MEASUREMENT OF MECHANICAL PROPERTIES OF STENTS

摘要

The stents are the medical instruments used in invasive radiology for miniinvasive treatment of stenosis and aneurisms especially in the blood circulation system. Paper describes application of computer controlled device which was specially developed for measurement of mechanical properties of stents and vessels. This device together with the LabView programme enables automatic measurement of strain–stress curves of stents or vessels and in connection with the peristaltic pump can be used for the simulation of behaviour of stent inside the vessel system. All measurements are designed as a contactless and on-line so that the interaction of the measured sample with the probes and the mistakes due to insufficient synchronization of measurements are eliminated.
