Abstract
A medical appliance worn about a patient's lower leg for treating venous insufficiency of the leg includes foot and leg portions having a hollow interior area extending therebetween for inflation into conformity with the patient's leg. When the patient is at rest, internal air pressure causes the stocking to function as an elastic stocking, but when the patient stands and walks, the force placed on the foot forces inflating air from the foot portion into the leg portion to increase the compressive action in the nature of a compression boot.
