FDA Design Controls: What Medical Device Makers Need to Know
Building a medical device that works is only half the job. You also have to prove that it does what it’s meant to do, and that it does so safely and reliably. That’s where FDA design controls come in. They give manufacturers a clear, structured way to manage the design and development process, catch problems early, and stay compliant from the first concept to the finished product.
What the FDA Expects
Design and development requirements now fall under the FDA’s Quality Management System Regulation (QMSR), which took effect on February 2, 2026. The QMSR incorporates ISO 13485:2016 by reference, including the design and development requirements in Clause 7.3. If you haven’t already, now is a good time to check that your quality management system covers them.
The Core Design Control Activities
Here’s what it looks like in practice:
- Design planning: Decide how development will unfold: the stages, who is responsible for what, and how reviews will be handled.
- Design inputs: Write down what the product needs to do, including its intended use, safety expectations, and performance criteria.
- Design outputs: Keep the specifications, drawings, and manufacturing information that turn those requirements into a real product.
- Design reviews: Pause at planned points to check progress and spot design problems before they become expensive.
- Verification and validation: Verification confirms that your outputs meet your inputs. Validation confirms that the finished device actually meets user needs and its intended use.
- Design changes: Review, document, and approve every change before it goes into effect.
The Paperwork That Backs It All Up
Keep a Design and Development File that pulls everything together: plans, inputs, outputs, review records, verification results, validation evidence, and change records. If an inspector asks how you got from idea to finished device, this file is your answer.
Why It’s Worth Getting Right
Solid design controls lower development risk, improve product quality, and make regulatory inspections far less stressful. Regulations evolve, so it’s also smart to review your procedures regularly and keep them current.
