« medical device » means any instrument, apparatus, appliance, software, material or other article, whether used alone or in combination, including the software intended by its manufacturer to be used specifically for diagnostic and/or therapeutic purposes and necessary for its proper application, intended by the manufacturer to be used for human beings for the purpose of: Diagnosis, prevention, monitoring, treatment or alleviation of disease, Diagnosis, monitoring, treatment, alleviation of or compensation for an injury or handicap, Investigation, replacement or modification of the anatomy or of a physiological process Control of conception And which does not achieve its principal intended action in or on the human body by pharmacological, immunological or metabolic means, but which may be assisted in its function by such means Definitions 8
«active medical device » means any medical device relying for its functioning on a source of electrical energy or any source of power other than that directly generated by the human body or gravity « active implantable medical device » means any active medical device which is intended to be totally or partially introduced, surgically or medically, into the human body or by medical intervention into a natural orifice, and which is intended to remain after the procedure « accessory » means an article which whilst not being a device is intended specifically by its manufacturer to be used together with a device to enable it to be used in accordance with the use of the device intended by the manufacturer of the device Definitions 9
