Intended Use and Its Key Elements (Indications, Intended Purpose & Contraindications)

In the medical device regulatory ecosystem, “Intended Use”—also referred to as Intended Purpose in the EU MDR—forms the cornerstone of how a device is understood, classified, and evaluated by regulators. Across global frameworks, the concept remains consistent:

• FDA (21 CFR 801 & 21 CFR 860) defines intended use as the general purpose of the device or its function, including the medical conditions it is meant to diagnose, treat, cure, mitigate, or prevent.
• EU MDR (Regulation (EU) 2017/745) describes intended purpose as the use for which a device is intended according to the manufacturer’s instructions, labeling, and promotional materials.
• CDSCO (India's Medical Device Rules, 2017) follows the same foundation, requiring manufacturers to state the specific purpose, clinical benefits, and conditions of use in labeling and regulatory submissions.

Although wording varies slightly, the core requirement is universal: the manufacturer must clearly define what the device is meant to do, for whom, and under what conditions.

A precisely written Intended Use is not just a technical detail—it is the central element that determines the entire regulatory strategy of a medical device. It directly influences:

• Device classification and risk categorization
• Regulatory pathway and submission requirements (510(k), PMA, EU MDR CE marking, CDSCO Form MD-14/MD-22, MD-07/03 etc.)
• Risk management under ISO 14971
• Labeling, Instructions for Use (IFU), and promotional claims
• Clinical evaluation and clinical evidence requirements
• Performance testing and safety validation
• Software validation and SaMD categorization
• Post-market surveillance and vigilance obligations

Because of this, every aspect of a device’s safety, performance, and compliance ultimately traces back to a clear and consistent Intended Use statement. A poorly worded or overly broad intended use can lead to regulatory rejection, additional testing, misclassification, or even safety risks. In contrast, a well-defined intended use aligns the device’s design, evidence, labeling, and market positioning into one cohesive and compliant framework.
