Obtaining regulatory approval for medical AI products in the EU is a complex process that requires CE marking under the EU Medical Device Regulation (MDR), involving collaboration with a Notified Body and adherence to ISO 13485 quality management standards. Companies must define the Intended Use and classification of their devices, compile extensive documentation for Technical Files audits, and ensure compliance with data protection laws. Historically, medical devices have been regulated post-World War II, and with the rise of AI, software components are now considered medical devices requiring conformity assessment. The process involves significant documentation, including a Clinical Evaluation Report and a Declaration of Conformity, with audits focusing on employee adherence to documented procedures. While the regulatory landscape aims to protect patients, the rapid evolution of technology presents challenges for AI companies, especially startups, in navigating the regulatory framework. Collaboration and consulting with experts can mitigate these challenges, allowing successful market entry with CE-compliant diagnostic models.
