@all thanks for your inputs.
Since 2024, a medical device has undergone changes such as design updates and additional testing. As a result, more information is now being captured in the Device History Record (DHR).
One of these design changes was significant enough to trigger a new 510(k) submission. This updated 510(k) reflects the new design and would ultimately supersede the previous cleared version once approved.
However, there is existing inventory that was manufactured in 2024 and is currently sitting in the warehouse. These devices were built to the previously cleared design, not the updated one described in the new 510(k).
My questions are:
- Does the existence of an updated 510(k) submission mean that the previously manufactured devices are now noncompliant, even though they were built and documented under the earlier cleared version?
- While the updated 510(k) is under FDA review and not yet approved, is it still permissible to market and sell devices that fully comply with the currently cleared 510(k)?
- How should this situation be viewed from a compliance and inspection standpoint, especially regarding DHR alignment and inventory manufactured prior to the design change?
Any insight or references would be appreciated. Thanks!
Depends on why the change was made. Was it for safety reasons, to correct known issues? Is the previous clearance within the boundaries of the new clearance? Did you make the change to maintain product conformance to what you previously submitted, or are you adding something new?
Do you have traceability to differentiate between the different versions? Part number, version, etc. Traceability is my biggest concern here because you need to be able to show that you 1) didn't start selling the new device until you got clearance and 2) can maintain traceability in the case of a recall or field correction.
The existence of a new
510k doesn't mean anything, on its own. A 510k is
not a QMS document and it generally doesn't contain/dictate much about how a device is actually manufactured - there's nothing magical about a clearance letter that suddenly makes your product unsellable. You need to assess the
change to the device and disposition it accordingly. This is more of a design transfer question than a clearance question.
Some examples off the top of my head where I would be fine with selling existing stock:
- Packaging material change due to discontinuation of the existing material
- Sterilization change to a different method (eg, change from gamma to EBEAM)
- Change to add a new indication to the labeling
- Material change that isn't intended to impact performance of the device but still triggers a submission for biocompatibility or something like that.
- Shelf life duration increase (definitely traceability concerns here just for inventory management)
- Change from MR unsafe to MR safe/MR conditional
- A dimensional change or addition of a new feature, IF you change the part number and call it a Version 2.0
Some examples that might NOT be ok to sell (things in this category may even require an HHE and/or recall):
- Material change due to urgent issues in the field (metal on metal hip implants, Chinese titanium,)
- Adding a contraindication or warnings/precautions
- Addition of a new safety feature (eg, adding an alarm of some sort to an active device)
- Change to comply with a new standard or regulation that could impact product performance (e.g., if you never complied with ISO 80369 for luers, and you're finally updating the design to comply)
You should have some sort of disposition question as part of any design transfer - what would you do with ANY change, regardless of whether it had a submission or not? The only thing that a 510k changes about the situation is it basically guarantees that you'll get audited on it for your next MDSAP audit.
