FILAB is the first French laboratory to be ISO 17025 accredited by COFRAC for ISO 10993-18 testing. Relying on this experience, we have mastered the characterization of a large number of medical devices. Therefore we are able to assist with the whole of the ISO 10993 standard set of procedures.

ISO 10993-1 (BRA)

Assessment and testing within a risk management process

ISO 10993-18

Chemical characterization of medical device materials within a risk management process

ISO 10993-17 (TRA)

Establishment of allowable limits for leachable substances

• Why do you need to subject your medical device to an ISO 10993-18 chemical characterization before putting it on the market?

In order to test the biocompatibility of your medical device, qualitative and quantitative data must be collected on the materials that make up the devices in the context of biological safety. In the absence of such information, the material should be tested using appropriate techniques to collect data on its composition and its potential extractibles.

• What results can you expect from this analytical chemical characterization?

The objective of this analytical expertise will be to identify and quantify the soluble and insoluble elements that will potentially be released from the Medical Device.

• My Medical Device is unique, how can FILAB characterize it according to the ISO 10993-18 standard?

ISO 10993-18 standard lays the foundation for the characterization, identification and quantification of all medical devices. Considering the great diversity of medical devices, it is necessary to adapt the chemical characterization to the specificity of each one. In this sense, it is important to be supported by a laboratory with the necessary skills and equipment.

• When should ISO 10993-18 testing be performed?

The ISO 10993-18 standard tests must be performed when developing a new medical device, when changing the manufacturing process or when changing materials and/or suppliers. Please be aware that even if a material has been historically shown to be biocompatible, it must still pass the ISO 10993-18 tests.

• Simulated, exaggerated or exhaustive extraction?

  • Simulated extraction: An extraction with simulated use is performed to estimate the type and quantity of substances expected to be released from a medical device during its clinical use
  • Exaggerated Extraction: Extraction intended to result in the release of a larger number or quantity of chemical constituents than would be produced under clinical conditions of use
  • Exhaustive Extraction: Multi-stage extraction performed so that the amount of extracted material recovered in a later step is less than 10% of that detected, by gravimetric analysis (or by any other means), in the initial extraction step

Presentation of our offer

• Calculation of the AET

Already used in the pharmaceutical industry, the AET (Analytical Evaluation Threshold) allows the correlation of a toxicological threshold (in µg/medical device or in µg/day) to an analytical threshold (µg/mL).

The AET (Analytical Evaluation Threshold) is, according to ISO10993-18, an « analytical evaluation threshold below which the analyst is not required to identify or quantify releasable or extractable products or to report them for possible toxicological evaluation. »

• Exhaustive extraction according to ISO 10993-12

For the ISO 10993-18 chemical characterization, your medical device is immersed into neutral solvents (water, acetonitrile, ethanol, isopropanol…) according to the methods adapted to its use. At the end of this immersion, the analysis of extracts allows us to identify the chemical species that can be released from the part of the medical device, and to estimate the quantities by means of simulation solvents after application of a thermal stress
