A Comparative Study of Medical Device Regulations:: US, Europe, Canada, and Taiwan.

The medical device industry is an industry dealing with multiple types of products covering a wide range of applications. As the safety and effectiveness of medical devices are vital to human health, the products must be managed by strict regulations according to the different risk levels. A total product life cycle regulatory system including product design, manufacture, premarket gate keeping, and postmarket monitoring is a common framework for medical device regulations. However, the variety and innovativeness of medical devices are challenging the current regulatory frameworks. Hence, the competent authorities responsible for medical devices worldwide keep renewing their regulatory systems to ensure the safety and effectiveness of medical devices. This review aims to provide an informative review of the regulatory frameworks of medical devices in the United States, Europe, Canada, and Taiwan, with a particular focus on updated regulatory changes in these countries and the current status of global harmonization on medical devices.
