Memorable Quotes

1. Mike Drues: "If the FDA doesn’t understand your device, it’s not their fault—it’s the manufacturer’s responsibility to communicate effectively."
2. Etienne Nichols: "Uncertainty in your device description leads to questions, delays, and potential rejection."
3. Mike Drues: "A picture’s worth a thousand words, but a video is worth a thousand pictures—use it to demonstrate your device clearly."

Key Takeaways

MedTech Trends

1. Clear communication is essential in the increasingly complex regulatory environment, especially with AI and software-based devices.
2. Ambiguity in device descriptions can lead to unnecessary testing or inappropriate classification.
3. Visual aids, like images and videos, are becoming standard tools to enhance submissions.

Practical Tips

1. Test your description’s efficacy by asking someone unfamiliar with the device to explain it back to you.
2. Write layered descriptions—simple overviews for general audiences and detailed appendices for specialists.
3. Incorporate visuals or videos to clarify complex mechanisms or testing processes.

Future Questions

1. How might advancements in AI reshape the expectations for device descriptions?
2. Could the FDA eventually require interactive or multimedia submissions as standard?
3. What new tools or technologies can help manufacturers streamline the description-writing process?

MedTech 101: Device Descriptions

What is a device description?

A section of your regulatory submission detailing what your device is, how it works, and its intended use. It includes:

• Anatomy: Components and materials.
• Physiology: Function and mechanism of action (MOA).
• Pathology: Risks or potential failures.

Why it matters:

• Guides regulatory classification and testing requirements.
• Establishes a clear understanding for reviewers, ensuring smooth approval processes.
