Biological Evaluation Supporting Safe Medical Devices

Scientific support for biological evaluation and biocompatibility according to ISO 10993.

Request a Consultation

Biological evaluation is a risk-based process used to assess the biological safety of medical devices throughout their lifecycle. Rather than relying solely on laboratory testing, ISO 10993 promotes a comprehensive evaluation that integrates material characterization, toxicological risk assessment, literature evidence and, where necessary, biological testing.

TOXENTRA provides independent scientific support for manufacturers throughout the biological evaluation process. Our approach combines current scientific evidence, regulatory expectations and internationally recognized standards to help demonstrate the biological safety of medical devices while avoiding unnecessary testing whenever scientifically justified.

Whether you are developing a new device, updating an existing product or preparing regulatory documentation, we provide tailored scientific solutions aligned with ISO 10993 and applicable regulatory requirements.

Questions

FAQ

What is a Biological Evaluation Report (BER)?+

A Biological Evaluation Report (BER) is a scientific document prepared in accordance with ISO 10993-1 that demonstrates whether the biological safety of a medical device has been adequately assessed. The report integrates available biological, chemical and toxicological information to determine whether the device is suitable for its intended clinical use.

When is ISO 10993 required?+

ISO 10993 should be considered whenever a medical device comes into direct or indirect contact with the human body. The extent of biological evaluation depends on the device's nature, duration of contact, materials, manufacturing process and intended clinical application.

Do all medical devices require biocompatibility testing?+

Not necessarily. ISO 10993 follows a risk-based approach. In many cases, existing biological data, chemical characterization, toxicological risk assessment and published literature may adequately demonstrate biological safety without conducting additional laboratory testing.

Can literature data replace biological testing?+

Yes, under appropriate circumstances. When sufficient scientific evidence and equivalent material information are available, a well-documented literature evaluation combined with toxicological assessment may reduce or eliminate the need for additional biological testing, provided this approach is scientifically justified and compliant with regulatory expectations.

What is the difference between a BEP and a BER?+

A Biological Evaluation Plan (BEP) defines the strategy for evaluating biological safety, while a Biological Evaluation Report (BER) documents the assessment process, supporting evidence and scientific conclusions regarding biological safety.

How can TOXENTRA support biological evaluation?+

TOXENTRA provides scientific support throughout the biological evaluation process, including Biological Evaluation Plans (BEP), Biological Evaluation Reports (BER), ISO 10993 gap analyses, toxicological risk assessments, literature evaluations and regulatory documentation tailored to project-specific requirements.
