FDA publishes guidance on device changes:

The US FDA has published a draft guidance document entitled "Deciding when to submit a 510(k) for a change to an existing device". The document includes a flowchart model which can be used by manufacturers to help decide whether modifications to a device necessitate a new 510(k) submission (see Clinica No 671, p 5).
