Advertising rules & permitted/prohibited claims
Regulatory basis - MDR Art. 7 (claims); MDR Art. 2(24) (intended purpose shaped by advertising); IVDR Art. 7 (IVDR claims). Advertising and promotional materials are part of the "information supplied by the manufacturer" and shape the legal intended purpose of the device.
Annex IX — QMS + Technical Documentation Assessment
MDR 2017/745, Annex IX and IVDR 2017/746, Annex IX. Annex IX is the most widely used conformity assessment route for Class IIa, IIb, III (MDR) and Class B, C, D (IVDR). It is the only permitted route for Class III (MDR) and Class D (IVDR).
Annex X — EU type examination
MDR 2017/745, Annex X and IVDR 2017/746, Annex X. Annex X defines the EU type examination procedure. It is used in combination with Annex XI (Part A or B) and is available for Class IIa, IIb (MDR) and Class B, C (IVDR). Not available for Class III (MDR) or Class D (IVDR), which must use Annex IX.
Annual reports & PSUR
Regulatory basis - MDR Art. 85 / IVDR Art. 80. The PSUR is required for higher-risk device classes and must be submitted to the notified body via EUDAMED. MDCG 2022-21 provides detailed guidance on PSUR content and format.
Authorised representatives (EU REPs)
EU REP obligations are defined in MDR Article 11 and IVDR Article 11. Definitions appear in MDR Article 2(32) and IVDR Article 2(29).
Borderline & combination products
Borderline product guidance is primarily in MDCG 2022-5. Drug-device combinations are addressed in MDR Art. 1(8)–(9), MDR Annex I §12.2, and relevant EMA guidance. ATMP combination products are governed by Regulation (EC) No 1394/2007.
Chapter I — General requirements
MDR 2017/745, Annex I, Chapter I (GSPR 1–5) and equivalent provisions in IVDR 2017/746, Annex I, Chapter I. These requirements are foundational — they apply to every device regardless of type or class.
Chapter II — Design & construction
MDR 2017/745, Annex I, Chapter II (GSPR 6–22) and equivalent provisions in IVDR 2017/746, Annex I, Chapter II. These are specific technical requirements for how devices must be designed and manufactured.
Chapter III — IFU & labelling
MDR 2017/745, Annex I, Chapter III, Section 23 and IVDR 2017/746, Annex I, Chapter III, Section 20. These are the labelling and IFU requirements as part of the GSPR. Post-market labelling obligations are covered separately in Labelling & advertising.
Class A · B · C · D — IVDR classes
IVDR 2017/746, Article 47 and Annex VIII. IVDR replaced the old IVDD framework (List A / List B / General Devices) with a risk-based four-class system reflecting the risk posed by the diagnostic information generated.
Classification rules 1–7
IVDR 2017/746, Annex VIII. Seven rules classify IVDs based on the risk posed by the diagnostic information they generate, the severity of conditions they detect, and the vulnerability of the populations they serve.
Companion diagnostics
IVDR Art. 2(7) (definition); IVDR Art. 48(3) (mandatory EMA/NCA consultation); IVDR Annex VIII Rule 2 (Class C minimum for companion diagnostics). Companion diagnostics require mandatory coordination between the IVDR pathway and the pharmaceutical regulatory pathway.
Competent authority-initiated actions
Regulatory basis - MDR Art. 93–97 / IVDR Art. 88–92. National competent authorities have broad powers to investigate, restrict, and remove medical devices from the EU market. The European Commission can intervene at EU level where national actions are insufficient.
Conformity assessment — overview & route selection
MDR conformity assessment procedures are set out in MDR Art. 52 and Annexes IX–XI. IVDR equivalents are in IVDR Art. 48 and Annexes IX–XI. The EU Declaration of Conformity is required under MDR Art. 19 / IVDR Art. 17 and MDR Annex IV / IVDR Annex IV.
Design & manufacturing information
MDR Annex II, Section 3 and IVDR Annex II, Section 3. This section of the technical documentation covers how the device was designed and how it is manufactured — the information necessary to ensure reproducibility and traceability.
Device description & specification
MDR Annex II, Section 1 and IVDR Annex II, Section 1. The device description and specification is the foundational section of technical documentation — it defines what the device is, what it does, and for whom.
Device registration & UDI upload
Regulatory basis - MDR Art. 28–29 / IVDR Art. 25–26. Manufacturers must register all devices placed on the EU market in EUDAMED, linked to the Basic UDI-DI. Registration is a prerequisite for placing the device on the market within the applicable class timelines.
Distribution records
Regulatory basis - MDR Art. 10(8) / IVDR Art. 10(8) — manufacturers must maintain records that allow identification of all customers who received a device, enabling effective recalls and FSCAs. Importers and distributors have parallel obligations under MDR Art. 13(5) and Art. 14(5).
Distributors
Distributor obligations are defined in MDR Article 14 and IVDR Article 14. Definitions appear in MDR Article 2(34) and IVDR Article 2(31).
Economic operator registration (SRN)
Regulatory basis - MDR Art. 30 / IVDR Art. 27. All manufacturers, EU authorised representatives, importers, and (in some cases) distributors must register as economic operators in EUDAMED and receive a Single Registration Number (SRN).
EU Declaration of Conformity & CE marking
MDR Art. 19 and Annex IV (Declaration of Conformity); MDR Art. 20 (CE marking). Equivalent IVDR provisions: Art. 17 and Annex IV (DoC); Art. 18 (CE marking).
EUDAMED registration — overview
Regulatory basis - MDR Art. 28–33 / IVDR Art. 25–30. EUDAMED is the European database on medical devices — the central information infrastructure underpinning MDR and IVDR. Manufacturers, EU REPs, importers, and distributors must all register as economic operators.
EUDAMED UDI registration
Regulatory basis - MDR Art. 27(3)–(4) and Art. 28–29 / IVDR Art. 24(3)–(4) and Art. 25–26. Manufacturers must register their devices in EUDAMED using the UDI as the primary identifier before placing devices on the EU market.
EUDAMED vigilance module
Regulatory basis - MDR Art. 92 and Art. 100–105 / IVDR Art. 87 and Art. 97–102. EUDAMED is the central EU information system for medical devices, including the vigilance module for reporting serious incidents and FSCAs.
Field safety notices (FSNs)
Regulatory basis - MDR Art. 89(3) / IVDR Art. 84(3). A field safety notice (FSN) is the communication issued by a manufacturer to inform customers, distributors, and users of an FSCA and what action they need to take. MDCG 2023-3 provides a template.
Glossary of key terms
MDR (Regulation (EU) 2017/745) and IVDR (Regulation (EU) 2017/746) — terms are drawn from official definitions in Article 2 of each regulation unless otherwise noted.
GSPR checklist & compliance
Both MDR 2017/745 and IVDR 2017/746. The GSPR checklist (cross-reference table) is a mandatory component of the technical documentation under Annex II of both regulations.
GSPR cross-reference
MDR Annex II, Section 4 and IVDR Annex II, Section 4. The GSPR cross-reference table is a mandatory component of technical documentation linking each applicable general safety and performance requirement to the evidence of conformity.
How classification works
MDR classification rules are in Annex VIII of MDR 2017/745. IVDR classification rules are in Annex VIII of IVDR 2017/746. Classification determines the conformity assessment route, notified body involvement, and post-market obligations.
How to report — national competent authorities
Regulatory basis - MDR Art. 87 / IVDR Art. 82 require reports to be submitted to the NCA of the member state(s) where the incident occurred. EUDAMED is the primary reporting platform; some NCAs also accept or require national-format reports.
Implementing acts, delegated acts & harmonised standards
The legislative framework beneath MDR and IVDR comprises implementing acts (Commission), delegated acts (Commission), Common Specifications (Commission via implementing act), and harmonised European standards (CEN/CENELEC under Commission mandate).
Importers
Importer obligations are defined in MDR Article 13 and IVDR Article 13. Definitions appear in MDR Article 2(33) and IVDR Article 2(30).
IVDR Annexes — all 16
Annexes I–XVI of Regulation (EU) 2017/746 (IVDR). The IVDR annexes mirror the MDR structure with adaptations for the in vitro diagnostic context.
Labelling requirements
Regulatory basis - MDR Annex I §23 / IVDR Annex I §20 (GSPR labelling requirements); MDR Art. 10(11) (labelling obligations on manufacturers). Language requirements vary by member state. Post-market labelling obligations extend to maintaining current labelling as the device and evidence evolve.
Legacy & grandfathered devices
MDR Art. 120 (transitional provisions for MDD/AIMDD devices); IVDR Art. 110 (transitional provisions for IVDD devices); Regulation (EU) 2023/607 (amended MDR transitional dates); Regulation (EU) 2024/1860 (amended IVDR transitional dates).
Lifecycle of a medical device
MDR (Regulation (EU) 2017/745) and IVDR (Regulation (EU) 2017/746)
Manufacturers
MDR Article 10 and IVDR Article 10 set out the general obligations of manufacturers. Definitions appear in MDR Article 2(30) and IVDR Article 2(27).
Market surveillance & enforcement — overview
Regulatory basis - MDR Art. 93–97 / IVDR Art. 88–92. Market surveillance is the system of NCA activities that ensures devices on the EU market comply with MDR/IVDR requirements. It is distinct from — but complementary to — the manufacturer's own post-market surveillance system.
MDR vs IVDR — which applies?
Regulatory basis - MDR = Regulation (EU) 2017/745 | IVDR = Regulation (EU) 2017/746. Both regulations are mutually exclusive — a product is governed by one or the other, never both simultaneously.
Near-patient & self-test IVDs
IVDR Art. 2(4)–(5) (definitions); IVDR Annex VIII Rules 6–7 (classification impact of self-test and near-patient format); IVDR Annex I §20 (GSPR for near-patient and self-test devices). Self-test IVDs are generally upward-classified and face additional usability requirements.
Non-EU & third-country access
Both MDR 2017/745 and IVDR 2017/746. This section covers requirements for non-EU manufacturers placing devices on the EU market, EU REP obligations, and how EU MDR/IVDR relates to non-EU regulatory systems.
Overview — Annex I (GSPR)
Both MDR 2017/745 and IVDR 2017/746. Each regulation contains its own Annex I (GSPR), with mostly parallel structure and some IVDR-specific elements.
Overview & ongoing obligations
Both MDR 2017/745 and IVDR 2017/746. Post-market obligations begin the moment a device is placed on the market and continue until the device is withdrawn from service.
Performance evaluation (Annex XIII)
IVDR Art. 56 and Annex XIII. Performance evaluation for IVDs is the IVDR equivalent of clinical evaluation under MDR. It is mandatory for all IVD classes and must be maintained as a continuous lifecycle process.
Performance studies (IVDR)
IVDR Art. 57–77 and Annex XIV. Performance studies are studies conducted on specimens from human subjects specifically to evaluate the performance of an IVD. They have their own regulatory framework distinct from MDR clinical investigations.
Person responsible for regulatory compliance (PRRC)
The PRRC requirement is established in MDR Article 15 and IVDR Article 15.
PMS requirements by class
Regulatory basis - MDR Art. 83–86 / IVDR Art. 78–81. PMS is a proactive, systematic process that all manufacturers must implement. The depth and reporting frequency scale with device risk class.
Post-market data in technical documentation
MDR Annex III and IVDR Annex III define the post-market technical documentation requirements. Key documents are the PMS plan, PMS report / PSUR, and PMCF plan and evaluation report (MDR) or PMPF plan and evaluation report (IVDR).
Recalls — classification & coordination
Regulatory basis - MDR Art. 89 and Art. 95 / IVDR Art. 84 and Art. 90. EU medical device recalls are a subset of FSCAs. Unlike some other regulatory systems, the EU does not have a single standardised recall classification system — instead, the risk assessment under ISO 14971 and NCA discretion determine the urgency and scope.
Recent amendments & corrigenda
MDR 2017/745 and IVDR 2017/746 and their amending regulations. This page tracks significant amendments; always verify current status in the Official Journal.
Reclassification & SCENIHR opinions
MDR Art. 51(2) and IVDR Art. 47(2) empower the European Commission to reclassify devices or device categories by implementing act. Scientific opinions informing reclassification were historically provided by SCENIHR (now replaced by SAG-MD and the MDCG).
Regulation (EU) 2017/746 — IVDR key articles
The full text of IVDR 2017/746 is available in the Official Journal: OJ L 117, 5.5.2017, p. 176–332. All article references on this site refer to the IVDR as amended, including Regulation (EU) 2022/112 and Regulation (EU) 2024/1860.
Regulatory framework overview
Both MDR 2017/745 and IVDR 2017/746
Reporting timeframes
Regulatory basis - MDR Art. 87(5)–(8) / IVDR Art. 82(5)–(8). Timeframes run from the date the manufacturer becomes aware of the incident. EUDAMED is the reporting platform for EU vigilance reports.
Risk management (ISO 14971)
Risk management is required by GSPR §1 and §2 of MDR Annex I and IVDR Annex I. The harmonised standard EN ISO 14971:2019 provides the implementation framework and creates a presumption of conformity with the relevant GSPR when applied.
Serious incidents & near-misses
Regulatory basis - MDR Art. 2(65) and Art. 87 / IVDR Art. 2(67) and Art. 82. The definitions of serious incident and near-miss determine the scope of mandatory vigilance reporting.
Software & SaMD classification
MDR software classification is governed by Annex VIII, Rule 11 of MDR 2017/745. IVDR software follows the same class assignment rules as other IVDs under IVDR Annex VIII. MDCG 2021-24 provides authoritative guidance on MDR Rule 11 application.
Software as a Medical Device (SaMD)
MDR Art. 2(1) (software included in definition); MDR Annex VIII Rule 11 (classification); MDR Annex I §17 and §21 (GSPR for software). MDCG 2019-11 and MDCG 2021-24 provide detailed guidance. For IVD software: IVDR Annex VIII Rules 1–7.
Technical documentation — overview
MDR 2017/745, Annex II (technical documentation) and Annex III (technical documentation on post-market surveillance). Equivalent provisions in IVDR 2017/746, Annex II and III. Technical documentation must be compiled before CE marking and maintained throughout the device lifecycle.
Transitional provisions & timelines
MDR (Regulation (EU) 2017/745) and IVDR (Regulation (EU) 2017/746)
UDI labelling requirements
Regulatory basis - MDR Art. 27(4)–(6) / IVDR Art. 24(4)–(6) and MDR Annex VI Part C / IVDR Annex VI Part C. These provisions specify where and how the UDI carrier must appear on device labelling.
UDI overview & structure
Both MDR 2017/745 and IVDR 2017/746. UDI requirements are set out primarily in MDR Art. 27 / IVDR Art. 24 and MDR Annex VI / IVDR Annex VI.
UDI-DI & UDI-PI explained
Regulatory basis - MDR Annex VI Part B and C and IVDR Annex VI Part B and C. The UDI consists of a Device Identifier (UDI-DI) and a Production Identifier (UDI-PI). Understanding the distinction is fundamental to UDI system compliance.
Using international clinical data
Both MDR 2017/745 and IVDR 2017/746. International clinical data — generated outside the EU — can be used in clinical evaluations and performance evaluations, subject to certain conditions.
What is an IVD?
Regulatory basis - This page is based on Article 2(2) of Regulation (EU) 2017/746 (IVDR). The IVD definition determines whether a product is governed by IVDR rather than MDR.
What is not a medical device?
Regulatory basis - Exclusions from the MDR are set out primarily in Article 1(5) and 1(6) of Regulation (EU) 2017/745. Equivalent IVDR exclusions appear in Article 1(4) and 1(5) of Regulation (EU) 2017/746.
What must be reported
Regulatory basis - MDR Art. 87 and IVDR Art. 82 define the reporting obligations for serious incidents and field safety corrective actions. Manufacturers must report to the National Competent Authority of the member state(s) where the incident occurred or the FSCA is being taken.
When an FSCA is required
Regulatory basis - MDR Art. 2(68) and Art. 89 / IVDR Art. 2(70) and Art. 84. An FSCA is any corrective action taken by a manufacturer to reduce a risk of death or serious deterioration in health associated with a device already placed on the market. FSCAs must be notified to NCAs.
Who needs to comply?
MDR (Regulation (EU) 2017/745) and IVDR (Regulation (EU) 2017/746)
