1. Master Your Predicate Device Selection

The foundation of every successful 510(k) submission lies in selecting the appropriate predicate device. Remember that substantial equivalence is based primarily on two key factors:

  • Intended use: How the device will be used in clinical practice
  • Technological aspects: The design, materials, and operating principles.

When selecting your predicate device, thoroughly understand your intended claims and carefully study your competitors.

Ask yourself:

  • What specific functions do you want your product to perform?
  • What claims do you want to make about it?
  • What similar products exist in the market and how are they being used?
  • What post-market data is available for these devices, including information from TPLC and MAUDE databases?

Don't limit your research to marketing materials alone. Take the time to review previous submissions for your intended predicate by examining 510(k) summaries posted by FDA, 510(k) Statements (which can be requested), information available through FOIA requests, and FDA reviewer notes.

Whenever possible, we suggest obtaining samples of potential predicate devices for side-by-side testing with your product. This direct comparison can provide extremely data for your submission.

2. Consider Using Reference Devices

Sometimes, your device may have significant technological differences from available predicates. If so, consider including reference devices in your submission, particularly when:

  • There are meaningful technology differences between your predicate and subject device.
  • Your proposed testing methodology is more similar to a reference device than the predicate.
  • Specific use conditions align more closely with a reference device.
We've found that reference devices can greatly strengthen your submission by providing additional points of comparison, especially for novel features or technologies that aren't fully represented in your primary predicate.

3. Plan to Engage with the FDA Early Through Pre-Submissions

The pre-submission process (or "pre-sub") offers an invaluable—and surprisingly underutilized—opportunity to receive FDA feedback before committing to your full submission strategy.

Always initiate a pre-sub, especially when:

  • You're unsure about predicate device selection.
  • Your device has significant differences from the chosen predicate.
  • Your testing plan will deviate from established guidance or standards.
  • You need feedback on a worst-case scenario rationale.

Early interaction with FDA reviewers can help identify potential issues before they become roadblocks, align expectations, and possibly streamline the formal review process later.

4. Explore Special Designation Programs When Applicable

For qualifying devices, the FDA offers accelerated pathways that can expedite the review process.

The Breakthrough Devices Program is appropriate if your device:

  • Provides more effective treatment or diagnosis of life-threatening or irreversibly debilitating conditions (and)
  • Represents breakthrough technology, addresses unmet needs, offers significant advantages over existing alternatives, or its availability is in patients' best interest.

The Safety and Performance Based Pathway (STeP) may be suitable if your device:

  • Significantly improves the benefit-risk profile through safety enhancements.
  • Reduces the occurrence of serious adverse events, known failure modes, or use-related hazards.
  • Improves the safety profile of other devices or interventions.

These programs can provide increased opportunities for FDA interaction and potentially faster reviews.

5. Conduct Thorough Testing and Present Data Effectively

Comprehensive performance testing is essential for demonstrating substantial equivalence. 

Make sure your testing:

  • Addresses all aspects of your device's functionality.
  • Follows recognized standards and guidelines.
  • Includes appropriate controls and comparisons.
  • Provides statistical analysis where relevant.

When presenting test data in your submission, always make sure to include clear summaries explaining why the results are relevant to safety and effectiveness. Use tables, flowcharts, and illustrations to make complex information easily digestible for reviewers.

6. Pay Attention to Submission Logistics

The technical content of your submission is crucial, but don't overlook the logistical elements that can impact review efficiency:

  • Before assembling your submission, thoroughly review the eSTAR template.
  • Address every section of the template, even if only to provide a rationale for why it's not applicable.
  • Format your submission for readability and ease of navigation.
  • Include summaries of data that clearly explain relevance to safety and effectiveness.
  • Use visual aids like tables, flowcharts, and illustrations to clarify complex information.
  • Review all attachments to ensure they're complete, legible, and relevant.
  • Have an independent expert review the submission before finalization.
  • Verify that your user fee has been paid correctly.

A well-organized submission demonstrates professionalism and respect for reviewers' time, potentially facilitating a smoother review process.

7. Anticipate and Address Potential Questions

Put yourself in the reviewer's position and anticipate questions or concerns they might have about your device or testing approach. Proactively addressing these points in your submission can prevent delays associated with additional information requests.

For each claim or statement, ask yourself:

  • Is this supported by adequate data?
  • Have I explained how this data applies to my specific device?
  • Have I addressed obvious comparisons to the predicate?
  • Have I explained any deviations from standards or guidance documents?

8. Develop a Comprehensive Regulatory Strategy

Your 510(k) submission should be part of a broader regulatory strategy that considers:

  • Product lifecycle management
  • Future iterations and modifications
  • Potential expansion to new indications
  • International regulatory requirements
  • Postmarket surveillance plans

This strategic approach ensures your submission aligns with long-term business objectives and prepares you for regulatory obligations beyond initial clearance.

9. Build a Strong Regulatory Team

Whether in-house or through consultants, ensure your regulatory team has:

  • Direct experience with 510(k) submissions in your device category
  • Understanding of relevant standards and guidance documents
  • Technical knowledge of your device technology
  • Strong writing and communication skills
  • Attention to detail

The right expertise can make the difference between a straightforward review and a prolonged, challenging process.

10. Learn from Every Interaction with the FDA

Each submission and FDA interaction provides valuable insights for future regulatory efforts:

  • Document reviewer feedback and questions.
  • Analyze successful submissions to identify effective approaches.
  • Share learnings across your organization.
  • Stay current with FDA guidance updates and policy changes.
  • Consider how reviewer trends might impact future submissions.

This continuous learning approach helps refine your regulatory strategy over time and builds institutional knowledge that benefits all future submissions.
