Manufacturers must navigate complex approval processes across different global markets. A central concept in many regulatory pathways is the use of predicate devices.
Understanding how to effectively leverage predicate devices and adhere to applicable medical device standards is essential for streamlining submissions and gaining market access efficiently.
This guide explores what predicate devices are, how they’re used in major regulatory regions, the role of standards in these processes, and how technology is transforming predicate selection and submission preparation.

Understanding Predicate Devices in the Regulatory Landscape
A predicate device is a previously approved medical device that serves as a benchmark to demonstrate that a new device is substantially equivalent in terms of safety and effectiveness. This concept is especially relevant in the FDA 510(k) process but has equivalents in other regulatory jurisdictions.
The rationale is straightforward: if a new device is shown to be similar to a legally marketed device, the regulatory burden can be reduced. This process expedites access to the market while also maintaining public safety.
In addition to predicate devices, adherence to international standards (such as those developed by ISO, IEC, or the GHTF) helps demonstrate compliance with essential safety and performance requirements. Aligning product development and documentation with these standards enhances regulatory acceptance and reduces review time.
What is a Predicate Device?
A predicate device helps determine whether a new device can follow a streamlined regulatory pathway. In the U.S., a 510(k) submission requires the manufacturer to prove substantial equivalence to a predicate, meaning:
- The same intended use
- Similar or same technological characteristics
- Or, if different, that any changes do not raise new questions of safety or effectiveness
Manufacturers must provide clear evidence, including comparative data, technical documentation, and possibly benches or clinical studies, depending on the risk level. Globally, the predicate device definitions carry slightly, but the general concept is the same: reduce redundant evaluation by comparing new products to existing, approved ones.
Understanding how predicate devices relate to regulatory compliance for medical devices is foundational to creating an effective global regulatory strategy.
Global Overview: Predicate Pathways by Region
FDA 510(k) Process (United States)
In the U.S., the 510(k) pathway remains one of the most widely used methods for market entry.
There are three types of 510(k) submissions:
- Traditional 510(k): A full comparison to a predicate device.
- Special 510(k): For modifications made by the original manufacturer.
- Abbreviated 510(k): Leverages consensus standards and guidance.
Substantial equivalence (SE) is the core requirement, manufacturers must provide evidence that their device matches or improves upon a predicate device without compromising safety or efficacy. Standards like IEC 60601, ISO 14971, and ISO 10993 often support the safety and performance claims, enabling a faster FDA review.
MDR and Equivalence Claims (European Union)
Under the EU MDR (Medical Device Regulation), manufacturers cannot rely on predicate devices in the same way as the U.S. Instead, equivalence claims are made under Article 61 during clinical evaluation.
Three core criteria must be met:
- Same clinical condition and intended purpose
- Similar technology
- Equivalent performance and safety
Unlike the FDA, the EU requires access to technical documentation for the device being referenced, making it challenging for third-party equivalence claims. However, using harmonized standards supports conformity with essential MDR requirements.
Health Canada’s Framework (Canada)
Health Canada also considers predicate-like submissions, especially for Class III and IV medical devices. These pathways are not identical to the U.S. 510(k) process but still allow manufacturers to use comparative evidence from similar marketed devices to reduce regulatory burden.
Manufacturers must align with recognized standards, such as CAN/CSA or international equivalents, to prove safety and effectiveness.
TGA Conformity Assessment (Australia)
Australia’s TGA (Therapeutic Goods Administration) requires manufacturers to meet Essential Principles for safety and performance, often supported by standards and clinical evidence. Predicate devices can be referenced in clinical evaluations, especially when used to justify the absence of new clinical trials.
However, the regulatory emphasis remains on meeting performance standards rather than formal predicate equivalence.
Other Key Markets (Brazil, Japan, and China)
- Brazil (ANVISA) allows local predicate comparisons with a focus on product classification and clinical evaluation.
- Japan (PMDA) permits referencing approved devices but requires extensive documentation in Japanese.
- China (NMPA) has a similar process, but with stricter local clinical data requirements and fewer accepted foreign predicates.
Manufacturers must align with local technical standards while leveraging equivalence when possible.
The Role of Standards and Guidance Documents
Medical device standards provide a consistent framework for proving safety and performance. Whether you’re referencing ISO 13485 for quality systems or IEC 60601 for electrical safety, aligning with international medical device standards can support claims of equivalence and simplify global submissions.
Key advantages of using standards include:
- Predictability: Regulators are familiar with well-known standards.
- Efficiency: Reduces the need for redundant testing.
- Documentation support: Standards align with technical file expectations.
In many regions, referencing recognized or harmonized standards offers a presumption of conformity, making your regulatory review more straightforward.
Selecting the Right Predicate Device
Choosing the right predicate device is a key step in any regulatory submission. A poor match can delay approval or result in rejection.
To avoid setbacks, use the FDA’s 510(k) database to find recently cleared devices (within 5-7 years) that closely match your product’s intended use and technology. Ensure the predicate has a solid safety record and accessible documentation.
Small differences can raise new safety concerns, potentially requiring additional clinical data. A careful, strategic selection helps streamline the review process and improves your chances of success.
Key Considerations for Manufacturers Using Predicate Devices Globally
When developing a global regulatory submission strategy, keep in mind:
- Not all jurisdictions accept U.S. predicate logic
- Documentation access (especially in the EU) can be restrictive
- Clinical evidence requirements vary so plan for data reuse across markets
- Avoid assumptions because predicate acceptance in one country doesn’t mean automatic approval in another.
Global alignment requires careful planning and coordination of clinical, technical, and regulatory documents.
How Technology Can Help
Technology is playing a growing role in simplifying regulatory processes for medical device manufacturers. AI-driven tools and regulatory intelligence platforms are making it easier to identify suitable predicate devices and prepare stronger, more efficient submissions.
Predicate device software can quickly analyze similarities between devices, helping teams select the most appropriate match. Regulatory intelligence platforms provide up-to-date insights on evolving global standards and requirements, reducing the risk of non-compliance.
AI is also used to detect potential risks and highlight missing or weak areas in documentation. By automating these tasks, technology reduces humane error, shortens submission timelines, and frees regulatory teams to focus on strategic planning and decision making, ultimately helping to bring devices to market faster.
Conclusion
Navigating global medical device regulations requires more than technical expertise. It demands a deep understanding of predicate devices, medical device standards, and submission strategy.
By choosing the right predicate device, aligning with global standards, and leveraging new technologies, manufacturers can accelerate time-to-market and avoid regulatory setbacks.
