CE Marking Medical Devices

Blog, EU Regulations, Guides and Advice, Standards, UK Regulations / David Small

The CE marking of medical devices and in vitro diagnostic devices (IVDs) is a requirement of EU regulations (EU 2017/745 for medical devices and EU 2017/746 for IVDs) to lawfully place medical devices on the EU market. Manufacturers must affix the CE mark on the medical device or IVD itself and on the primary packaging (or just on the packaging if affixing to the device itself it not possible). The CE mark should also be placed on any instructions for use and any labelling. The use of the CE mark identifies that a medical device or IVD conforms to EU regulatory requirements and is a symbol that a device meets safety standards.

Skin Irritation Testing in the biological evaluation of medical devices (ISO 10993-23)

In Vitro Skin Irritation Testing: ISO 10993-23 Standard

Blog, EU Regulations, Guides and Advice, Medical Device Pre-launch, Medical Device Validation, Standards, UK Regulations, USA Regulations / David Small

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.

Ensuring medical device users can operate medical devices safely and easily is of vital importance to reduce user errors IEC 62366 provides a framework for medical device manufacturers to develop safe medical devices with the user in mind.

IEC 62366-1 Usability Engineering for Medical Devices: Ultimate Compliance Guide

Blog, Guides and Advice, Medical Device Pre-launch, Medical Device Validation, Standards / David Small

In medical device design, technical efficacy is only half the battle. A device can be engineering perfection, but if a clinician or patient misinterprets a screen prompt or a physical control, the result can be catastrophic use error.

This is where IEC 62366-1 comes into play. It is not an optional layout framework; it is a globally harmonized international standard that mandates a structured Usability Engineering Process (also known as Human Factors Engineering) throughout the entire product development lifecycle. If you are pursuing an EU MDR CE mark, UKCA marking, or an FDA 510(k) clearance, establishing explicit compliance with IEC 62366-1 is a fundamental requirement for market access.

MDR Article 120

Blog, EU Regulations, Guides and Advice, Patient Guard News, Standards / David Small

In the fast-paced world of medical device manufacturing, regulatory standards are the bedrock of patient safety and product quality. Recently, the European Union has taken a significant step by extending Article 120 of the EU Regulation 2017/745 and EU Regulation 2017/746. This move has been made to address the mounting backlog of CE mark certifications and re-certifications within notified bodies, the entities responsible for ensuring that medical devices meet stringent quality and safety requirements before they reach the market. In this blog post, we’ll delve into the implications of this extension for medical device manufacturers and emphasize the critical importance of continued compliance.
