394 medical device reports received by FDA name the brand "Harmonic Ace 5mm Shear" (instrument ultrasonic surgical); the manufacturer given most often on reports is Ethicon Endo-Surgery; received from March 2018 to December 2025. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.

8 reports arrived in the 12 months to August 2026, down 92% from 100 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 injury (88.6%), malfunction (6.9%) and death (4.6%); across all instrument, ultrasonic surgical reports (product code LFL) death is recorded in 0.1% and malfunction in 94.9%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are patient device interaction problem (62.7%), detachment of device or device component (2.8%) and insufficient device problem information (2%). The patient problems coded most often are hemorrhage/blood loss/bleeding, blood loss and fistula. 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."
