FDA's MAUDE database holds 1,349 reports that name the brand "PENTAX Medical" (imagina colonoscope us only), received between August 2024 and August 2026; the manufacturer given most often on reports is Hoya Pentax Tokyo Office. Spellings of one product vary from report to report.

807 reports arrived in the 12 months to August 2026, up 52% from 530 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 (96%), injury (3.7%) and death (0.3%); across all colonoscope and accessories, flexible/rigid reports (product code FDF) death is recorded in 0.1% and malfunction in 98.1%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are fluid/blood leak (25.2%), optical obstruction (24.4%) and no display/image (20.9%). The patient problems coded most often are foreign body in patient, airway obstruction and device embedded in tissue or plaque. 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."

Brand, generic and manufacturer names are as written on the reports; product code names come from FDA's device classification. A report counts here when any device it lists carries this brand name after punctuation and capitalisation are normalised. No report narrative, lot number, patient detail or reporter identity is published. See the methodology and sources; FDA's record is authoritative, and corrections are handled within five working days.
