Understanding Intended Purpose – A Critical Element for Medical Devices and IVDs in the EU
The intended purpose of a medical device or in vitro diagnostic device (IVD) is a fundamental concept in EU regulations. It plays a crucial role in device classification, conformity assessment, and ensuring safety and performance. This article explores what the intended purpose means, why it’s important, and how manufacturers should define it under the EU Medical Device Regulation (MDR) and In Vitro Diagnostic Medical Device Regulation (IVDR).
What is Intended Purpose?
The MDR and IVDR define intended purpose as “the use for which a device is intended according to the data supplied by the manufacturer on the label, in the instructions for use or in promotional or sales materials or statements and as specified by the manufacturer in the clinical evaluation” (MDR Article 2(12), IVDR Article 2(12)).
In simpler terms, it’s a comprehensive description of what the device is designed to do, who should use it, for whom, and under what circumstances.
Main Challenges of creating the right Intended Purpose
1 Striking the right balance of specificity: The intended purpose needs to be specific enough to clearly define the device’s use, but not so narrow that it unduly limits legitimate uses or requires frequent updates.
2. Consistency across documentation: Ensuring the intended purpose is consistently described across all relevant documents (labeling, instructions for use, technical files, clinical evaluation, etc.) can be challenging.
3. Anticipating foreseeable uses: Manufacturers need to consider and address all reasonably foreseeable uses of the device, including potential misuse, which can be difficult to predict.
4. Avoiding overly broad claims: There’s a temptation to make the intended purpose as broad as possible, but manufacturers must avoid claims that cannot be substantiated by clinical evidence.
5. Addressing multiple components: For complex devices or systems, clearly articulating the intended purpose for each component while maintaining a coherent overall statement can be challenging.
6. Keeping up with technological advancements: As technology evolves, especially in areas like software and AI, defining the intended purpose in a way that remains relevant can be difficult.
7. Aligning with classification rules: The intended purpose directly impacts device classification, so crafting it to accurately reflect the device’s risk class while meeting business objectives can be challenging.
8. Addressing different user groups: Clearly defining the intended users, their required skills, and the target patient population in a comprehensive yet concise manner can be complex.
9. Regulatory variations: While trying to maintain a globally consistent intended purpose, addressing slight variations in regulatory requirements across different markets can be challenging.
10. Regular review and updates: Ensuring the intended purpose remains current and accurate throughout the device lifecycle, and managing any necessary updates, can be an ongoing challenge.
Key Components of Intended Purpose
An intended purpose statement should typically include:
– Medical function (e.g. diagnosis, treatment, monitoring)
– Specific medical condition or disease addressed
– Intended user (e.g. healthcare professional, patient)
– Target patient population
– Use environment (e.g. hospital, home)
– For IVDs: analyte to be detected, specimen types
Importance of Intended Purpose
The intended purpose is critical because it:
– Determines device classification and applicable regulatory requirements
– Guides the clinical evaluation or performance evaluation process
– Informs the risk management process
– Sets the boundaries for device marketing and promotion
– Provides essential information for users in the labeling and instructions for use
Defining Intended Purpose: Key Considerations
When defining the intended purpose, manufacturers should:
– Be specific and clear to avoid ambiguity
– Consider all reasonably foreseeable uses of the device
– Avoid overly broad claims that cannot be substantiated
Checklist of Defining an Intended Purpose:
Regulatory Requirements
The intended purpose must be clearly stated in:
– Device labeling and instructions for use (MDR Annex I Section 23.1, IVDR Annex I Section 20.1)
– Technical documentation (MDR Annex II Section 1.1, IVDR Annex II Section 1.1)
– Clinical evaluation or performance evaluation documentation
– EU declaration of conformity
Conclusion
Defining a clear and comprehensive intended purpose is not just a regulatory requirement—it’s a fundamental step in ensuring the safety and effectiveness of medical devices and IVDs. By carefully considering and articulating the intended purpose, manufacturers can better navigate the regulatory landscape, manage risks, and ultimately provide safer and more effective products for patients and healthcare providers.
For manufacturers, investing time and effort in crafting a precise intended purpose statement is an essential part of bringing a medical device or IVD to market in the EU. It sets the foundation for regulatory compliance and helps ensure that devices are used safely and effectively for their intended purposes.
