Understanding the requirements of selfexpandable stents

Several groups have pursued different ways to perform invitro assessments on selfexpanding nitinol stents. A comparison with prior art in the literature shows that a variety of tests have been performed to characterize stent forces and results are reported in dissimilar manners, making it difficult to use the outcomes to compare the performance of different stent designs (Table 1).

Effect of Stent Radial Force on Stress Pattern After

Introduction. The effectiveness of a stent lies in its capability to resist elastic outward recoil of the artery in which it has been implanted: a major indior of such feature is the stent radial force (RF) (Ref 1), which the manufacturers need to quantify according to international standards (Ref 2, 3) in order to obtain permission to market..
