    Cobalt (Co) alloys are used extensively in a wide range of medical devices due to their biocompatibility, durability, and properties. In 2017 the European Chemical Agency (ECHA) proposed to classify Co metal as a category 1B carcinogen (i.e. presumed to have carcinogenic potential for humans), as a reproductive hazard category 1B (i.e. presumed human reproductive toxicant) and as a category 2 mutagen. Even more, the European Medical Device Regulation (MDR) requires that medical devices contain > 0,1 w/w of substances that are category 1 A and 1B (CMR). As far as the European Medical Device Regulation, it is not specified if the Co content and concentration had to be determined/measured on the entire product or only on the product components. The object of this work is the comparison of Co profile in three different suppliers of stainless-steel needles as is and after being processed (i.e. sterilized) and then provide the proper interpretation and application of MDR requirements. The study and the extractable profile demonstrate the low cobalt content on needles and on a total syringe, thus suggesting to consider the Co content only on the syringe component. © PDA, Inc. 2024.
