The goal of this study is the analysis of physicomechanical properties of stent elements, theoretic-experimental researches of mechanical properties of wire stents. Stent is a small tube-like structure of biocompatible material which due to the elastic properties restores a lumens of vessels. Physical model of a vessel, as a rule, represent a multilayered shell with anisotropic properties. As mechanical properties of vessels can change in a wide range so the structure of stent will change accordingly. For definition of a rational stent structure, the basic mechanical properties are chosen, experimental and theoretical investigation of stent mechanical properties and its basic elements are made.
