Safety, Efficacy Tests and Classification of Medical Devices
Make sure that your medical devices comply with national, international and European standards and regulations
Do you want to make sure your Medical Device is safe and efficient?
Abich - Lifeanalytics laboratory can test any product and device with diagnostic or therapeutic purposes.
From design to marketing, one of the crucial stages in the creation of an innovative medical device is making sure that it complies with standards and regulations.
Regulation (EU) 2017/745 and Regulation (EU) 2017/746 are the reference points specifying that the difference with a medication is the mode of action, which is physical for medical devices: electrical conduction, mechanical stimulation, thermal activity, etc. The regulations provide that these devices must comply with specific and detailed essential requirements. Therefore, they need to undergo numerous safety and efficacy tests in compliance with the strict protocols of the international (ISO), European (EN) and national (UN) technical reference standards and also classification tests in line with the new European regulation on medical devices.
Definition of Medical Device according to Regulation (EU) 2017/745 and Regulation (EU) 2017/746
Medical device means “any instrument, apparatus, appliance, software, implant, reagent, material or other article intended by the manufacturer to be used, alone or in combination, for human beings for one or more of the following specific medical purposes:
- Diagnosis, prevention, monitoring, prediction, prognosis, treatment or alleviation of disease,
- Diagnosis, monitoring, treatment, alleviation of, or compensation for, an injury or disability,
- Investigation, replacement or modification of the anatomy or of a physiological or pathological process or state,
- Providing information by means of in vitro examination of specimens derived from the human body, including organ, blood and tissue donations,
and which does not achieve its principal intended action by pharmacological, immunological or metabolic means, in or on the human body, but which may be assisted in its function by such means.”
The Italian regulations on Medical Devices
The Italian laws transposing the European Community Directives divide medical devices into three different categories:
- Active Implantable Medical Devices (Directive 90/385/EEC; Italian legislative decree 14 December 1992, No. 507),
- Medical Devices (in general), (Directive 93/42/EEC; Italian legislative decree 24 February 1997, No. 46),
- In vitro Diagnostic Medical Devices, (Directive 98/79/EEC; Italian legislative decree 8 September 2000, No. 332).
The classification of Medical Devices
In addition, medical devices are divided into 4 classes, from the least critical to the most critical, as described in Annex IX of Italian Legislative Decree 24 February 1997, No. 46: I, IIa, IIb, III.
The classification depends on the complexity of the medical device and the potential risk for the patient on the basis of three factors:
- Invasiveness: depending on the degree of penetration of the medical device into the human body,
- Duration of use: if the medical device needs to be used only once or for a longer period of time,
- Dependence on sources of energy.
On the basis of this classification, medical devices have to follow very different procedures to obtain conformity (CE marking):
- Class I: the compliance evaluation procedures can be ‘self-certified’ by the manufacturer under its sole responsibility,
- Class IIa: the notified body intervenes only for controls during manufacturing; the package leaflet is not required,
- Class IIb: the notified body intervenes both during design and manufacturing. The package leaflet is required,
- Class III: the notified body intervenes both during design and manufacturing. A prior authorisation with regard to the conformity of the device is required. The package leaflet is required.
Medical Devices according to Regulation EU 2017/745 (MDR)
The Regulation introduced the concept of ‘devices composed of substances‘. Their classification is defined on the basis of the new Rule 21 (Annex VIII).
What does Rule 21 envisage?
The devices composed of substances or of combination of substances that are intended to be introduced into the human body via a body orifice or applied to the skin and that are absorbed by or locally dispersed in the human body are classified as:
- Class III if they, or their products of metabolism, are systemically absorbed by the human body in order to achieve the intended purpose,
- Class III if they achieve their intended purpose in the stomach or lower gastrointestinal tract and they, or their products of metabolism, are systemically absorbed by the human body,
- Class IIa if they are applied to the skin or if they are applied in the nasal or oral cavity as far as the pharynx, and achieve their intended purpose on those cavities,
- Class IIb in all other cases.
