When planning to make a custom-made device for a customer, what CE marking strategy is required?

The correct response highlights the understanding of regulations regarding custom-made medical devices within the European market. Specifically, for custom-made devices, the CE marking is not required; instead, the Declaration of Conformity (DoC) is mandatory. The DoC demonstrates that the manufacturer attests to the compliance of the custom-made device with relevant regulations or standards, although this compliance doesn't necessitate the formal CE marking typically required for mass-produced devices.

Member States may also request a list of custom devices to ensure that all specific products in their jurisdiction meet safety and regulatory standards. This strategy allows for proper oversight while still accommodating the unique nature of custom devices that are intended for individual patients and prescribed by medical professionals.

The other options suggest that a CE mark is required, which contradicts the specific regulations for custom-made devices, or they misinterpret the requirements surrounding the DoC and CE marking related to custom medical devices. This clarifies the regulatory landscape for manufacturers wishing to create devices tailored to individual patient needs within the EU.
