Operational response

A Class I device recall indicates a strong likelihood of serious adverse health consequence or death from continued use. Identify affected units by serial number, lot, or GTIN against your inventory and against implanted-device patient registry. Pull affected inventory from active use immediately. For implanted devices, follow the recalling firm’s patient-notification protocol; in most cases this requires informing affected patients and their treating physicians directly.

For the official FDA enforcement record, see FDA's Recall Search.
