The U.S. Food and Drug Administration continues to provide avenues for medical device manufacturers to get their products approved and put on the market faster. Some examples of some agency initiatives are:

• New 510(k) pathway- A regulatory pathway that allows medical devices to get their final guidance based upon safety and performance criteria.
• 21st Century Cures Act - This Act was passed in 2016 and is intended to accelerate the development of medical products and provide new advances for patients.
• Breakthrough devices Program - Voluntary program to help patients with life-threatening and irreversible conditions.

The FDA is working to lessen the regulatory burden on sponsors. However, devices must go through the regulatory process to be approved for the market. In addition, it can take a long time to get from product concept to product release. Therefore, it is important to understand the FDA submission and product development processes.

Product development is about coordinating complex systems and processes.

• Design control.
• Compliance Management
• Assessment and risk analysis.
• Design.
• Validation of the process

Software-based medical devices are more difficult to design because of the likelihood of functionality discrepancies or defects occurring later in production. Therefore, it is crucial that the software code delivered to the device can be used as intended.

How can you ensure that your medical device is safe and meets all regulatory requirements? First, it's important to understand regulators' expectations regarding how you should develop and implement design controls. You will eventually need to transfer product design to manufacturing while following regulatory guidelines. Finally, it would be best if you designed it for compliance.

Design Control includes a Closer Examination of R&D Data

The FDA's "Design Control Guidance for Medical Device Makers" states that medical device design starts with the approval and development of design inputs and the associated manufacturing processes.

Design controls are a set of interrelated practices and procedures that are integrated into the design and development process. They are also known as checks and balances. Design controls are an integral part of development. They allow for systematic evaluation of the design.

To get a medical device on the market and approved, it is necessary to have a robust and efficient process. It must also consider the complexity and potential risk of the product. The sections below, which use the 21 CFR Part 802.30 guidelines as a reference point, highlight the design control regulations.

Documentation

All information regarding medical device design and development must be documented and traceable. Every word of research data, storyboards and functional specifications, emails and minutes of meetings, and notes written on whiteboards must be recorded in system records accessible to all stakeholders and inspectors.

Design Development and Planning

The manufacturer should prepare and document plans that outline or refer to the design and development activities and the responsibility for their implementation. As the product's design develops, stakeholders should approve and review the plans.

Design Verification

Design verification is necessary to ensure that the design output meets design input requirements. The design history file (DHF) contains the design identification, dates, methods, and names of those who performed the verification.

Design Validation

Design validation ensures that the device meets defined user requirements and is suitable for intended uses. This includes the testing of units in real or simulated usage conditions. In addition, design control must include valid validation of research and design (R&D) data to ensure that the device meets its original design requirements.

Design Transfer

Manufacturing specifications should ensure that devices can be consistently and reliably manufactured within the product and process capabilities. Manufacturers must establish procedures to ensure that the device's design is accurately translated into production specifications.

Design Updates

A well-known fact of medical-device-design life is that designs will change. Therefore, companies operating in highly regulated environments must have a proper change management process. The guidelines require manufacturers to create procedures to identify, document, validate, verify, review, approve, and implement design changes.

What Inspectors See For

Design control is one of the Quality System Inspection Technique's (QSIT) subsystems. FDA uses this technique to increase efficiency in inspection processes.

The investigator is responsible for reviewing product designs. They will assess whether the device has been designed, validated, and met users' needs. Also, they will need to determine if any design changes have been made and assessed before implementation. Here are some items that inspectors should have access to when evaluating design controls:

• DHF includes inputs and outputs, verification, validation, and transfer.
• Design reviews, design matrix, failure mode analysis, design risk analysis (FMEA), design review.
• Design changes

FDA's "Guide to Inspections of Quality Systems" guides FDA staff during inspections. Below are some excerpts from the guide to help you get an idea of how to prepare:

• As a guide, use the design plan of the firm to help you choose the right design project.
• Consider reviewing the software validation part of the project before proceeding to the assessment and design control system.
• When assessing the firm's design control system, evaluate the firm's risk analysis. The design plan should include risk analysis and be considered during the entire design process.
• Validation and verification activities must be predictive. Acceptance criteria should be clearly stated upfront. Examine the documentation that is associated with both validation and verification activities.
• Determine if design reviews were conducted. Designers should be able to give feedback on any emerging or existing problems and assess the design's progress. The design review should also confirm that the design is ready for the next phase. The design's ability to be produced and whether it meets the input requirements should be the focus of the reviews.
• Verify that the design was properly transferred. The design and implementation plan must include the transfer process. Production specifications are typically written documents like assembly drawings, inspection and testing specifications, and manufacturing instructions. It is not unusual for the design to be transmitted in stages.

Common Design Control Violations

Well-documented control systems and process automation facilitate the good design and engineering practices. This allows for the production of high-quality products. This is crucial when you are navigating the regulatory compliance pathway. Design issues can overlap with other areas. These are some of the violations that were observed during design inspections to help you avoid any potential problems in product development:

• There are insufficient or inadequate procedures for design changes.
• The design validation risk analysis was not done or is insufficient.
• Avoid using a risk-based approach to design reviews.
• Inadequate documentation or procedures to prove that design outputs meet design inputs.

A product design strategy compliant with regulatory guidelines can bring many advantages and competitive advantages. For example, a quality product ensures a faster submission time and reduces the risk of rejection. In addition, it increases your chances of compliance and a successful product launch.
