The natural tapering of coronary arteries often creates a dilemma for optimal balloon sizing during stenting. The influence of different balloon types, namely, a tapered balloon and a conventional cylindrical balloon, on the mechanical performance of the stent as well as arterial mechanics was investigated via the finite element method. Stent free‐expansion and stent deployment in a stenotic tapered...
In-stent restenosis after stent deployment remains an obstruction in the long-term benefits of stenting. This study sought to investigate the influence of the relation between stent length and lesion length on the mechanics of the arterial wall with different geometries, including straight and tapered vessels. Results showed that when the length of the stent was longer than the lesion length, the...
Detachable transformer is an important component of contactless power transmission system. Compared with traditional transmission modes, it has following advantages. There is no contact between supplying equipments and loads, no friction, which brings convenience to maintenance; no noise pollution et al. It can work in any formidable conditions with higher frequency and less volume. This paper offers...
Cardiovascular stents are small cylindrical devices introduced in stenosed arteries to reopen the lumen and restore blood flow. High radial force has become an essential feature of new coronary stents. The primary aim of this investigation was to investigate the effects of varying stent "design parameter" on the radial force of stent by using the finite element method (FEM). The generic...
