Biomechanical characteristics of the stent-coronary vessel system

The paper presents the biomechanical characteristics of the stent-coronary vessel system defined using the finite element method. Within the framework of the project the stress and strain distributions in the elements of the modelled system were determined for various stent form features, taking into account stent implementation stage and also its operation with the changing blood pressure. The results obtained may be a basis for optimization of the coronary stent shape and its form features, as well as of the properties of metallic material from which stents are made.
