Introduction

In the highly regulated world of Medical Technology and Pharmaceuticals, precision is not just a goal—it is a legal and safety requirement. As systems become more software-intensive and integrated, the overlap between engineering, clinical validation, and regulatory compliance (FDA, EMA, ISO) creates a complex web of terminology.

Whether you are developing Class III medical devices or managing large-scale pharmaceutical lifecycles, understanding these core concepts is the first step toward achieving seamless certification and operational excellence. This glossary serves as a foundational reference for professionals navigating the rigorous standards of the Life Sciences industry.

1. Regulatory Standards & Compliance

• ISO 13485: The international standard that specifies requirements for a Quality Management System (QMS) specific to the medical device industry.
• IEC 62304: A functional safety standard that monitors safe design and maintenance of medical device software. It introduces life cycle requirements for MedTech software.
• FDA 21 CFR Part 11: Regulations that set forth the criteria under which electronic records and electronic signatures are considered trustworthy, reliable, and equivalent to paper records.
• EU MDR (Medical Device Regulation): The current regulatory framework for medical devices in the European Union, emphasizing stricter clinical data and post-market surveillance.
• GAMP 5 (Good Automated Manufacturing Practice): A risk-based approach to compliant GxP computerized systems, widely used in the pharmaceutical industry to ensure software quality.

2. Product & Software Categories

• SaMD (Software as a Medical Device): Software intended to be used for one or more medical purposes that perform these purposes without being part of a hardware medical device.
• SiMD (Software in a Medical Device): Software that helps run the hardware of a medical device (embedded software).
• Combination Products: Products comprised of two or more regulated components (e.g., a drug and a device, or a device and a biological product) that are combined as a single entity.

3. Risk & Quality Engineering

• ISO 14971: The key standard for the application of risk management to medical devices. It defines how to identify, estimate, and evaluate hazards.
• FMEA (Failure Mode and Effects Analysis): A systematic technique for failure analysis to identify potential failure modes within a system and their impact on the patient or user.
• Post-Market Surveillance (PMS): A collection of processes used by manufacturers to monitor the performance of a medical device after it has been released to the market.
• Design History File (DHF): A compilation of records which describes the design history of a finished medical device, essential for FDA audits.

4. Traceability & Data Integrity

• End-to-End Traceability: The ability to link a high-level clinical requirement to its specific software code, risk analysis, and final validation test.
• ALCOA+: A set of principles (Attributable, Legible, Contemporaneous, Original, Accurate, etc.) used to ensure data integrity in the pharmaceutical and medical device sectors.
• V-Model: A graphical representation of the systems development lifecycle where for every development phase, there is a corresponding testing phase.
