Expert guidance on 510(k), De Novo, PMA submissions, and 21 CFR compliance. Written to help medical device companies navigate FDA regulatory pathways with confidence.
**Summary:** Medical device manufacturers must submit a new 510(k) when modifications—firmware updates, material changes, label updates—could significantly affect safety or effectiveness. FDA enforcement includes warning letters, recalls, and product seizures for unauthorized changes.
Manufacturers of 510(k)-cleared medical devices must determine whether modifications require a new submission or can be documented internally—getting this wrong risks regulatory action or unnecessary delays. FDA's 2017 guidance provides a decision framework based on whether changes "could affect" device safety or effectiveness, placing the burden on manufacturers to document their analysis regardless of outcome.
