Submitting a medical device to the FDA can feel like navigating a maze. Even the most seasoned teams can overlook a small detail that derails the entire process, delaying market access by months.
Medical device submission errors are more common than you might think, and they can cost you both time and money. The stakes are high, especially when regulatory delays can impact product launches and business growth. But the good news? These mistakes are preventable.
So, how do you make sure your next submission doesn’t fall into the same trap? Stick with us. You’re about to discover some of the main pitfalls you definitely want to avoid and the strategies that will help you get it right the first time.
1. Incomplete or incorrect documentation
First and foremost, missing documentation is the #1 reason submissions get rejected. The FDA requires complete technical documentation, including device descriptions, testing data, clinical performance, labeling, and manufacturing information. Without it, your application can be flagged with a Refuse to Accept (RTA) notification, delaying or halting your submission.
To prevent this, create a comprehensive checklist of every document the FDA expects. In addition, working with a regulatory expert can help you identify gaps you might miss internally.
2. Device misclassification
Another common pitfall is choosing the wrong device classification. The FDA places devices into Class I (low risk), Class II (moderate risk), or Class III (high risk) categories. Each classification determines which regulatory pathway you need to follow, such as 510(k), De Novo, or PMA.
If you misclassify your device, you may end up submitting the wrong type of application or omitting required information. To avoid this, carefully review the FDA’s official device classification guidelines and align your device with the proper classification before moving forward.
3. Poor risk management files
Risk management is more than a box to check; it’s a critical part of ensuring patient safety and regulatory compliance. The FDA expects your risk management file to follow ISO 14971 standards, which outline how you should identify hazards, assess risks, and document mitigation efforts.
Weak or incomplete risk files raise red flags with FDA reviewers. Therefore, begin your risk assessment early in product development and continue updating it throughout the device’s lifecycle. The FDA will want to see robust risk assessments that identify hazards, evaluate risks, and detail mitigation strategies.
Start your risk analysis early and integrate it throughout the product lifecycle to strengthen your submission.
4. Ignoring FDA guidance updates
Did you know FDA regulations and guidance are constantly evolving? That’s why submitting outdated information or failing to comply with current standards is a common pitfall.
To stay ahead, regularly review updates on the FDA Medical Devices page and adjust your submission strategy to meet the latest standards.
5. Skipping pre-submission communication
In many cases, companies skip the optional Pre-Sub meeting with the FDA, which is a free, voluntary meeting where you can present your device and submission strategy to FDA reviewers. This session helps identify gaps early and clarifies expectations directly from the agency.
Instead, take advantage of the Pre-Sub program to validate your strategy, address potential regulatory concerns, and gain valuable feedback before your official submission.
6. Inconsistent performance testing data
Beyond documentation, performance testing data must also be complete and consistent. The FDA expects detailed protocols, raw data, and statistical analyses that follow recognized standards. If your data is missing or inconsistent, reviewers may request additional testing, which could increase costs and delay your submission.
To avoid this, ensure your performance testing data is clearly organized, aligned across documents, and thoroughly validated from the start.
7. Overlooking usability and human factors
In addition to functionality, your device must be safe and easy to use. The FDA requires evidence that risks related to user errors have been addressed through human factors and usability engineering.
Neglecting this step can result in safety concerns and may slow down or prevent approval. To stay on track, plan usability studies early and document how findings are integrated into your product development and risk files.
8. Insufficient software validation and cybersecurity planning
If your device includes software, the FDA will expect a high standard of validation and cybersecurity preparedness. This means demonstrating compliance with recognized frameworks like IEC 62304 and documenting your software development lifecycle.
Overlooking this area can raise major concerns. To minimize risk, ensure your software and cybersecurity documentation is complete, tested, and compliant with the relevant requirements.
9. Marketing claims that don’t match your submission
What you promote publicly must reflect what you submitted to the FDA. If your marketing materials include exaggerated or unsupported claims, the FDA may flag them as misleading. This can damage your credibility and even result in sanctions.
To avoid problems, make sure your marketing content is aligned with your approved indications for use and is backed by sufficient evidence.
10. Weak document control and inconsistent messaging
Even with strong content, poor document control can hold you back. The FDA looks for consistency across all documents, especially when it comes to your device’s “Indications for Use.” Any discrepancies between your 510(k) summary, product labeling, and cover letter may cause confusion and slow down the review.
To keep everything aligned, implement a solid Quality Management System (QMS) and maintain strict version control across your documentation.
11. Gaps in shelf-life and stability testing
Finally, your claims around shelf life must be backed by science. Submitting insufficient or incomplete shelf-life data raises concerns about how your device performs over time. The FDA expects both real-time and accelerated stability studies to support the duration you claim.
To meet these expectations, plan your studies early and include robust, reliable data that shows your product will remain safe and effective throughout its lifecycle.
