If you have a sterile implantable medical device that is sterilized by Ethylene Oxide (EO aka ETO) and want to extend the shelf life, how many product batches or lots would need to be verified via testing in order to justify the extension? Is there a general best practice? If so, which standard or regulation or guidance would direct us to verify such a number of lots to test (for example 1 lot or 3 lots etc.)?
