Medical Device Development Process – The Full and Only Guide You’ll Ever Need

Medical Device Development Process the guide

There are plenty of medical device types and technologies in the market, but there is one thing in common- All medical devices’ development l begins with an ingenui idea.

The medical device is a large family that includes products designed to diagnose and prevent diseases or other medical conditions used to treat humans or animals.

Medical devices can be an instrument, apparatus, machines, appliances, implants, reagents for in vitro use, medical software, medical mobile/cellular applications, or materials.

The medical device industry is a unique one.

It combined many areas such as mechanics, electronics, biomaterials, software, chemistry and physics, and even biology.

There are also medical device combination products working together with pharmaceutical products. On the other hand, mobile apps and even video games are used to treat patients and different medical conditions.

How does developing a medical device differ from a non-medical product?


Medical device development engineers, who have worked in other industries besides the medical one, know that developing a medical device is more complex and challenging than developing non-medical products.

The medical device is intended to treat sensitive and vulnerable populations (mostly patients) and may affect health conditions and endanger human life. As a result, the Quality By Design approach and extensive documentation level should be implemented in early medical device development.

Knowing the regulatory requirements and establishing the relevant Quality Management System and technical documentation will give the company an advantage in later stages.

Medical device development challenges


The final goal of every medical device development process is to receive the official marketing authorization in global markets such as Eu. and the US following the CE mark and FDA 510K/PMA approval.

Developing a medical device and regulatory marketing authorization is a relatively complicated process. Achieving this critical milestone and avoiding time delays and budget issues along the way is challenging. It is essential “to do it right” in the medical device development and design phase.

This medical device design and development process requires exceptional capabilities. It combines safety, regulatory, quality, and technology challenges and requires a multi-disciplinary set of skills the company should have in this journey.

Medical Device Development Phases

Generally, there are 12 main phases in the medical device development process:
