A dual analysis of bougie and stylet development trend and impact of Chinese regulations on medical devices innovation.

Medical device research and development are characterized by high costs, extended timelines, inherent risks, and the necessity for interdisciplinary knowledge and skills. It is significantly influenced by policies, making the understanding of medical device innovation both important and challenging. This paper takes a dual approach to analyze medical device innovation. We reviewed representative clinical product of bougie and stylet and summarized the common characteristics and trend of these product. Innovations in these products often involve adding depth markings, replacing material and design structure, enhancing visualization, deciding between reusable or disposable designs, and integrating multi-functional features. This underscores the delicate balance between technological advancements and medical costs for widespread clinical applicability. We explored the guiding role of policy in medical device innovation, emphasizing its impact through an analysis of medical device regulations and policies in China. By offering insights from the perspectives of medical device companies and regulators, this paper aims to elucidate the critical aspects of medical device innovation, assisting researchers in mitigating risks during product development.
