Medical devices must be designed and manufactured, taking into account the generally recognised state of the art, in such a way that, when used in accordance with their intended purpose and under the conditions laid down for that purpose, they do not compromise, directly or indirectly:
1° the clinical condition and safety of patients ;
2° The health and safety of users or other persons;
3° the safety of property.
They are designed and manufactured, taking into account the generally recognised state of the art, in such a way that they can be used for their intended purpose, in accordance with the manufacturer’s instructions and achieve the performance levels set by the manufacturer and attested by a certificate of conformity in accordance with the legislative provisions of this chapter.
A secondary and undesirable effect is permissible only if it presents an acceptable risk in relation to the performance of the device.
