0 reports arrived in the 12 months to August 2026, and none in the 12 months before. FDA releases MAUDE data monthly; reports can arrive months after an event, so the newest months grow in later releases. The event types recorded are injury (82.7%), malfunction (16.3%) and death (1%); across all pulse generator, permanent, implantable reports (product code NVZ) death is recorded in 4.1% and malfunction in 43.5%. Event type is the reporter's classification of the report, not a verified outcome.
The device problems coded most often are premature discharge of battery (73.8%), nonstandard device (44.5%) and battery problem: high impedance (19.3%). The patient problems coded most often are dyspnea, complaint, ill-defined and death. FDA states that "MDR data alone cannot be used to establish rates of events, evaluate a change in event rates over time or compare event rates between devices. The number of reports cannot be interpreted or used in isolation to reach conclusions about the existence, severity, or frequency of problems associated with devices." It adds that the reporting system "has limitations, including the potential submission of incomplete, inaccurate, untimely, unverified, or biased data."
