Experimental Study on Fatigue for Stent with Micropores

Abstract:

To eliminate the risk of late and very late stent thrombosis of permanent polymer stent, a polymer-free stent direct drug-loading by micropores is developed. To evaluate the safety of micropores stent, fatigue test for micropores stent is carried out. The result is that micropores stent still maintain integrity and has no difference found in comparison with the initial state after 400 mio fatigue cycles --corresponding to about 10 years. The result proves that the fatigue durability of micropores stent is safe, which may help to promote the use of polymer-free stent direct drug-loading by micropores.
