Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.
33 reports arrived in the 12 months to August 2026, down 40% from 55 in the 12 months before.

The patient problems coded most often are hemorrhage/blood loss/bleeding, tissue damage and no patient involvement. 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."
