The Medical Device Regulation 2017/745 defines a ‘custom-made device’ as any device which is specifically made in accordance with a written prescription of any person authorised by national law by virtue of that person’s professional qualifications. This authorised person gives specific design characteristics provided under their responsibility. Moreover, such a custom-made device would be exclusive to one specific patient to meet their individual conditions and needs.
Adaptable medical devices or patient-matched medical devices are not categorized as custom-made devices. Adaptable medical devices are mass-produced medical devices which are adapted, adjusted, assembled, or shaped at the point of care to suit the individual’s features. Patient-matched medical devices are matched to an individual’s anatomy within a specified design envelope, is typically produced in a batch through a process, and is designed and manufactured under the manufacturer’s responsibility even though its design may be based on a healthcare professional’s authorization.
