510(k) Predicate Device Search & Substantial Equivalence (SE) Table
Identifying an appropriate predicate device is an important part of preparing a US FDA 510(k) premarket notification. A well-supported predicate search helps establish the regulatory context for your device and supports the substantial equivalence assessment.
Cosmetic Compliance Nest provides predicate device research and a structured Substantial Equivalence (SE) comparison table to help medical device businesses organise relevant regulatory information and prepare for the next stages of their 510(k) submission.
What Is a Predicate Device?
A predicate device is a legally marketed device that may be used as a comparison reference in a 510(k) submission. The proposed device must demonstrate substantial equivalence to an appropriate predicate based on its intended use and relevant technological characteristics, including applicable differences and performance considerations.
Choosing a predicate requires more than finding a device that looks similar. Its regulatory status, intended use, indications for use, technological characteristics and available supporting information should be carefully reviewed.
What Is Included in This Service?
- Predicate device research: Research into potentially relevant legally marketed devices using available FDA resources and other relevant public information.
- Regulatory information review: Review of available details such as device name, manufacturer, 510(k) number, product code and classification information, where available.
- Intended use comparison: Assessment of relevant intended use and indications for use information.
- Technological characteristics comparison: Organisation of relevant design, operating principle, materials, features and technology information based on the details available.
- SE comparison table: A structured table comparing the proposed device with one or more potential predicate devices.
- Difference identification: Highlighting of identified differences that may require further explanation, testing or supporting documentation.
- Documentation gaps: Notes on information that may be needed to strengthen the substantial equivalence rationale.
What Is an SE Table?
A Substantial Equivalence (SE) table presents a side-by-side comparison of the proposed device and a potential predicate device. It helps organise key similarities and differences and supports the explanation of why the proposed device may be substantially equivalent.
Depending on the device, the comparison may cover:
- Intended use and indications for use
- Device design and operating principle
- Technological characteristics
- Materials and patient-contacting components, where relevant
- Performance specifications and test methods
- Software, electrical or other technical features, where applicable
- Identified differences and the rationale for addressing them
Why Choose Predicate Device Research?
- Organise publicly available regulatory information in one place.
- Develop a clearer understanding of potentially relevant predicate devices.
- Identify important similarities and differences early in the preparation process.
- Support planning for performance testing and technical documentation.
- Improve the structure and traceability of your substantial equivalence rationale.
Our Process
- Device information collection: We review the proposed device description, intended use, indications for use and available technical documentation.
- Predicate search: We research potentially relevant devices using available regulatory databases and public records.
- Candidate assessment: We compare the available regulatory and technical information to identify potentially suitable candidates for further review.
- SE table preparation: We organise the comparison and record identified differences and information gaps.
- Deliverable review: We provide the prepared research and comparison document for your review and further regulatory planning.
Who Can Benefit From This Service?
- Medical device manufacturers preparing for a US FDA 510(k) submission
- Start-ups assessing the regulatory pathway for a new device
- Companies developing modified or updated medical devices
- Regulatory affairs professionals organising predicate research
- Businesses seeking an initial comparison before investing in further testing or submission preparation
