Two terms, side by side

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

Regulatory

EU Medical Device Regulation(MDR)

In one line

Regulation (EU) 2017/745 governing medical devices in the European Union.

Definition

Regulation (EU) 2017/745 (MDR) lays down rules concerning the placing on the market, making available, and putting into service of medical devices for human use and accessories, replacing the previous Medical Devices Directive (MDD).

Why it matters

MDR introduces stricter clinical evidence requirements, stronger post-market surveillance, UDI, EUDAMED registration, and an enhanced role for Notified Bodies. Many devices have undergone reclassification, especially software.

Regulatory

EU In Vitro Diagnostic Regulation(IVDR)

In one line

Definition

Why it matters

IVDR significantly expanded the scope of devices requiring Notified Body involvement and tightened performance evaluation, post-market performance follow-up, and transparency requirements.

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.

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.
