Skin irritation occurs when a substance causes inflammation or damage to the skin upon contact. For medical devices, this can be a serious concern, as they are often in prolonged contact with the skin. The consequences of not adequately testing for irritation can range from minor redness to severe dermatitis, leading to discomfort, injury, or even infection in users. Therefore, reliable testing methods are crucial to ensure that products are safe before they reach the market.

ISO 13485:2016 is the international standout standard that defines the precise requirements for a Quality Management System (QMS) specific to the medical device industry. Unlike general business quality frameworks, it prioritizes patient safety, clinical efficacy, and global regulatory compliance ahead of standard consumer satisfaction metrics.

Whether you are an active medical device manufacturer, a software-as-a-service (SaMD) developer, an importer, or an EU/UK distributor, demonstrating compliance with this standard is virtually mandatory to secure and retain critical market access.

How to Structure a Medical Device Technical File

Blog, EU Regulations, Guides and Advice, Medical Device Pre-launch, UK Regulations /

A medical device technical file is a concise set of documents created by a manufacturer to explain the performance and safety of a particular Medical Device in a clear, well-organized, easily searchable, and unambiguous manner.

In order to prove compliance with the general safety and performance criteria of the legislation, the manufacturer must have – and keep up-to-date – this technical documentation, regardless of  medical device class.

Medical Device Regulatory Strategy for Startups: A Complete Guide (2026)

Blog, EU Regulations, Guides and Advice, Medical Device Post-launch, Medical Device Pre-launch, UK Regulations, USA Regulations /

Launching a medical device startup can be an exciting journey, but regulatory requirements are often underestimated during the early stages of product development. Many start-ups focus on innovation, funding, and product design while leaving regulatory planning until later. Unfortunately, this approach can lead to significant delays, increased costs, and even project failure.

A well-defined regulatory strategy should be established as early as possible to ensure your medical device reaches the market efficiently while meeting all applicable regulatory requirements.

In this guide, we explain how medical device startups can build a successful regulatory strategy and avoid common compliance pitfalls.

Medical Devices Classification UK

Blog, UK Regulations /

In the UK Medical Devices are categorised into 7 classes, these are Class I, Class Is (sterile), Class Im (measuring), Class Ir (reusable surgical tools), Class IIa, Class IIb and Class III.  

Class I devices are considered to be of low risk, Class II devices as medium risk and Class III devices as high risk. 

Depending on the classification of device determines the regulatory conformity pathway that needs to be taken to gain compliance and allow manufacturers to place product on the UK market.
