IMDRF (International Medical Device Regulators Forum) was conceived in February 2011 as a forum to discuss future directions in medical device regulatory harmonization. It is a voluntary group of medical device regulators from around the world who have come together to build on the strong foundational work of the Global Harmonization Task Force on Medical Devices (GHTF), and to accelerate international medical device regulatory harmonization and convergence.
Due to Covid-19 outbreak, IMDRF recently published a list: IMDRF Standards Checklist modified in scope of COVID-19
