Medical devices: conformity assessment and the UKCA mark

AI Summary

This guidance from the UK Medicines and Healthcare products Regulatory Agency (MHRA) outlines the legal requirements for marking and selling medical devices in Great Britain and Northern Ireland. The regulatory framework is primarily based on the Medical Devices Regulations 2002 for England, Scotland, and Wales, while Northern Ireland adheres to EU medical device rules. To legally market a device, manufacturers must ensure it meets specific safety and performance standards through a conformity assessment. For Great Britain, products must feature the UKCA mark, whereas Northern Ireland requires the CE mark or a combined CE UKNI mark. Required actions for manufacturers include determining the device classification (Class I, IIa, IIb, or III) and choosing the appropriate assessment route. While low-risk Class I devices may often be self-certified, higher-risk devices require auditing and certification by a UK-approved body to verify quality management and risk assessment systems. Manufacturers are also expected to sign a formal declaration of conformity and may need to conduct clinical investigations to prove device safety. Exemptions apply to custom-made devices and those intended for clinical trials, though these must still meet basic safety obligations. Compliance with international standards, such as ISO 13485, is recommended to demonstrate adherence to these legal mandates.
