Summary

The FDA's MAUDE database contains 82 adverse event reports that list this exact device (DI 04035479100391), received between Mar 18, 2019 and Jul 2, 2026 — classified as 1 death, 22 injuries, 59 malfunctions.

The most frequently reported specific device problem is “Over-Sensing” (24 reports).

Reports come from manufacturers, hospitals and patients and are not verified by the FDA. A report does not prove the device caused the event, and counts can't be used to compare devices or estimate failure rates. What reports can and can't tell you · How this data works · Data updated Oct 16, 2026.
