Abstract

In case of coronary arteriosclerosis and heart attack balloon-expandable stents are used. These balloon crimped implants are placed to the occluded vessel part and the balloons are pumped with big pressure (4-20 bar). The opened stents ensure the continuously flow of the blood in the opened lumen. The implants have to sustain the outer load from the vessel wall and have to keep the lumen open. In this study a method was worked out which valuating the radial force of the balloon expandable coronary stents. In an experimental program many types of methods were tested to find the best one.
