Risk management is the process that helps to identify hazards, analyze them, and then to create an action plan to avoid and mitigate these hazards. The main objective of risk management in product development and manufacturing is to provide safe and efficient products without spending too many resources. Medical device manufacturers also face enormous risks - regulatory, legal, and financial - based on their products and processes, and the concepts of risk management are particularly important because any single failure may result in serious damages to body or loss of life. In this regard, a set of guidelines for the application of risk management to medical devices has been issued by ISO and specified in the document ISO 14971 Medical devices - Application of risk management to medical devices. The main objective of this study is to investigate the application of risk management to dental implant development and manufacturing processes based on ISO 14971. A general risk management process is first introduced, and the application of ISO 14971 to dental implants is further investigated.

EN ISO 14971:2012 a risk management standard approved and applied as a European standard in 2012, will be adopted and applied as ISO 14971:2019 published in December 2019, ISO/TR 24971(Guidance) published in June 2020 from May 2022. After that, it is applied to IVDD surveillance and IVDR new and conversion, and the manufacturer is already preparing for application or is starting preparation for application. In addition, 98/78/EEC IVDD applied from 1998 will also be applied as REGULATION (EU) 2017/746 IVDR from May 2022. In particular, in IVDR, the requirements for post-marketing investigations such as Post Market Surveillance (PMS), Summary of safety and performance(SSP), Periodic Safety Update Report(PSUR) and Post Market Performance Follow Up(PMPF), which were not required in the existing IVDD, increased, and the contents were also specified. This study focused on ISO14971:2019 among these strengthened and newly applied regulations, and tried to present a detailed analysis and application plan of Post Market Surveillance (PMS) required by 2017/746 IVDR.

Purpose: It can easily be understood that more rules and regulations need to be imposed on the medical device industry due to its impact on public health and hygiene. Domestic medical device manufacturers are thus required to comply with the requirements specified in the good manufacturing practice (GMP) system, and it is essential to abide by the international standards as well to sustain their global competitiveness. The main purpose of this study is to review the guidelines of the medical device GMP system in Korea and propose future directions for further enhancement of the GMP system. Methods: Specific requirements prescribed in international standards, such as ISO 9001:2015, ISO 13485:2016, ISO 14971:2012, and ISO 14155:2011, are analyzed and compared with the domestic GMP system. Results: It has been observed that the generic international standard related to quality management system, ISO 9001:2015, lays out the foundations for the development of quality management system relevant to medical device industry, ISO 13485:2003, with which the domestic GMP system is fully compatible. Further, several important aspects of risk management and clinical trials of medical devices are also recognized and included in the domestic medical device GMP system. Conclusion: Even though specific requirements of individual ISO standards are slightly different from each other, their overall structure and framework may contribute to the development and enhancement of globally competitive GMP system of the domestic medical device industry.

The purpose of this study is to provide basic data to ensure the safety and essential performance of a Lower Extremity robotic assisted gait training system and to provide advanced technology and technical basis to the industry handling the system. Based on IEC 60601-1:2012/AMD2:2020 (Medical Electrical Equipment - General requirements for basic safety and essential performance of medical electrical equipment), IEC 62366-1:2015/AMD1:2020 (Medical devices - Part 1: Application of usability engineering to medical devices) and EN ISO 14971:2019 (Medical devices - Application of risk management to medical devices), the requirements for ensuring the safety and essential performance of the Lower Extremity robotic assisted gait training system were derived. Through the Delphi survey method and scenario analysis, which reflects the opinions and knowledge of experts in the fields of development, testing and review of technical documents, and quality assurance of medical devices, validity and reliability were conducted and obtained results with adequate content validity ratio (CVR; 0.7≤) and excellent reliability (Cronbach's α; 0.9≤). As a result, it was confirmed that the reliability and validity of the risk management process to ensure the safety and essential performance of the Lower Extremity robotic assisted gait training system are required a model can be established to provide measures to reduce risks according to the level of risk exposure caused by usage.
