FDA's MAUDE database holds 1,025 reports that name the brand "Single Use Distal Cover" (distal cover), received between June 2019 and August 2026; the manufacturer given most often on reports is Olympus Medical Systems Hinode Plant. Spellings of one product vary from report to report.

102 reports arrived in the 12 months to August 2026, down 31% from 148 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 malfunction (58%) and injury (42%); across all duodenoscope and accessories, flexible/rigid reports (product code FDT) death is recorded in 0.7% and malfunction in 88.5%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are detachment of device or device component (73.4%), break (8.6%) and device fell (4.4%). The patient problems coded most often are foreign body in patient, laceration(s) and hemorrhage/blood loss/bleeding. 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."
