Biocompatibility Documentation
That Holds Up Under
EU MDR and FDA Review
I help MedTech startups, manufacturers, and RA/QA teams build BEPs, BERs, TRAs, and remediation packages around the actual device, the available evidence, and the pathway under review.
Typical High-Priority Projects
Where teams usually need help fast
Aligned with the frameworks reviewers actually scrutinize
Built for teams that need a clear submission path, not generic template writing
I typically support teams that already have a device, a regulatory target, and a concrete documentation problem to solve.
MedTech Startups
Founders and first-time submission teams that need a defensible BEP, BER, or biocompatibility plan from scratch.
RA/QA Teams
Regulatory and quality teams that need expert support on endpoint strategy, waiver justification, or document review before submission.
Manufacturers Updating Legacy Files
Companies upgrading older BEPs and BERs to align with ISO 10993-1:2025, lifecycle framing, and current reviewer expectations.
Submission Consultants
Consultants and cross-functional teams that need specialist ISO 10993 input for FDA, EU MDR, or deficiency-response packages.
Best when these details are already clear
The clearer the starting inputs are, the faster I can assess scope, identify likely documentation gaps, and recommend the next practical step.
When those basics are defined upfront, scope review is usually faster and the work can start with fewer back-and-forth questions.
Devices I Work With
If your device touches, implants into, or communicates with the human body — I can prepare the biological evaluation documentation.
Implantable Devices
Long-term and permanent implants — the most demanding biocompatibility category requiring full endpoint coverage and genotoxicity assessment.
Wound Care & Dressings
Surface-contacting devices with intact or compromised skin contact. Biocompatibility assessment for wound care materials and dressings.
Catheters & Tubing
Short and long-term blood/tissue contact devices. Chemical characterization, extractables assessment, and TRA for polymeric materials.
Dental Devices
Oral contact devices including restorative materials, surgical instruments, and orthodontic devices requiring ISO 10993 biological evaluation.
Cardiovascular Devices
Blood-contacting devices with critical biocompatibility requirements including thrombogenicity and haemocompatibility endpoint evaluation.
Diagnostic & IVD-Adjacent
Devices that contact the patient during diagnostic procedures — biosensors, imaging probes, and electrochemical sensors.
Orthopaedic Devices
Bone-contacting implants and fixation devices requiring genotoxicity, implantation, and systemic toxicity endpoint evaluation.
Ophthalmic Devices
Devices in contact with ocular tissue — a sensitive contact category requiring careful material selection and cytotoxicity evaluation.
Not sure if your device fits? Send me a brief description — I'll confirm scope and timeline within 24 hours, no obligation.
Common ISO 10993 Problems I Solve
Medical device companies face recurring biological evaluation challenges. I specialize in resolving each one.
Notified Body Query on BEP/BER
Your notified body flagged gaps in your biological evaluation plan or report. I prepare structured, scientifically justified responses.
Notified Body ResponseUncertain Which Tests to Waive
ISO 10993-1 allows test waivers with proper justification. I identify which endpoints can be justified and prepare the scientific rationale.
Test Waiver JustificationFirst Biocompatibility Assessment
MedTech startups preparing their first biological evaluation documentation. I build scientifically defensible BEPs from scratch.
Full BEP DevelopmentFDA 510(k) Section Rejected
Your biocompatibility section was rejected or flagged by FDA. I prepare FDA-aligned documentation per the FDA biocompatibility guidance (2020, updated 2023).
FDA Section RemediationMaterial or Design Change
Device material or design change triggers a biocompatibility re-evaluation. I perform change impact assessments aligned with ISO 10993-1.
Change Impact AssessmentLegacy BER Needs Update

Best first step when a draft file already exists and the team needs to know whether it is usable, weak in key places, or headed toward reviewer friction.
See how the review is packaged Pre-submissionSelected India / CDSCO support and adjacent work such as CER, PMCF/PMS, and scientific writing remain available, but the homepage stays focused on ISO 10993 documentation and submission-facing remediation. If your team already has a draft file, the review offer is usually the cleanest first step.
Real Biocompatibility Science, Not Template Writing
I have personally conducted cytotoxicity assays, studied inflammatory responses to biomaterials, and published research on biological evaluation endpoints. With 10+ years in biomaterials science and hands-on bench experience, when I write your BER, I understand the science behind each endpoint — not just the regulatory requirement.
Bench-Level Research Experience
Hands-on cytotoxicity, oxidative stress, and biomaterial–cell interaction research at INSERM U1026 Biotis, Bordeaux, France under Marie Skłodowska-Curie Fellowship (Horizon 2020).
ISO 10993-1:2025 Expert
Deep knowledge of the 2025 revision — lifecycle approach, explicit benefit-risk determination, test waiver justification, and legacy BEP/BER gap analysis. I build documentation designed to support first-pass review readiness.
