Get reliable information on the formulation and purity of composition of chemicals used in your medical devices.What is Chemical characterisation of medical devices?
The chemical characterisation of materials is an essential aspect of the regulatory review and approval of medical devices in the European Union (EU) and most major markets worldwide. Chemical characterisation is also an essential aspect of the overall biocompatibility assessment process. This helps ensure that the potential biological risks from the device and its components do not outweigh the benefits of using the device.
Why chemical characterisation of medical devices is important
By design, most medical devices perform their functions through direct contact or implantation in the body. Some medical devices have indirect contact with the body through the gas pathway (like ventilators) or blood pathways (like dialysis machines).
This is why these medical devices should be tested to ascertain their chemical characteristics that could potentially impact the human body. Chemical characterisation may be used to identify and quantify chemical substances found in medical devices or materials that may contribute to the toxicological and biological risk management of the device.
Conducting a chemical characterisation consistent with the requirements of EN ISO 10993-18 is a critical aspect of a manufacturer’s overall effort to verify the safety of their medical devices. Information on the chemical composition of medical devices and materials intended to come into direct or indirect contact with a patient must be provided to obtain regulatory approval in North America, Europe and other important target markets like Greater China, Japan, Korea and Singapore, as part of the biocompatibility assessment process.
Given the complexity of the regulatory process, many device manufacturers are unaware of requirements for chemical characterisation of medical devices or don’t completely understand how the requirements apply to their devices. This can lead to interruptions in the approval process and delays in bringing their medical devices to market.
By understanding the importance of chemical characterisation and the specifics of the process, manufacturers can help ensure the chemical safety of their devices. A thorough evaluation increases the likelihood of a smooth and efficient regulatory review process.
