FAQ Europäisches Biomedizinisches Institut
What is biocompatibility?
The concept of biocompatibility refers to the interaction between the tissues and the physiological systems of a patient treated with a medical device. The biocompatibility assessment is part of the overall device safety assessment.
Medical device biocompatibility assessment is actually carried out in order to ensure patient safety. When programming a biocompatibility test, manufacturers need to consider their compliance objectives and risks. In fact, medical device biocompatibility evaluation is a risk assessment study. All medical devices have a certain level of risk. Firms that design medical devices strive to maximize the benefits they provide to patients by minimizing risk.
The main standard in biocompatibility testing is the ISO 10993 standards. The first part of this standard is the test selection guide. The following sections cover specific test processes and other test related considerations.
Biocompatibility testing data is always required for devices with significant tissue contact. The ISO 10993-1 material biocompatibility matrix is used to determine whether a medical device requires a biocompatibility test. ISO 10993-1: 2018 through the Biological Evaluation Plan (BEP) allows to determine the potential risk based on the data provided by the Sponsor (information on raw materials, packaging, production conditions and previously performed studies). The next step is a series of studies proposed in the BEP to verify risk assessments, and finally in the Biological Evaluation Report (BER) risk assessment is summarized and explained what the potential sources of non-compliance could be.
The main purpose of the ISO standard is to verify that the device is suitable for the intended use. In this process, biological testing is the most important step in a biocompatibility assessment. The standard classifies devices by type of body contact and duration.
Biocompatibility is often associated with the necessity to perform a complete set of tests for new medical devices that are yet to be released on the market. But manufacturers of medical devices must remember that sometimes a seemingly small change in the production process of products already available on the market (for example: changing one of the materials, changing the production method, introducing new machines into the production line, or an apparently insignificant change in the sterilization method) is associated with another risk assessment and performing biocompatibility tests. Also manufacturers are required to collect safety data for all components and materials used in medical devices.

GLP
Quality system, that defines a set of rules and criteria for studies that are planned, performed and monitored, and their results are recorded, reported and archived. It is possible to trace the course of the study or its complete reconstruction.
ISO 17025
The quality management standard, implemented to standardize the technical requirements and requirements of the management system, intended for research laboratories in terms of testing and calibration. The objective of ISO 17025 is to promote the confidence in the operation of laboratories, to enable them to demonstrate they operate competently, and are able to generate valid results.
US FDA 21CFR58
Code of Federal Regulations of good laboratory practices for conducting nonclinical laboratory studies that support or are intended to support applications for research or marketing permits for products regulated by the FDA.
According to the ISO 10993-1:2018, B.4.5.3 any testing to support a biological evaluation has to be conducted in appropriate quality systems. The quality systems controls applicable to biocompatibility testing are known as Good Laboratory Practices (GLP). GLP studies are carried out to define quality standards in laboratories that are accredited in line with an internationally implemented governmental scheme. Those studies have to be conducted under a laboratory quality system compliant to ISO/IEC 17025 or an equivalent standard (GLP).
Furthermore, European Biomedical Institute is inspected and subject to constant supervision of the following Bodies:

Biocompatibility must be addressed - but what does it exactly mean?
According to the ISO 10993 standards and FDA requirements, biocompatibility must be addressed for each medical device. It is really important, since a significant amount of 510k submissions are rejected because of biocompatibility chapters are left empty…
We need to keep in mind that addressing biocompatibility does not mean each medical device has to be tested for biocompatibility! For instance, testing of a medical device that has no direct and in-direct contact may be impractical and even impossible. To highlight it, we may ask a question: how to test a medical device software for biocompatibility? The answer is simple: such testing is not necessary.
Therefore, for such cases the best way is to prepare a rationale/justification why biocompatibility testing was not performed – and it is a must! Such appropriate rationale or justification meet the requirements of addressing biocompatibility.

ISO 10993-1 Biocompatibility Matrix
An integral part of biological risk assessment, biocompatibility testing assesses the compatibility of medical devices with a biological system. It studies the interaction between the device and the various types of living tissues and cells that are exposed to the device when it comes into contact with patients.
Specific medical device safety evaluation programs follow ISO 10993 standards and the FDA guidance. EBI’s Biocompatibility Matrix is based on ISO 10993-1 Evaluation and Testing (2018), as well as the FDA Guidance (2020). While the matrix has been developed as a guideline for biocompatibility evaluation, it is essential that each device be evaluated based on its own unique characteristics.

Animal Facility
We have our own animal facility (vivarium)!
All activities related to the maintenance and use of laboratory animals are required by national and international standards and regulations. In our work, we operate in accordance with applicable legal regulations and the latest guidelines of non-governmental organizations.
- All procedures are carried out at European Biomedical Institute Animal Facility with the prior approval of the Local Ethics Committee.
- European Biomedical Institute Animal Facility is in the register of users of laboratory animals under the number 0054.
- Animal Facility is under the supervision of the Veterinary Inspectorate and National Ethical Committee for Animal Experiments.
- Personnel involved in the care of animals and carrying out procedures have the appropriate education, training and experience.
- At the European Biomedical Institute, the Animal Welfare Advisory Team is appointed for this purpose to ensure animal welfare.
Our unit is equipped with an innovative animal keeping system (IVC – individual ventilated cage). The living space for each individual complies with the requirements of national and international directives and standards. The ventilation system is equipped with devices that maintain constant temperature and humidity, and ensure a constant number of air changes. With the animals well-being in mind, each cage is equipped with elements to enrich the environment.
„3R” :Replacement, Reduction, Refinement
In our work, we use the principles of improvement and ethical use of laboratory animals described as “3R: Replacement, Reduction, Refirement”.
Whenever possible, we use the Replace method. The tests are then carried out by the European Biomedical Institute In Vitro Research Team. However, when it is not possible, we limit the number of animals used in experiments as much as possible and try to use methods that reduce animal suffering and improve animal welfare.
The vivarium consists of:
- Air-conditioned room to keep the rats
- Air-conditioned room to keep the mice
- Air-conditioned room to keep the guinea pigs
- Air-conditioned room to keep the rabbits
- Quarantine room
- Surgery room
