Medical Device & Product Design Services

Designing medical and laboratory products carries a different set of demands to most product design work: strict regulations, real user safety, and commercial pressure, all at once. Our medical device design services are built around juggling those three things together from the start, with regulation shaping the design from day one.

Let's get talking

Making medical device design work for your business

We've been helping medical and scientific companies turn ideas into successful products for over two decades. That means more than good design, it means understanding the parts of medical device development that make this sector genuinely different from others, and navigating them alongside you.

How 4D approaches medical device design

Three things shape how we handle a medical device project.

Regulations built in from day one

Medical regulation isn't something we treat as a barrier to work around after the fact. We build regulatory considerations into our thinking from the start, which means fewer costly changes later and a smoother path to market than bolting compliance on at the end.

Costs kept in check without cutting corners

Medical device development is a serious investment, so we're always thinking about your budget alongside the design itself, from material choice to designing for efficient manufacturing. The goal is a device that performs properly and still makes commercial sense.

Built to work for everyone who'll actually use it

A device needs to work in the real world and in the lab. We think about everyone who'll use your product, from healthcare professionals to lab technicians, grounded in our user-centred approach to make sure it works for all of them.


Medical device design in practice

Two products where regulation, safety and commercial success were designed together.

Micrima: For Micrima's breast-scanning device, we designed an internal Faraday shield and outer docking station to house a sensitive electronics assembly, working to EN 60601 so the device could progress to clinical trials. Compliant working prototypes were ready within 12 weeks of briefing, and the samples went into trials in NHS hospitals. Chief Technical Officer Leigh Cornock credited the speed and the compliant enclosure with getting their technology out for trials.
Medisyne: Medisyne's INFLUx is an automated urine monitoring device built for hospitals during the COVID-19 pandemic, taken from concept to deployment in weeks. Real-time feedback from healthcare professionals shaped the design throughout, with intuitive usability, robust construction and easy cleaning treated as essential requirements for busy hospital environments from the start of the brief.
ISO 9001:2015 Certified
This certification proves we have a robust design process in place, crucial to ensure the right documentation is maintained from the start. We often work within our clients' ISO 13485 systems for medical product development, allowing us to work as a seamless extension of the team and expediting the regulatory approval process.
Experts in medical device design, working with fast moving start-ups and global brands.

Decades of commercially minded design experience

We combine experienced creative talent with a practical understanding of marketing, end-user understanding and a thorough knowledge of mechanical engineering, so we can deliver fresh, innovative design solutions built around your product.

Making medical device development work harder for your business

Getting a medical device right means more than good design, it means real commercial advantage at every stage.

Making sure your investment makes sense

Every material and manufacturing decision gets weighed through a commercial lens. We've helped clients reduce production costs by up to 30% while improving device performance.

Handling the regulatory maze without slowing everything down

We build ISO 13485, MDR and UKCA considerations into the design process from day one, meaning fewer expensive changes later and a clearer path to market. We've helped clients navigate complex Class III device requirements while speeding up their development timeline.

Protecting your investment long-term

Getting to market isn't the finish line. We help you future-proof a device, designing for easy updates, manufacturing scalability, or platforms supporting multiple product variants.

Thinking beyond just getting to market

We help you plan for scaling production, new markets, or the next generation. One client's device used modular components that made regional adaptations 40% faster.

Turning the highly technical into business advantages

We look at how a device fits into real workflows, alongside its features. One diagnostic device redesign improved accuracy and cut lab technician training time by 50%.

Bringing everyone together

Medical device projects involve clinicians, engineers, manufacturers and regulatory experts, and getting them aligned is core to how we work. We've helped clients reduce development cycles by months simply by getting this collaboration right from the start.

Medical device design FAQs

Do you understand medical terminology and standards?

Yes, we know our way around ISO 13485, MDR, UKCA and the wider medical terminology, but we won't blind you with jargon. We'll talk to you in plain English about what actually matters for getting your product to market.

Are you designers first, or do you think commercially too?

Both, and they're not separate considerations. Every decision, from materials to manufacturing methods, is weighed against giving your product the best chance of commercial success in the real market it's launching into.

What happens after we get regulatory approval?

Approval isn't the finish line, it's the start of the next phase. We help you think about what comes next, whether that's scaling production, entering new markets, or planning your next product iteration.

What kinds of medical and scientific products have you worked on?

A wide range, including diagnostic devices that needed to hit specific price points, laboratory equipment built to work in demanding environments, and medical devices that had to meet strict regulatory requirements, all while keeping an eye on business success throughout.

How do you handle the regulatory maze without slowing everything down?

By treating regulation as something to plan around from day one. Solid experience with ISO 13485, MDR and UKCA means fewer expensive changes later and a clearer, faster path to market.

How do you protect our investment for the long term?

By building in future-proofing wherever it makes sense, designing for easy updates, planning for manufacturing scalability, or creating platforms that support multiple product variants, so decisions made now continue to pay off well after launch.

How do you turn technical requirements into business advantages?

By looking at the whole picture: how a device will be used, maintained, and fit into existing workflows, alongside its technical features. That practical view is what turns a device into something that wins contracts and grows market share.

How do you manage projects with lots of different stakeholders?

By getting everyone – clinicians, engineers, manufacturers, regulatory experts, and so on – pulling in the same direction. This helps translate technical requirements into practical solutions that work for the whole group, which is a core part of how we run a project.
