Design controls are the application of a formalmethodology to the conduct ofproduct development activities.It is often mandatory (by regulation) to implement such practice when designing and developing products within regulated industries (e.g.medical devices).
Since 1990, theFood and Drug Administration (FDA) has required thatmedical device manufacturers that want to market certain categories of medical devices in the USA follow Design Control requirements (21 CFR 820.30). At a high level, this regulation requires:
TheMedical Devices Regulation (MDR (EU) 2017/745), replacing the MDD from 2021, requires information to allow the design stages applied to the device to be understood as part of the design and manufacturing information of a technical documentation for a medical device.
ISO 13485 is a voluntary standard that contains section 7.3 Design and Development recommending which procedures should be put in place by manufacturers in order to have a quality system that will comply with either the IVDR or the MDR.
The objective of Design Controls, in this context, is to require that manufacturers follow a methodologically-sound process to develop a medical device, with the intent of improving the probability that the device will reach an acceptable level ofefficacy and safety.
