Abstract

This article introduces five measurement methods for investigation of functional properties of coronary stent systems. The properties were analysed in theory, and then several stents were measured and evaluated. Crossing profile, flexibility of the stent system, foreshortening, metallic surface area, the largest and the smallest cell sizes, the maximum achievable cell diameter and side branch access were measured. Four types of coronary stents were examined, two pieces from each type. The results show that the properties mostly depend on geometry, stent pattern and material. These investigations can help the physics to select the appropriate stent.
