TL;DR: A finite element method (FEM) model was built which is composed of a stenotic carotid tissue, a segmented-design nitinol stent and a sheath, and results show that the superelastic stents were delivered into the stenotic vessel lumen through the sheath and self-expanded in the internal and commonCarotid artery.

TL;DR: The results of shape-setting, austenite finish temperature and nonlinear mechanical properties of Ni stent wires at body temperature were investigated in this paper, which showed that the shape setting results were stable when wires were constrain-treated at 500 and 550°C and the ageing time was longer than 10min.

TL;DR: In this paper, the open circuit potential of the laser-welded NiTi alloy and base metal in 0.9% NaCl solution were investigated by means of electrochemical techniques.

TL;DR: In this paper, the authors used open circuit testing and electrochemical impedance spectroscopy (EIS) to study the corrosion performance of the TiN coated samples in Troyde's simulated body fluid.

TL;DR: In this article, the influence of heat treatment on the rotating bending fatigue of a laser-welded superelastic NiTi alloy wire was investigated, and it was shown that annealing at 400°C for 1h shows the best fatigue resistance.
