On 29 June 2026, the European Commission published two delegated regulations in the Official Journal of the EU that broaden the category of “well-established technologies” (WET) under the Medical Devices Regulation (MDR).
WET devices are relatively simple products with common, stable designs, well-characterised safety and clinical performance, and a long market history. Expanding the list allows certain MDR requirements to apply more proportionately to these devices, reducing manufacturer burden in line with the Commission’s simplification agenda. The list was developed during 2025 by a dedicated Task Force of national experts under the Medical Device Coordination Group (MDCG), following a call for evidence with stakeholder input.
The two acts are:
- Delegated Regulation (EU) 2026/1451 — updating the list of implantable and class III devices exempted from the obligation to perform clinical investigations.
- Delegated Regulation (EU) 2026/1359 — updating the list of class IIb implantable devices exempted from per-device technical documentation assessment.
Both will make life easier for manufacturers as they reduce the range of devices for which a clinical investigation is required by default. At the same time notified body review activities are reduced for a larger range of devices with the updated provisions.
The acts entered into force 20 days after publication. Manufacturers of affected devices should review whether their products now qualify for these exemptions and adjust conformity assessment planning accordingly.
