Innovating Health: Medical Device Development

To give you an idea of how important medical devices have become in healthcare, the global market was valued at approximately $456 billion in 2021. It is expected to grow at an annual growth rate of 5.4%, which means it will likely reach nearly $603 billion by 2027. (1) So, you might be asking, what does this mean if you want to develop your medical device?

First, you need to consider the driving factors for this growth. The most important ones include the advances in medical technology, an ageing population, and rising chronic disease prevalence. All these factors drive the need for innovative healthcare solutions. The next step is to understand that medical devices are healthcare tools with various useful features.

To develop a medical device, you must conduct thorough research and undergo extensive design, development, documentation, and regulation processes. In this article, we have detailed the procedures involved at every stage of development. It is crucial to adhere to each phase while fully complying with regulatory standards.

What are medical devices, and what is their purpose?

Medical devices are tools defined by the World Health Organization (WHO) for specific medical uses like diagnosis, treatment, or disease prevention. To be more specific, the European Medical Device Regulation (MDR 2017/745) defines a “medical device” as any tool, software, implant, or other item designed by its manufacturer to be used for medical purposes. This can include devices that monitor health conditions, predict medical outcomes, or provide information about tissues and bodily fluids. (2)

Unlike drugs, medical devices do not primarily work through biochemical action in the body and might be supported by drugs in their function. Medical devices range from simple items like thermometers to complex machines like MRI scanners. These scanners create detailed body organ images using magnetic fields and radio waves.

Furthermore, medical device product development of artificial hearts and health apps is essential for improving patient care. That is because artificial hearts are vital for patients waiting for heart transplants. Similarly, mobile apps for diabetes help users track blood sugar levels and manage their medication. (3)

Another example is the medical device software for diabetes management, which can track blood sugar levels, dietary habits, and medication adherence. Why does that matter? As a medical device engineer, you can significantly improve patient self-management by developing such wearable medical devices. This would make the job of medical professionals easier, as it would encourage patients to seek help sooner with the information provided by their wearables. (4)

If you are a medical software manufacturer, one of the most important questions is: Should my medical software adhere to the medical device regulations? According to the FDA, software as a medical device (SaMD) is software intended to be used for one or more medical purposes without being part of a hardware medical device. (5) Similarly, European legislators guide the qualification and classification of software as a medical device. (6)  

What are the 6 stages of medical device development?

Medical device product development is a complex process. It is designed to ensure that new products are safe and effective before they reach the consumer market.

This process can be broadly divided into six key stages:

• Concept and feasibility. In this early stage, as a developer, you can explore the viability of an idea. The best way to start the medical device product development process is to assess the device’s need, market potential, and technical feasibility. During this step, you can create an early prototype and perform initial market research to help evaluate demand and competition. (7) 
• Design and development. Here, you need to figure out and outline your device’s technical details. Prototypes are made and tested repeatedly to refine the design and fix any issues. This phase will determine if your device meets all functional requirements. 
• Preclinical testing. Before human testing, the device you are developing undergoes strict lab tests for safety and effectiveness. The standard medical device manufacturing process includes in vitro (test tube) and in vivo (animal) studies to check the device’s impact and identify risks. (8) 
• Clinical trials. One important aspect of this step that you need to be prepared for is that your device is going to be tested on humans to assess its performance and safety. This stage is going to gather data on the function of your device in real conditions. It includes multiple testing phases for both short and long-term use. (9) 
• Regulatory review. Once you have passed the successful clinical trials, your device will face a regulatory review. Agencies like the U.S. Food and Drug Administration (FDA) or the European Medicines Agency (EMA) analyze the research and test data to confirm that your device is safe and effective. Approval from these agencies is needed before you can begin outlining your medical device marketing strategy. (10) 
• Manufacturing and post-market surveillance. If your device has reached this step, congratulations, as it has been officially approved. Now, the actual medical device product development begins by focusing on scaling up manufacturing while ensuring quality. After it is released into the market, ongoing surveillance tracks your device’s performance and detects any unexpected issues. (11) 

Following these six key steps of medical device product development will greatly increase the success of your device. This is the best way to ensure that your device adheres to the highest standards of safety and efficacy to get approved for use. 

Why is medical product device design important?

Medical device design is one of the most important steps that you can take as a developer. In order to ensure the device’s functionality, you need to improve the user experience significantly. This is important, as it affects patient safety and the probability of success of treatments.

Feel free to use ergonomics to make your devices more user-friendly and safer. By improving the aesthetics of the software, on the other hand, you can enhance patient engagement. You still need to meet regulatory standards during your medical device product development, as it is essential for the safety and effectiveness of your device. (12)

For instance, one of the best medical alert devices is the portable ultrasound machine. They are a success in design, combining portability with ease of use. They enable quick diagnostics from rural clinics to emergency scenes. This shows how strategic design is key to improving healthcare delivery and patient outcomes.

Especially under regulations like EMDR 2017/745, medical device design holds critical significance due to its direct impact on the quality and safety of healthcare delivery. Developers must ensure that designs are functional, safe, and compliant with these regulations. (13)

Important regulations developers should consider in the EU and the US

In the EU, the Medical Devices Regulation (MDR) requires thorough clinical evaluations, risk assessments, and CE marking to ensure safety standards are met. In the US, under FDA oversight, high-risk devices need premarket approval, while similar existing devices can use the 510(k)-clearance pathway. The US also enforces manufacturing standards through the Quality System Regulation (QSR). (13)

The EU’s MDR generally demands more documentation, which makes the whole medical device product development process more complex. The US system, however, may allow quicker market access for some devices through the 510(k) process. For example, a cardiac monitor faced strict MDR requirements in the EU but received quicker 510(k) clearance in the US. This case helps you better notice the differences and common safety goals of both regulatory systems.
