Application problems of implants used in interventional cardiology

The paper discusses application issues of using the metal implants for treatment of the cardiovascular diseases. The analysis of the biophysical conditions of the heart-coronary vessels system has been used to distinguish the tissue environment properties which should be compatible with properties of the metal biomaterial and stent surface. The need to determine the correct quality and service properties of the coronary stents has been indicated, which refer first of all to their design form, physical and chemical properties of the metal biomaterial and its surface. Based on that the Author of the work has proposed his own methodology for forming and controlling the service properties of the stents. It takes into account the required relationships between structure, and mechanical properties of the stent biomaterial, and the physical and chemical properties of its surface - adjusted to the specific features of the cardiovascular system.
