A kit and system for treating plaque formation in a patient's extremity are provided. A pressure pump and at least two elongated vacuum chambers are included in the kit and system. Each chamber has a proximal longitudinal end adapted to receive a patient's extremity and a distal longitudinal end adapted to be positioned in fluid communication with the pressure pump so that a pressure is created inside each of the at least two vacuum chambers and exerted upon the extremity received therein when the pressure pump is operating. One of the at least two vacuum chambers has a different inner circumference than another one of the at least two vacuum chambers so that a different level of prevention from bending is provided to the extremity in the direction of the plaque formation with each of the at least two vacuum chambers during operation of the pressure pump. Methods for treating plaque formation in a patient's extremity are also provided.
