The Association for the Advancement of Medical Instrumentation (AAMI) develops and publishes consensus standards (often as ANSI/AAMI/ISO or ANSI/AAMI/IEC) covering medical device performance, sterilization, and human factors. AAMI develops many US consensus standards for devices, including sterilization, cybersecurity and health technology management. Several AAMI standards are FDA-recognized. It also offers training and certification for professionals.

Why it matters

AAMI is the U.S. partner for adopting ISO and IEC medical device standards. ANSI/AAMI/ISO 14971 (risk), ANSI/AAMI/IEC 62304 (software), and ANSI/AAMI/IEC 60601 (electrical safety) are core MedTech standards.

Common pitfalls

•Manufacturers might incorrectly assume that adherence to an AAMI standard alone guarantees regulatory approval, overlooking country-specific deviations or additional requirements.
•Failing to regularly check for updated versions of AAMI standards can lead to non-compliance as regulatory expectations evolve.
•Misinterpreting the scope of an AAMI standard can lead to inadequate testing or documentation for certain aspects of a medical device.
•Over-reliance on AAMI standards without considering the unique risks and characteristics of a specific device can result in an incomplete risk management process.

Why compare MedTech terms side by side?

MedTech terminology is full of pairs that look interchangeable but carry very different regulatory, clinical, and commercial consequences. Picking the wrong framework, pathway, or standard early in a project can add months to a submission, invalidate clinical evidence, or trigger an audit finding. Side-by-side comparison is the fastest way to surface those differences before they become costly mistakes.

Each comparison on this page pulls from the same vendor-neutral, sourced definitions used throughout the MedTech Terms glossary. You see the one-line summary, the formal definition, why it matters in practice, common pitfalls, and the primary sources (FDA guidance, EU MDR/IVDR articles, ISO/IEC standards, MDCG documents, IMDRF principles) that back each entry. That makes the comparison defensible in regulatory strategy memos, design reviews, and submission narratives.

Common comparison patterns

Regulatory pathway choice - 510(k) vs PMA, 510(k) vs De Novo, Abbreviated vs Special 510(k).
Quality systems - QSR vs ISO 13485, QMSR vs QSR.
Software classification - SaMD vs SiMD, Locked vs adaptive AI.
EU frameworks - MDR vs IVDR, CE Mark vs UKCA.
Cybersecurity artifacts - SPDX vs CycloneDX SBOM, CVE vs CVSS.
Post-market actions - Recall vs field action, Removal vs correction.
