## Overview

IEC 62304 medical device software lifecycle framework. Software safety classification (Class A/B/C), design control, verification, validation, and regulatory documentation for FDA and EU MDR submissions.

## Software Safety Classification

- **Class A** -- No injury or damage to health (e.g., log viewer)
- **Class B** -- Non-serious injury (e.g., infusion pump alarm)
- **Class C** -- Death or serious injury (e.g., radiation therapy planning)

## Key Processes

- **Design Control** -- Requirements -> Design -> Implementation -> Verification -> Validation
- **Risk Management (ISO 14971)** -- Hazard identification, risk estimation, risk control
- **Software Change Management** -- Change classification (bug fix, enhancement, new feature)
- **Problem Resolution** -- CAPA for software defects
- **Cybersecurity** -- Threat modeling, vulnerability management
