Summary

The FDA's MAUDE database contains 90 adverse event reports that list this exact device (DI 00802526531224), received between Oct 12, 2016 and Sep 9, 2026 — classified as 70 injuries, 20 malfunctions.

The most frequently reported specific device problem is “Over-Sensing” (14 reports).

3 other recalls cover devices cleared under the same FDA submission (P910073); they may or may not involve this specific model.

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.
