Once the 4th Edition is published, redesigns and QMS updates will be far more costly.

Direct insights from someone in the development of IEC 60601-1, 4th Edition

Get an insider’s view of the upcoming changes, their real-world impact, and how to prepare, from someone directly involved in developing the standard.

Event Recap – MLVx Friday In-Focus

On Friday, August 15, the MLVx Friday In-Focus with Sean Smith brought together Leonard (Leo) Eisner, The IEC 60601 Guy, and 110+ professionals from around the globe, including the UK, Romania, US, France, Switzerland, Germany, Finland, and Pakistan, representing medtech manufacturers, regulators, test houses, and standards developers.

We focused on the impact of IEC 60601-1, 4th Edition, the global standard that defines safety and essential performance for medical electrical equipment, and what’s coming that many companies are still not prepared for.

The highlight was an impromptu expert panel with leaders in risk management, software, cybersecurity, regulatory submissions, and combination devices. Together, we tackled questions from every angle, sharing real-world insights on design, testing, and compliance challenges. The discussion showed exactly what’s possible when top experts collaborate to help the industry prepare for disruptive change.

If you missed the live session, this recap and presentation will help you understand what’s coming — and more importantly, how to prepare.

Join me, Leo Eisner, The IEC 60601 Guy, as I lead an interactive and fun workshop at the 10X Medical Device Conference in Newport Beach, Ca on May 7 – 8, 2025. Turn Medical Device Standards into Your Competitive Advantage, and discover practical strategies to leverage standards, avoid costly errors, and accelerate your product development cycle.

Don’t make the 5 costly mistakes companies make with Medical Device Standards. Learn from the IEC 60601 Guy himself.:

• Late Identification of Applicable Standards: Leads to expensive redesigns and delayed timelines
• Ignoring Expert Standards Guidance: Results in regulatory rejections and costly resubmissions
• Unprepared Risk Management File for Testing: Risks unnecessary costs due to lack of strategic planning for compliance.
• Unprepared Regulatory Submissions: Leads to costly setbacks and market-entry delays
• Underestimating Education and Training: Creates knowledge gaps, increasing errors and compliance risks.

I want to thank Sean Smith and his team from 10X for all his help and dedication for putting on this event. He is doing an amazing job and please contact him if you are interested.

 My conversation with Subhi Saadeh of Combinate Podcast was very intriguing and he does a fun podcast. Check out the podcast as I talk about Standards.

We covered a lot of ground in a short time (it flew by for me – I’m sure it will for you too) and if you compare him to an architect he would build something similar to the Louvre Museum with its very unique but beautiful peaks and valleys with surprises around every corner. The Lourve is recent in my mind as I was at an ISO TC 210 standards meeting in Paris Dec ’23 and visited the Louvre. One of my many travels around the world in support of standards development over the last 20 years.

He really does his research. He found my old reconnaissance standards database I was planning to publish but never did. That was a total surprise.

We dive right into standards in many ways that you may not have thought of before in Podcast :
☞ The explosion of standards vs no standards (or chaos of no standards)
☞ The impact of standards on medical device development
☞ Standards and Regulatory Challenges
☞ My Notified Body Auditing Experience, Authorization Process, Product Reviewer
☞ The Challenges of Maintaining and Updating Standards

2 February 2022 

On 1 February 2022  the Gov.UK website updated their Guidance on Using the UKNI Marking. It was originally published on 31 December 2020. This is guidance for placing goods on the Northern Ireland market.

The UKNI mark applies for Northern Ireland specifically.

Contents of the current UKNI Guidance is

1. Overview
2. Check whether you need to use the UKNI marking
3. When to use the UKNI marking
4. How to use the UKNI marking
5. Technical documentation
6. Webinars
7. More information

The Guidance document also points users of the Guidance to the other Marking of concern. It states “For similar obligations that apply when using other conformity markings, see how to use the UKCA marking.” This is for placing goods on the British (UK) market.

Another link in the Guidance that is critical if you need to place a medical product on the UK market is looking at the UK Market Conformity Assessment Bodies (UKMCAB) database. This db you want to make sure you find a Medical Device Assessment Body that covers your device. At first glance there now are a lot of bodies (157 currently) in the db but not all of them fall under medical devices. There are still only 3 of them and they are the usual suspects being BSI, UL and SGS. Best way to search is under the “Medical Device” under the Legislative Search details option.

Regulatory Update – January 2022 Index

I have 4 Regulatory updates (US (2), England, Scotland & Wales (1), EU 1)) for you that are full of great information. Below is a mini index so you can jump around the world as needed – Enjoy and let me hear your feedback on Linked for this post.

1. FDA Updates Recognized Consensus Standards db with List 057
2. FDA Guidance documents Issued – Final and Drafts Recently
3. EC Has Finally Set-Up a Harmonised Standards Website for MDR & IVDR
4. UK Designated Standards for Medical Devices, Active Implants, and IVDs published

FDA Updates Recognized Consensus Standards db with List 057

Read the Federal Register Notice for the modification of list 056 on 9 Dec 2021 to see specifically which standards were withdrawn (you can’t see that detail on the db as withdrawn standards are not shown on the db). The ones that are transitioned and the transition periods are noted but only for the transition period so it is always good to review the Federal Register Notices to understand the full picture in my humble opinion.

Download the table with the list 057 Recognized Consensus Standards for the full list of standards that were updated on this latest update.

Or you can go to the FDA’s Recognized Standards db and search for 12/20/2021 to 12/20/2021 Publication date range to see the 90 standards that are part of the List 057 updates (some are just version changes, some are new standards – See the Federal Register Notice above)

FDA Guidance documents Issued – Final and Drafts Recently

FDA has been busy with Draft & Final Guidance documents in the last 90 days. I put together a document of some of the more relevant Guidance documents for the medical device industry over the last 90 days. This download includes a Comment column that is a summary of the Guidance (FDA & sometimes my comments added). If the Guidance is a draft I provide the comment link if you would like to send in a comment to the FDA (public or anonymous can be posted), of course the link for the guidance, and more. The Guidances are: 1) Combination Devices (Final), 2) Patient-Reported Outcome Instruments for Use in Medical Device Evaluation, 3) Patient Engagement in the Design and Conduct of Medical Device Clinical Studies, 4) Assessing the Credibility of Computational Modeling and Simulation in Medical Device Submissions, 5) Technical Considerations for Medical Devices with Physiologic Closed-Loop Control Technology, 6) Referencing the Definition of “Device” in the Federal FD&CA in Guidance… 7) Content of Premarket Submissions for Device Software Functions.

EC Has Finally Set-Up a Harmonised Standards Website for MDR & IVDR

The European Commission overhauled the sectoral website on Medical Devices in now accessible from the DG SANTE’s Public Health website – a new specific webpage on Harmonized Standards has been set up from the web page “Medical Devices – Topics of Interest”, which has some great topics of interest including Notified Bodies (You can find the NBs for both the MDR & IVDR, the codes they are designated under & more info), UDI (Bountiful resource page), Reprocessing (Well worth reading to understand where the European Commission and each country stands on this issue currently), Latest Updates (separate web page), and more. The Harmonisation web page contains the links to the standardization requests in force and to the publications in the OJEU of references of harmonized standards conferring a presumption of conformity in support of the MDR & the IVDR. The page will gradually grow with more publications, and also with future amendments to the standardization request.

For the latest lists of the MDR & IVDR Harmonized Standards please go to my previous post. Most likely the next update likely to occur March /April 2022.

The above information is thx to Mario Garbielli Cossellu a Policy & Legal Officer at the European Commission provides many great updates on the MDR & IVDR. Check out his recent posts there is always some great content to keep up to date on. I’ve been following him for years on LinkedIn.
