Abstract

The original method for restoring of the function of relatively incompetent valves and the design of the corrector for realization of the methods are elaborated. The principle of the corrector functioning is based on the shape memory effect, which permits to subject the design to significant plastic deformation at the temperature below zero. Being brought up to the place of implantation the corrector restores its initial ellipse-like form, surrounding the vein and changing its section in the necessary place. The method and the device were applied in the surgical treatment of 13 patients, aged from 20 to 72. The simplicity of the correction reduces the trauma possibility and allows to achieve adequate correction of the vein while reducing the obstacle of the venous blood flow makes this method favorable for wide application in clinical practice.
