A clean narrative and a clear matrix mean fewer questions and a stronger submission. We evaluate your device’s materials, chemistry, and biological risks using ISO 10993-1 principles — then map these conclusions to the EU MDR General Safety and Performance Requirements.











ISO 10993-1 positions biological evaluation within a risk-management process. Under MDR, this approach is essential to demonstrate material safety, biological compatibility, and traceable justification for each biological effect.
Annex I §10 makes biological, chemical, and physical properties explicit obligations.
Your device must show:
Materials are safe for the intended body contact
Chemical and particulate risks are understood
Biological effects are assessed and justified
Testing is proposed only when needed based on risk
A structured evaluation avoids unnecessary testing, accelerates technical reviews, and ensures biological safety aligns with MDR expectations.
We start with ISO 10993-1 risk logic and then connect the outcomes to Annex I requirements — especially §10. The work is evidence-first, test-later.

Your MDR Biocompatibility Package includes:
Sobel supports global manufacturers with MDR submissions grounded in risk logic, evidence clarity, and regulatory traceability.
Our approach delivers:
ISO 10993-1 biological evaluation aligned with MDR expectations
Annex I mapping that demonstrates safety without over-testing
Traceable rationale from materials → evidence → conclusions
Fewer NB questions through clear documentation
Consistent application of risk-based evaluation across topics
Structured outputs aligned with Annex II and reviewer workflows
Our team develops a complete ISO 10993-1 biological evaluation supported by materials and chemistry evidence — then connects it to Annex I for a clean, defensible MDR submission.
