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

Software Classification (MDCG 2019-11)

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

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

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
└── PMCF plan summary

Qualified Evaluator Requirements

• Medical degree or equivalent healthcare qualification
• 4+ years clinical experience in relevant field
• Training in clinical evaluation methodology
• Understanding of MDR requirements

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

Serious Incident Reporting

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

UDI Label Requirements

Required elements per Article 13:

• UDI-DI (device identifier)
• UDI-PI (production identifier) for Class II+
• AIDC format (barcode/RFID)
• HRI format (human-readable)
• Manufacturer name and address
• Lot/serial number
• Expiration date (if applicable)
