Working with Remedee Labs, which has patented technology for non-pharmaceutical treatment of chronic pain, we reviewed and critiqued their existing design, with a particular focus on the antenna that is critical for power transfer into the skin.

What we do best

Safety-Critical Design and Regulatory Compliance

For medical device development specifically, our engineers work to the same rigorous standards applied in aerospace and defence, carrying that culture of zero-failure design into the healthtech sector. Failures can have life-or-death consequences, so systems must be highly reliable, fault-tolerant, and designed with redundancy, and these requirements are often reflected in stringent verification and validation protocols

Our Quality System is compliant to ISO 13485, and where appropriate our projects will comply with, amongst others, ISO 14971 for risk management, IEC 60601 for electronics, and IEC 62304 for medical software.

Regulatory compliance also extends to cybersecurity, and for connected devices HIPAA and GDPR compliance is critical.


Complex Integration

Complex Integration

The electronics and software that Plextek develop will often form a vital part of complex medical systems, and as such integration within the wider system architecture is an essential part of our offering to clients.

Software development is often complicated by the requirement for complex signal processing, stringent data integrity, along with real-time operation.


Reliability Under Constraints

Plextek prides itself on the development of low size, weight, and power devices in all the markets in which it operates. These constraints are even more prevalent in the medical sector. The electronics within medical devices also often have to contend with additional constraints such as sterilisation, long-term use, and harsh medical environments.


Long Product Lifecycles

Whilst medical systems can take many years to launch, they also tend to remain in use for decades. Therefore, designs must play close attention to maintenance, updates, and component obsolescence management.

Why choose Plextek for your project?

We Deliver

We’ve built our reputation on delivering systems that work when lives depend on them. Our ISO 13485 certification reflects the rigorous quality processes we’ve refined across aerospace, defence, and medical projects.

We can handle everything from the first circuit sketch, whether that’s medical device design and custom technology development, writing software, or navigating compliance. This means fewer handoffs and better integration. We work closely with clients throughout the process, adapting to how you prefer to operate, and we stick around after launch.

Standards & Certifications
  • Plextek holds ISO 13485 certification for Medical Device Quality Management Systems.

We design and develop to the highest industry standards including ISO 14971 for risk management, and IEC 60601 for electronics. Our medical device software development follows IEC 62304, and IEC 62366 for usability engineering. Our connected devices comply with HIPAA and GDPR requirements for data protection and privacy.
