We submitted our technical documentation for assessment to the MDR back in August and are still awaiting the review. We've been told by our NB that we can't make changes to the TD in the meantime. However, TD is a live thing and regular updates are necessary and we have several updates to make (updated VMP, CER etc). I've ended up with with two parallel TD files, one frozen since August and a live one I am updating. I wondered how others have handled this?
