Two terms, side by side

Pick any two terms to see definitions, context, pitfalls, and sources in parallel.

Regulatory

Abbreviated 510(k)

In one line

510(k) variant that relies on FDA guidance, special controls, or recognized consensus standards.

Definition

An Abbreviated 510(k) uses summary reports of compliance with relevant FDA guidance documents, special controls, or recognized consensus standards in lieu of submitting full underlying test data.

Why it matters

Useful for well-understood device types where standards substantially cover safety and performance. Reviewers still expect summary information demonstrating conformance.

Regulatory

Special 510(k)(Special 510(k))

In one line

Streamlined 510(k) for modifications to a manufacturer's own legally marketed device.

Definition

A Special 510(k) relies on design control procedures to support a determination of substantial equivalence for changes to the submitter's own predicate, with a target FDA review goal of 30 days.

Why it matters

Best when the modification's effects can be assessed via verification and validation methods with well-established performance criteria. Not appropriate for changes to indications for use.

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.
