One of the most expensive questions in implantable device development is also one of the most frequently answered too quickly: Do we need an implantation study? The reflex answer — "it's an implant, so yes" — has led to a lot of unnecessary animal studies and a lot of unnecessary cost. The correct answer depends on your specific device, your materials, your existing data, and how you've structured your overall biological evaluation under ISO 10993-1:2025. ISO 10993-6:2026, th

Choosing the wrong implant test site is one of the more avoidable mistakes in biocompatibility study design and one of the more consequential ones. If your test doesn't reflect how the device actually contacts tissue in clinical use, your data may not support the conclusions you need, and FDA reviewers will notice. Under ISO 10993-6:2026, the test sample must be implanted into or onto the tissues most relevant to the intended clinical use of the material. The choice of tissue

Medical device risk management is the systematic application of management policies, procedures, and practices to identify, evaluate, control, and monitor risks throughout the device lifecycle. Under the QMSR and ISO 14971:2019, risk management isn't a one-time premarket activity—it's an ongoing process integrated with design controls, biocompatibility evaluation, and quality system operations. For manufacturers navigating regulatory requirements in 2026, effective risk manag

Biocompatibility testing for medical devices has fundamentally changed under ISO 10993-1:2025. The familiar endpoint matrix that automatically prescribed which tests to conduct based on device contact type and duration no longer exists. Instead, manufacturers must conduct systematic biological risk assessment to determine when biocompatibility testing is necessary, which tests are appropriate, and how to justify those decisions scientifically. For medical device manufacturers

Biocompatibility is straightforward at its core: your device materials must not cause an unacceptable biological response in the body under their intended use conditions. In practice, that means you need to understand how your device contacts the body, for how long, what biological hazards exist, and how you'll demonstrate that biological risks are acceptable. What FDA Biocompatibility Requirements Actually Cover FDA uses biocompatibility evaluation to judge whether your devi

On April 23, 2026, the Centers for Medicare & Medicaid Services (CMS) and the FDA announced the Regulatory Alignment for Predictable and Immediate Device (RAPID) coverage pathway, a groundbreaking initiative designed to accelerate Medicare beneficiary access to FDA-designated Breakthrough Devices. Combined with the expanding Total Product Life Cycle Advisory Program (TAP), these programs fundamentally change how manufacturers should approach development strategy, evidence gen

Contract research organizations occupy a unique position in the medical device ecosystem. While CROs don't typically hold FDA establishment registrations as manufacturers, the quality of services they provide directly impacts their clients' QMSR compliance, biocompatibility evaluations, and regulatory submissions. The QMSR's emphasis on process-based quality management, expanded FDA inspection authority, and integration of biocompatibility with design controls creates both ch

ISO 10993-1 sits at the center of how regulators expect you to think about biological safety. It is the international standard for biological evaluation of medical devices, and Part 1 provides the framework for structuring your entire biocompatibility strategy within a risk management process. The 2025 edition, represents the most significant change to biocompatibility evaluation in decades. The familiar endpoint matrix that guided testing decisions for over 30 years has been

The QMSR became effective February 2, 2026, replacing 21 CFR Part 820 as the foundation for medical device quality systems in the United States. While the two-year transition period allowed manufacturers to prepare, many organizations are still working to fully align their quality systems with QMSR requirements and ISO 13485:2016 expectations. Whether you're just beginning your transition or refining an implementation already underway, a systematic roadmap helps you priorit

Biocompatibility evaluation sits at the intersection of product safety, regulatory compliance, and quality system management. Under the QMSR , which incorporates ISO 13485:2016 by reference, biocompatibility must be fully integrated into your quality management system—not treated as a standalone testing exercise conducted outside your design and risk management processes. The publication of ISO 10993-1:2025 adds complexity and opportunity. The new standard's risk-based biol
