Sometimes changes in process can have a dramatic effect on product registration. There are several events that can cause a re-registration of a registered medical device. A new product name, part number, material, manufacturing site, country of origin, business name or manufacturing process are common re-registration triggers. It all depends on the specific regulations of the country involved.
We in the medical device industry throw the term CAPA around like it's a word that is common-place in our society (though, here in Pittsburgh, you'll get a lot of confused looks if you tell someone you've opened a CAPA as it is a local performing arts school. That's a strange nightmare with future Broadway stars re-enacting a root cause analysis!).
