The new European Medical Devices Regulation (MDR) and IVD Regulation (IVDR) has entered into force May 26th 2021 (EU no 2017/745, MDR). The MDR contains specific rules for the submission, assessment and conduct of clinical research on medical devices.
Software can also be a medical device. Software is a medical device if the manufacturer (or researchers) created the software for medical use. For example, an app for home monitoring of patients with heart failure. Regardless of where the software is used: with the patient at home or in the hospital.
