    How to choose a 510(k) predicate — and defend it

    The predicate is not a formality. It is the question your entire file answers — so choose it the way the reviewer will read it, record by record.

    Traditional, Special, or Abbreviated — choosing your 510(k)

    Three doors into the same finding of substantial equivalence. The right one depends on what changed — and who holds the device it changed from.

    Building the 510(k) — eSTAR, screening, and the testing burden

    The file is a testing programme wrapped in a template. The template is mandatory now — and it will not let you leave the hard parts blank.

    The 510(k) review — from submission to the SE letter

    FDA guidance vs. regulation — what actually binds you

    Most of what FDA publishes is not law, and says so on the first page. Knowing what binds you — and what is the reviewer's yardstick — changes how you argue.

    What a PMA actually is — when FDA approves a device

    The one device pathway where “FDA-approved” is the right phrase — because for a Class III device there is no predicate to stand behind. Your evidence carries the whole file.

    What an NDA actually is — and the PDUFA clock

    What a 510(k) actually is — and what clearance means
