“Learn how FDA Design Controls ensure the safety and quality of medical devices. BioBoston Consulting guides manufacturers in implementing design controls for effective compliance and improved product outcomes.” 

Design Controls are the foundation that assists a manufacturer in creating safe, reliable, and ever-evolving medical devices to better serve healthcare professionals and patients with unmet needs. With these controls in place, manufacturers can tackle the challenges of medical device development, minimize risks and maximize product quality — thus influencing the future of healthcare products. 

The medical device field is a critical aspect of contemporary medicine providing engineers numerous opportunities to create new and beneficial therapies for countless diseases that impact the quality of life worldwide. Nevertheless, the creation and execution of such medical devices needs to be systematic in nature to guarantee their safety, efficacy, and quality. In order to enforce these standards and protect the public health, the Food and Drug Administration (FDA) has created an extensive system of regulations governing the design, manufacture, and distribution of medical devices in this country. 

One of the key elements of Part 820 is Subpart C – Design Controls, an essential part of the framework that regulates the design and development activities for medical devices. The purpose of Design Controls is to create a systematic way to ensure devices are made safely and effectively as well as improve compliance with regulation. These controls allow manufacturers to navigate the complexities surrounding medical device design and development, from risk management through delivery of products that meet the needs of healthcare professionals and patients. 

Understanding the Scope 

FDA Design Controls apply to all class III or class II device manufacturers and some class I devices are also subject to this regulation. One exception to the design control requirement for automated Class I devices that are computer software and ones listed in Section 820.30(a)(2)(ii) in the designated device sections of this part. 

Design Control: How to do it Right 

Creating Design and Development Plans: The very first step in the implementation of design controls is to create and communicate appropriate plans that describe the supporting design and development activities. These plans should detail what group is responsible for ensuring the implementation of any plan and will also specify interfaces with groups or activities that provide input to the design and development process or affected by it. The plans, that are developed and that change over time with the design must be reviewed and approved on a regular basis. 

Design Input: Manufacturers should establish and maintain procedures needed to ensure that design requirements relating to a medical device are appropriate and in line with the intended use of the device. This includes thinking of the needs associated with users and patients. Scheduling should be based on the availability of a team that is strategically distributed across the functional groups mentioned above – so that any ambiguous, conflicting or incomplete requirement can be resolved in hours (max 1-2 working days).  

Approval of Design Input Requirements: All design input requirements should be documented and approved by designated individuals for the approval process. 

Design Output: This involves setting up processes that define and document the design output. The design output should be presented in such a way that its conformity to design input requirements can be adequately evaluated. These procedures should incorporate or reference acceptance criteria, and make sure that design outputs essential for the proper functioning of a device are identified. Release of design output must be documented, reviewed, and approved as appropriate; and the signatures and dates should be documented. 

Design Review: Documented reviews of the design outputs must be planned and conducted at appropriate stages of the device’s design development. Reviews shall include all possible representatives from functional aspects and a person(s) without direct responsibility to the design stage under review. Experts also need to join in if it is justified. Results of design reviews—each design that was reviewed, the date of the review, and who participated in the review must be recorded with other Design History File (DHF) records. 

Design Verification: Manufacturers are required to establish procedures to ensure that the device design verifies that the design output meets the design input requirements for the device. DHF must include the results from this verification process, such as design identification methods used and dates of the work along with who verified it. 

It involves Design validation to be conducted with defined operating conditions and on first production units, lots or batches. The aim is to ensure that the devices meet specified user requirements and intended uses under actual or simulated use conditions. Similar to verification on the design side, all results of validation must be contained in the DHF. 

Design transfer: Procedures should be defined to ensure the device design is correctly interpreted into production specifications. This is an important step to ensure that what is designed will match exactly with the manufactured product. 

Design Changes: The design control procedures should contain the provisions for identifying, documenting, validating or verifying as appropriate reviewing, and approving design changes before the change is implemented. Necessary design modifications are important to ensure the safety and functionality of the device. 

Design History File: Finally, manufacturers must create and maintain a DHF that covers each individual type of device. This file shall include or cite all the records needed to prove that the design complies with both the approved design plan and this regulation. 

Why You Should Implement Design Controls? 

In the medical device industry, we often see that the implementation of robust design controls is key. Such controls are required for a systematic and standard approach to design and development of safe and effective medical devices by manufacturers. Subpart C – Design Controls, follow the FDA standards that help manufacturers significantly reduce rapid design errors and enhance product quality while streamlining regulatory compliance. 

Benefits of Design Controls 

Improved Quality of Product: By identifying and rectifying the design problems in earlier stages of product development, design controls help to improve overall quality and reliability of products. This reduces the chances of device breakdowns or recalls, as a result helping patients and manufacturers. 

Opportunity to Reduce Risk: Design controls enable comprehensive risk analysis and risk assessment during the design stage. Early recognition and avoidance of potential risks can prevent adverse events with subsequent impact on patient safety. 

Adherence to Regulatory Requirements: As mentioned above, compliance with FDA Quality System Regulation and design control requirements will keep a manufacturer in regulatory compliance which then aids in getting new medical devices approved and cleared. 

Optimal Use of Resources: Design controls result in a streamlined design and development process that can help ensure resources are used optimally. Identifying possible problems earlier empowers manufacturers to evade expensive redesigns as well as faster overall development time and costs. 

Continuous improvement: A culture of continuous improvement can be sustained through regular design reviews and documentation in the Design History File. Manufacturers can utilize historical projects for assessments of improvement and apply learnings to future designs. 

The struggle within-design controls (Implementation) 

Design controls offer many advantages, but there are challenges in implementing them for medical device manufacturers: 

Lack of Resources:

Limited resources often may prevent small and medium-sized manufacturers from deploying more robust design controls. To ensure compliance is achieved, all necessary resources ought to be allotted. 

Nature of Engineering:

Numerous medical devices are complicated in nature, which leads to several components being stressed together with all their functions. This can make it challenging to ensure that all design input requirements are sufficiently addressed. 

Even though things are continuing to move along from the standpoint of regulatory update, Manufacturers need to view to any changes in regulations and changing their design control procedure for an outcome. The design team needs to be constantly monitored and trained for this. 

It is Essential to Reflect:

Implementing design controls requires effective communication and collaboration between different departments and stakeholders. It breaks the design development when there is a miscommunication or different silos approach. 

Conclusion

For medical device manufacturers, it is critical to implement design controls established in the FDA’s Quality System Regulation within their QMS. Subpart C shows how a manufacturer can deliver devices that conform to the design requirements and meet user and patient needs at the highest levels of quality to ensure safety and effectiveness in medical device products on the market. A strong and well-documented Design History File (DHF) is crucial for proving compliance with the regulation as well as aiding the FDA regulators in their review process. Not only does embracing design controls contribute to improved product quality, but it also creates a culture of ongoing improvement, innovation and advancement in the medical device industry.
