241 medical device reports received by FDA name the brand "Unknown_Endoscopy_Product" (electrosurgical cutting & coagulation & accessories); the manufacturer given most often on reports is Stryker Endoscopy-San Jose; received from February 2013 to August 2026. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.

22 reports arrived in the 12 months to August 2026, close to the 22 of 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 (69.7%), injury (29.9%) and death (0.4%); across all electrosurgical, cutting & coagulation & accessories reports (product code GEI) death is recorded in 0.4% and malfunction in 80.1%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are output problem (9.5%), poor quality image (8.7%) and break (8.3%). The patient problems coded most often are burn(s), burn, thermal and superficial (first degree) burn. 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."
