Basics of Medical Device Design Controls: What, Why, and How ELIQUENT Life Sciences Blog

design control

It is the systematic application of management policies, procedures, and practices to the tasks of identifying, analyzing, controlling, and monitoring risk. It should be used early and throughout the design and development process and often generates new information that needs to be fed back into the design and development process. Again, all of these outputs must be verified against applicable design inputs. The finished design output documentation is the basis for your device master record (DMR). A traceability matrix is an invaluable tool to show a high-level view and the flow of medical device product development from beginning to end. Ask an experienced medical device product development project manager about how much time was spent keeping traceability up to date throughout a project.

Design Inputs become a roadmap for the product developer

Both the ISO standard and the FDA legislation define design practice requirements for medical devices and have converged over the years. Each manufacturer of any class III or class II device...shall establish and maintain procedures to control the design of the device in order to ensure that specified design requirements are met. But each requirement is actually a part of a dynamic process that can change and repeat. Design Controls should be a systematic way to demonstrate the progress of your medical device product development efforts. Plus, unless you are tackling medical device product development solo, you have other people working with you who should help define Design Inputs. How many Design Reviews does your medical device product development project need?

CFR - Code of Federal Regulations Title 21

Enhanced content is provided to the user to provide additional context. In comparing the two primary strategies —FDA and ISO — there are key points developers need to understand. Firstly, FDA provides requirements for Design Controls under 21CFR820.30 and the ISO Standard lists requirements under ISO Section 7 (Product Realization). See how we partner with many quality and manufacturing trade associations. Go to market with MasterControl, a manufacturing industry leader. Join us at our can’t-miss annual event for life sciences quality and manufacturing professionals.

When you first start implementing Design Controls, there are a lot of complex issues that you’ll need to tackle.

Keep the DHF separate from project file

And as your project progresses, you’ll soon find using these general-purpose tools take days, if not weeks, to properly update and maintain your traceability matrix. Yes, there are parts of the FDA regulations and ISO requirements that do apply to you, even if you are pre-market. Confirm that the completed design validation did not leave any unresolved discrepancies. Logging for timber is a pretty destructive process and you’re going to run out of easily accessible trees pretty quickly. You can move a logging camp for free, but even then you’ll still run out of trees eventually.

If you’re unsure when or how to start, then it may benefit you to ask an expert for help. Starting with a strong Design Controls procedure and system can save headaches down the road. Services like Qualio Plus feature a team of experts that can advise you on Design Controls and the entire FDA approval process. Using a DHF Index to guide the reader through the records that make up the DHF is, without question, a far more effective way to present this complex compilation of records.

The approval, including the date and signature of the individual(s) approving the requirements, shall be documented. Each manufacturer shall establish and maintain plans that describe or reference the design and development activities and define responsibility for implementation. The plans shall identify and describe the interfaces with different groups or activities that provide, or result in, input to the design and development process. The plans shall be reviewed, updated, and approved as design and development evolves.

Verifying the Final Medical Device Design

For medical device startups, the quality system expectations are that you have all parts and pieces defined and implemented by the time you go to market. Design controls demonstrate our medical devices are safe, effective, and meet the indications for use. Prior to founding Greenlight Guru, I was fortunate to have played a part in getting 40+ medical devices through regulatory clearance in a variety of different roles. In more specific terms, Design Verification is in place to ensure that the design output can consistently meet the design input. Here, objective evidence, such as test reports, is often necessary to confirm that the device is able to satisfy the design input.

The form and organization of the planning documents are less important than their content and should be customized for each company. Remember that as development progresses, the planning documents should be updated. Design changes is the process by which changes to design are identified and documented.

Specifically, this is the time in your medical device project when you should put together your FDA 510(k) submission (provided this is your path to market clearance). Design Inputs become a roadmap, or set of “directions”, that a medical device product developer uses to design and develop a product. Design Reviews are also a time in a project to bring the team together in order to scrutinize and evaluate the state of the medical device and ensure that what needs to be done has been addressed.

Review the records of one design review and confirm that the review included an individual without direct responsibility for the design stage being reviewed. Also, confirm that outstanding action items are being resolved or have been resolved. Determine if design validation was accomplished using initial production devices or their equivalents. As previously noted, design validation includes the requirement for software validation. If the selected device is software controlled its software must be validated.

When you have an idea for a medical device that you want to turn into an actual product, you will follow some sort of product development process. And I highly encourage you to map your product development process and WRITE IT DOWN. The best practices of medical device product development have a good flow between Design Controls and Risk Management. I will share with you why Design Controls even matter and how they will help you during your medical device product development. At that time the FDA Design Controls regulations were still fairly new -- not only to me -- but the industry in general. ISO and corresponding design and development requirements for the medical device industry were also very new to the industry in the late 90s.

If you build a forester’s hut (2 timber), though, a family assigned there will plant trees. Those trees take a while to grow — they’re trees, after all — but pairing a forester’s hut with a logging camp can actually provide a steady (if slow) and renewable supply of timber. Development points are a reward you’ll get as your town reaches certain milestones — building five burgage plots, upgrading two of those five to Level 2 burgage plots, and so on.
