Device Classification Workflow
Classify device under MDR Annex VIII:
- Identify device duration (transient, short-term, long-term)
- Determine invasiveness level (non-invasive, body orifice, surgical)
- Assess body system contact (CNS, cardiac, other)
- Check if active device (energy dependent)
- Apply classification rules 1-22
- For software, apply MDCG 2019-11 algorithm
- Document classification rationale
- 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:
- Create device description (variants, accessories, intended purpose)
- Develop labeling (Article 13 requirements, IFU)
- Document design and manufacturing process
- Complete GSPR compliance matrix
- Prepare benefit-risk analysis
- Compile verification and validation evidence
- Integrate risk management file (ISO 14971)
- Validation: Technical file reviewed for completeness

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 | ☐ |

| 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:
- Define clinical claims and endpoints
- Conduct systematic literature search
- Appraise clinical data quality
- Assess equivalence (technical, biological, clinical)
- Identify evidence gaps
- Determine if clinical investigation required
- Prepare Clinical Evaluation Report (CER)
- 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) |
