorge blood therefrom. The inflatable chambers also apply static pressure which is graduated from distal to proximal along selected portions of a limb, such as from the ankle to the hip. A separate inflatable foot chamber can be included and is not necessarily utilized in conjunction with the compression phases for the ankle, calf, or thigh inflatable chambers. A desired pressure level is generated and maintained in a pressure accumulator, and a pressure regulator and regulator valve control the pressure in the inflatable chambers. The inflatable chambers between the ankle and hip are inflated to a predetermined and uniform dynamic pressure which is maintained in the inflatable chambers for a predetermined amount of time. The pressure is then decreased to a static pressure level which is graduated in pressure from the most distal inflatable chamber to the most proximal inflatable chamber between the ankle and the hip. The cycle is repeated after maintaining graduated static pressure for about forty five seconds.
