Shape memory stents are used for treating vascular conditions like myocardial infarction, angina, and arteriosclerosis through their shape memory behavior. These stents are inserted into blood vessels to expand them, and their performance in terms of flexibility, elastic recovery, and deformation is influenced by their design. In this study, parameters affecting stent structural design were analyzed using Taguchi method, aiming to design structures that consider flexibility, elastic recovery, and deformation. Reflecting the actual conditions faced by stents, ISO standards were incorporated, and finite element analysis was conducted, considering shape memory composite material properties obtained from tensile tests, specifically hyperealstic properties. Ultimately, statistical significance of stent structural design was evaluated through ANOVA (Analysis of Variance), and an improved optimal design model compared to the existing one was proposed.

The medical device industry is changing rapidly by applying the latest scientific and technological advancements. In particular, with the development of biotechnology, the proportion of in vitro diagnostic medical devices that diagnose diseases by analyzing body fluids such as blood and implant medical devices that can replace the role of human tissues and organs has recently increased rapidly In order to educate and supply manpower in the newly changing medical device industry, the development of a new practical training course is necessary. In this paper, we develop and report a hands-on training course using nitinol stents and a model stent introducer. The model stent introducer for this practical training can be easily made using raw materials used by the manufacturer, and the stents used in the training were provided by the stent manufacturing company. Through this practicum, students can experience part of the work of an actual medical device company and understand engineering theories applied to medical devices through practicum. In order for the Korean medical device industry to become a global leader, it is necessary to develop practical training courses through close cooperation between universities and industry.
