FDA's MAUDE database holds 179 reports that name the brand "At500" (implantable pulse generator), received between May 2003 and November 2017; the manufacturer given most often on reports is Medtronic. Spellings of one product vary from report to report.
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 (81.6%), malfunction (17.3%) and death (0.6%); across all implantable pacemaker pulse-generator reports (product code DXY) death is recorded in 3.4% and malfunction in 41.2%. Event type is the reporter's classification of the report, not a verified outcome.
The device problems coded most often are failure to interrogate (33.5%), low battery (15.1%) and premature elective replacement indicator (12.3%). The patient problems coded most often are bradycardia, syncope and dizziness. 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."
