RebarTMRecalls & reported problems across all models

We found 4 models of RebarTM by Micro Therapeutics, Inc. in the FDA's device registry (GUDID). Together they are named in 126 adverse event reports in the FDA's MAUDE database, received between Dec 4, 2018 and Feb 3, 2026 — classified as 2 deaths, 6 injuries, 118 malfunctions.

The most frequently reported specific device problem is “Physical Resistance/Sticking” (97 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. Widely used products collect more reports, so totals can't be used to compare products or estimate failure rates. Only reports that name a model's exact device identifier are counted.
