A General Requirements

A1 Medical devices should be designed and

manufactured in such a way that, when used under

the conditions and for the purposes intended and,

where applicable, by virtue of the technical

knowledge, experience, education or training, and the

medical and physical conditions of intended users,

they will perform as intended by the manufacturer

and not compromise the clinical condition or the

safety of patients, or the safety and health of users or,

where applicable, other persons, provided that any

risks which may be associated with their use

benefits to the patient and are compatible with a high

level of protection of health and safety.

A2 The solutions adopted by the manufacturer for the

design and manufacture of the devices should

conform to safety principles, taking account of the

generally acknowledged state of the art. When risk

reduction is required, the manufacturer should

control the risks so that the residual risk associated

with each hazard is judged acceptable. The

manufacturer should apply the following principles

in the priority order listed:

• identify known or foreseeable hazards and estimate

the associated risks arising from the intended use

and foreseeable misuse;

3 Devices

C1 Chemical, physical and biological properties

C1.1 The IVD medical devices should be designed and manufactured in such a

way as to ensure the characteristics and performance referred to in Section 6.

Particular attention should be paid to the possibility of impairment of analytical

performance due to incompatibility between the materials used and the

specimens and/or analyte (measurand) to be detected (such as biological

tissues, cells, body fluids and micro-organisms), taking account of its intended

purpose.

C1.2 The IVD medical devices should be designed, manufactured and

packaged in such a way as to minimize the risk posed by contaminants and

residues to the persons involved in the transport, storage and use of the devices

and to patients, taking account of the intended purpose of the device.

C1.3 The IVD medical devices should be designed and manufactured in such a

way as to reduce as far as reasonably practicable and appropriate the risks

posed by substances that may leach or leak from the IVD medical device.

Special attention should be given to substances which are carcinogenic,

mutagenic or toxic to reproduction.

as to reduce as far as reasonably practicable and appropriate risks posed by the

unintentional ingress or egress of substances into or from the IVD medical

device taking into account the device and the nature of the environment in

which it is intended to be used.

C3 IVD medical devices incorporating materials of biological origin

C3.1 Where IVD medical devices include tissues, cells and substances

originating from animals, the processing, preservation, testing and handling of

tissues, cells and substances of animal origin should be carried out so as to

provide optimal safety for user, professional or lay, or other person.

In particular, safety with regard to viruses and other transmissible agents

should be addressed by implementation of validated methods of elimination or

inactivation in the course of the manufacturing process. This may not apply

to certain IVD medical devices if the activity of the virus and other

transmissible agent are integral to the intended purpose of the IVD medical

device or when such elimination or inactivation process would compromise the

NO

6 performance of the IVD medical device.

National regulations may require that the manufacturer and/or the Regulatory

Authority retain information on the geographical origin of the animals.

C3.2 Where IVD medical devices include human tissues, cells and substances,

the selection of sources, donors and/or substances of human origin, the

processing, preservation, testing and handling of tissues, cells and substances

of such origin should be carried out so as to provide optimal safety for user,

professional or lay, or other person.

In particular, safety with regard to viruses and other transmissible agents

should be addressed by implementation of validated methods of elimination or

inactivation in the course of the manufacturing process. This may not apply

to certain IVD medical devices if the activity of the virus and other

transmissible agent are integral to the intended purpose of the IVD medical

device or when such elimination or inactivation process would compromise the

performance of the IVD medical device.

C3.3 Where IVD medical devices include cells and substances of microbial

origin, the processing, preservation, testing and handling of cells and

substances should be carried out so as to provide optimal safety for user,

professional or lay, or other person.

In particular, safety with regard to viruses and other transmissible agents

should be addressed by implementation of validated methods of elimination or

inactivation in the course of the manufacturing process. This may not apply

to certain IVD medical devices if the activity of the virus and other

transmissible agent are integral to the intended purpose of the IVD medical

device or when such elimination or inactivation process would compromise the

performance of the IVD medical device.
