This chapter addresses the regulation of medical devices in the European Union. The overall goals of the European regulatory framework for medical devices are the same as the goals of the framework for medicines. It aims to protect public health by ensuring that medical devices are of good quality and safe for their intended use. However, the regulation of medical devices in Europe is very different from the regulation of medicines in two regards. First, unlike medicines, there is no pre-market authorisation by a regulatory authority for medical devices to lawfully enter the EU market. Second, unlike in the United States where the Food and Drug Administration is the primary regulator of devices throughout the nation, the European Union does not have a single regulator of medical devices. Instead, several organisations may be involved, and mainly a notified body in specific cases. The chapter then explains what constitutes a medical device in the EU and how devices are classified according to their level of risk in the EU. It then discusses how medical devices reach the market, how their risks are managed all along their lifecycle, and what kinds of incentives are provided for innovation and competition. The chapter also analyses the balance between public and private actors in the regulation of medical devices. It then concludes with case studies of innovative medical technologies that have challenged the traditional European regulatory scheme and that have led to many revisions in the 2017 device regulations.

The European regulatory framework is examined in relation to nanotechnology based medical devices and medicinal products. Medical applications of nanotechnology will have to comply with the requirement for a high level of public health, safety, consumer, and environmental protection. An evaluation of the possible health or environmental risks of nanoparticles must therefore be carried out and it is important to ensure that particle size and chemistry are taken into account when investigating possible adverse effects. Further research is needed on the toxicological and ecotoxicological properties of nanoparticles, their uptake in the body, accumulation in tissues and organs, transport characteristics, exposure and dose-response data, and their distribution and persistence in the environment. The existing regulations appear adequate to manage the risks of nanotechnology at its current stage of development but continuous review of the regulatory regime will be needed to determine whether it is sufficient to protect human health and the environment. Modification of the legislation may prove necessary as new scientific evidence emerges regarding the effects of nanoparticles on living organisms and in the ecosystems.

Ultraviolet radiation (UVR) from all three waveband regions of the UV spectrum, UVA (320-400 nm), UVB (290-320 nm), and UVC (200-290 nm), can be emitted by some medical devices and consumer products. Sunlamps can expose the blood to a considerable amount of UVR, particularly UVA and/or UVB. The percent transmission of each waveband through the epidermis to the dermis, which contains blood, increases in the order of increasing wavelength: UVC (10%) < UVB (20%) < UVA (30%). To investigate the effects of UVR on white blood cells, we chose transmission electron microscopy to examine the ultrastructure changes in L5178Y-R murine lymphoma cells.

Studies of bacterial behavior in many environments have shown that most organisms attach to surfaces, forming communities of microcolonies called biofilms. In contaminated medical devices, biofilms may serve both as reservoirs and as inocula for the initiation of infections. Recently, there has been much concern about the potential of dental units to transmit infections. Because the mechanisms of biofilm formation are ill-defined, we investigated the behavior and formation of a biofilm associated with tubing leading to the water syringe of a dental unit over a period of 1 month.

Very old studies and clinical experiences of physicians already signal the ability of some patients to feel subclinical signs. These patients are called sentinel patients because they can anticipate crisis very early and therefore intervene quickly to prevent them. Studies have shown that these patients develop these skills from their own experience, in steps which are similar to quasi-experimental research. They test and adjust their competence all the more easily as they have an objective external measure available. This faculty of patients suggests the possibility of using medical devices as a means of learning for patients to tutor themselves in support of this singular skill.
