Device Classification Workflow

Classify device under MDR Annex VIII:

1. Identify device duration (transient, short-term, long-term)
2. Determine invasiveness level (non-invasive, body orifice, surgical)
3. Assess body system contact (CNS, cardiac, other)
4. Check if active device (energy dependent)
5. Apply classification rules 1-22
6. For software, apply MDCG 2019-11 algorithm
7. Document classification rationale
8. Validation: Classification confirmed with Notified Body

Classification Matrix

Factor	Class I	Class IIa	Class IIb	Class III
Duration	Any	Short-term	Long-term	Long-term
Invasiveness	Non-invasive	Body orifice	Surgical	Implantable
System	Any	Non-critical	Critical organs	CNS/cardiac
Risk	Lowest	Low-medium	Medium-high	Highest

Software Classification (MDCG 2019-11)

Information Use	Condition Severity	Class
Informs decision	Non-serious	IIa
Informs decision	Serious	IIb
Drives/treats	Critical	III

Classification Examples

Example 1: Absorbable Surgical Suture

• Rule 8 (implantable, long-term)
• Duration: > 30 days (absorbed)
• Contact: General tissue
• Classification: Class IIb

Example 2: AI Diagnostic Software

• Rule 11 + MDCG 2019-11
• Function: Diagnoses serious condition
• Classification: Class IIb

Example 3: Cardiac Pacemaker

• Rule 8 (implantable)
• Contact: Central circulatory system
• Classification: Class III

Technical Documentation

Prepare technical file per Annex II and III:

1. Create device description (variants, accessories, intended purpose)
2. Develop labeling (Article 13 requirements, IFU)
3. Document design and manufacturing process
4. Complete GSPR compliance matrix
5. Prepare benefit-risk analysis
6. Compile verification and validation evidence
7. Integrate risk management file (ISO 14971)
8. Validation: Technical file reviewed for completeness

Technical File Structure

ANNEX II TECHNICAL DOCUMENTATION
├── Device description and UDI-DI
├── Label and instructions for use
├── Design and manufacturing info
├── GSPR compliance matrix
├── Benefit-risk analysis
├── Verification and validation
└── Clinical evaluation report

GSPR Compliance Checklist

Requirement	Evidence	Status
Safe design (GSPR 1-3)	Risk management file	☐
Chemical properties (GSPR 10.1)	Biocompatibility report	☐
Infection risk (GSPR 10.2)	Sterilization validation	☐
Software requirements (GSPR 17)	IEC 62304 documentation	☐
Labeling (GSPR 23)	Label artwork, IFU	☐

Conformity Assessment Routes

Class	Route	NB Involvement
I	Annex II self-declaration	None
Is/Im	Annex II + IX/XI	Sterile/measuring aspects
IIa	Annex II + IX or XI	Product or QMS
IIb	Annex IX + X or X + XI	Type exam + production
III	Annex IX + X	Full QMS + type exam

Clinical Evidence

Develop clinical evidence strategy per Annex XIV:

1. Define clinical claims and endpoints
2. Conduct systematic literature search
3. Appraise clinical data quality
4. Assess equivalence (technical, biological, clinical)
5. Identify evidence gaps
6. Determine if clinical investigation required
7. Prepare Clinical Evaluation Report (CER)
8. Validation: CER reviewed by qualified evaluator

Evidence Requirements by Class

Class	Minimum Evidence	Investigation
I	Risk-benefit analysis	Not typically required
IIa	Literature + post-market	May be required
IIb	Systematic literature review	Often required
III	Comprehensive clinical data	Required (Article 61)

Clinical Evaluation Report Structure

CER CONTENTS
├── Executive summary
├── Device scope and intended purpose
├── Clinical background (state of the art)
├── Literature search methodology
├── Data appraisal and analysis
├── Safety and performance conclusions
├── Benefit-risk determination

Post-Market Surveillance

Establish PMS system per Chapter VII:

1. Develop PMS plan (Article 84)
2. Define data collection methods
3. Establish complaint handling procedures
4. Create vigilance reporting process
5. Plan Periodic Safety Update Reports (PSUR)
6. Integrate with PMCF activities
7. Define trend analysis and signal detection
8. Validation: PMS system audited annually

PMS System Components

Component	Requirement	Frequency
PMS Plan	Article 84	Maintain current
PSUR	Class IIa and higher	Per class schedule
PMCF Plan	Annex XIV Part B	Update with CER
PMCF Report	Annex XIV Part B	Annual (Class III)
Vigilance	Articles 87-92	As events occur

PSUR Schedule

Class	Frequency
Class III	Annual

Class IIb	Every 2 years
Class IIa	When necessary

Serious Incident Reporting

Timeline	Requirement
2 days	Serious public health threat
10 days	Death or serious deterioration
15 days	Other serious incidents

EUDAMED and UDI

Implement UDI system per Article 27:

1. Obtain issuing entity code (GS1, HIBCC, ICCBBA)
2. Assign UDI-DI to each device variant
3. Assign UDI-PI (production identifier)
4. Apply UDI carrier to labels (AIDC + HRI)
5. Register actor in EUDAMED
6. Register devices in EUDAMED
7. Upload certificates when available
8. Validation: UDI verified on sample labels

EUDAMED Modules

Module	Content	Actor
Actor	Company registration	Manufacturer, AR
UDI/Device	Device and variant data	Manufacturer
Certificates	NB certificates	Notified Body
Clinical Investigation	Study registration	Sponsor
Vigilance	Incident reports	Manufacturer
Market Surveillance	Authority actions	Competent Authority

UDI Label Requirements

Required elements per Article 13:

• UDI-DI (device identifier)
• UDI-PI (production identifier) for Class II+
• AIDC format (barcode/RFID)
