The 6 Phases of Medical Device Development

News & Insights

Developing a medical device involves several phases that ensure successful and accessible designs, manufacturing, and market entry. Medical devices require adhering to stringent regulations and standards and an error-proof user experience (UX) and user interface (UI) design. These methods encompass a comprehensive approach to medical device development, which consists of six key phases that all developers and stakeholders must adhere to for successful production and distribution.

Phase 0 – Product Definition

Before medical device development begins, the team must comprehensively define the device or system concept. This involves conducting market research, identifying user needs, and establishing key performance indicators and design requirements. Clearly defining the product’s purpose and requirements sets the foundation for efficient subsequent phases of development.

Phase 1 – Ideation and Conceptualization

Innovative ideas are generated and evaluated in a collaborative environment, encouraging the input of every stakeholder and end-user, including patients, doctors, nurses, surgeons, maintenance technicians, and any other individual interacting with the product. Potential concepts are refined and selected for further development through brainstorming sessions, “proof-of-concept” prototypes, and feasibility studies.

Phase 2 – Design Development

The chosen concept is transformed into a detailed design. This involves creating 3D models, engineering the device components, and conducting simulations and prototypes using human factors engineering. Advanced design tools and techniques, such as Design for ‘X’ activities, including but not limited to, Design for Manufacturing (DFM), Assembly (DFA), cost, sterilization, etc.– are leveraged to ensure the complete medical device design’s accuracy, functionality, and manufacturability.

Phase 3 – Refinement and Verification

The design undergoes rigorous testing and optimization. Prototypes are extensively evaluated to validate performance, safety, and usability. Feedback from users and experts is collected and used to refine the medical device’s design and UX. This iterative process ensures that the medical device meets the highest regulatory standards and effectively addresses end-user needs.

Phase 4 – Validation and Manufacturing Transfer

This phase involves validating the device’s performance through clinical trials and obtaining regulatory and FDA approvals. For effective quality assurance (QA) and regulatory adherence, medical devices must submit the inputs and outputs of verification and validation tests to be reviewed by the FDA. Once validated, the manufacturing processes are established to transfer the device design into large-scale production.

Phase 5 – Production

The final phase involves scaling up manufacturing and bringing the medical device to the market. Your design partner will collaborate with manufacturers (Goddard provides both design and low-volume manufacturing options under one roof) to ensure the efficient production of high-quality devices. Strict quality control measures are implemented throughout the process to maintain consistency and reliability. Assessing quality and compliance throughout production should be repeated consistently until the very end so engineers can quickly address any issues that arise before completion.

Common Challenges That Prevent Medical Devices From Getting Onto the Market

Developing and bringing a medical device to market can be challenging. However, working with a knowledgeable development partner can streamline most, if not all, difficulties. Some common obstacles include:

Understanding User Needs

Failure to thoroughly understand user needs can result in a device that doesn’t effectively address the requirements of healthcare professionals and patients. This includes developing a medical device that is error-prone and not user-friendly due to a lack of UI and UX expertise during the design process.

Understaffed Teams

Limited resources and understaffed development teams can lead to delays, inefficiencies, and compromised quality during development. When labor is short, one of the most efficient and effective solutions can be to call in a development firm whose staff and expertise can be invaluable to overcoming your staffing issues.

Lack of Expertise

Lack of expertise in medical device development, regulatory compliance, or specific technological areas can hinder the progress and success of a project. Medical device development is one of the most complex and regulated engineering verticals and can only be successfully executed through expert developers. Bringing in third-party design assistance to avoid these pitfalls is a strong strategy for avoiding development timelines that could fail.

Navigating FDA Regulations

Navigating the intricate landscape of FDA regulations and requirements can be overwhelming without proper expertise and guidance. Therefore, responsible medical device developers must have up-to-date regulatory knowledge and competency throughout the design process. For example, human factors engineering (HFE) is a vital requirement for proper medical device development and an FDA standard. Understanding how to execute HFE into medical device designs properly will ensure this doesn’t need to be implemented after the product is initially developed but throughout the entire process. Working with a development partner well-versed in these design facets is vital to proper and successful medical device development, especially if in-house knowledge or labor is limited.

Medical Device Usability

Designing a device that is intuitive, user-friendly, and addresses the usability needs of healthcare professionals and patients can be a significant challenge. Complex medical devices, such as those involving software or cutting-edge technologies, can pose additional design, development, and regulatory challenges, such as increasing needs for accessibility and flawless UX and UI. Medical devices must work as intended for their end users; anything less would be unacceptable and irresponsible to produce and distribute.
