    Hi All, 

    Can someone point me to the FDA regulations related to device life / expected useful life? 

    Kind regards,

    Any particular regulations?  There's a definition at 21 CFR 803.3 (f).​

    There are some explanations of device life in different FDA guidance documents, couple places in the regulations, but as far as I know there is not a succinct definition for device life.  Personally, I can see this is not defined because device life can vary quite a lot depending on device type.  And in fact there are terms such as device life, usable life, serviceable life, shelf life, expiration date; these all need to be defined by the company.  Depending on your device type the device life should be clearly described including justification for device life, according to different parameters such a usable life an/dor shelf life.

    There is a defined term in IEC 60601-1, ed. 3.1 which is in clause 3.28 for EXPECTED SERVICE LIFE which is "time period specified by the MANUFACTURER during which the ME EQUIPMENT or ME SYSTEM is expected to remain safe for use (i.e. maintain BASIC SAFETY and ESSENTIAL PERFORMANCE)."

    [See my previous reply]

    So, if your device is an electro-medical device that meets the scope, clause 1, of IEC 60601-1, ed. 3.1 than you can use this definition I mentioned just previously for EXPECTED SERVICE LIFE of clause 3.28.  In clause 1 you do need to make sure you also meet either the definition of MEDICAL ELECTRICAL EQUIPMENT of clause 3.63 or MEDICAL ELECTRICAL SYSTEM of clause 3.64 to fall under the scope of the standard.

    Depending on the type of device, Cybersecurity needs to also be factored into this discussion.  With more and more devices being build with software, whether it's commercial off the shelf or open source, there needs to be consideration for how to manage devices when the software that is part of the device "expires".  For example, there are still devices in use that run the Windows XP operating system, which Microsoft ended support for in 2014.  This means security patches are no longer provided for the operating system, so if a new vulnerability comes up that could present a patient safety risk, it cannot be fixed through a security patch and based on the 2016 Post Market Cybersecurity Guidance from FDA it could be considered a recall

     

    The term "end of support" is defined in the FDA's 2018 draft guidance, "Content of Premarket Submissions for Management of Cybersecurity in Medical devices", with the expectation that support and lifetime planning is done for Cybersecurity and shared with customers. 

     

    Just another element to consider if building and managing devices with software.
