323 medical device reports received by FDA name the brand "8mm Mcs Tip Cover Accessory" (electrosurgical instrument accessory); the manufacturer given most often on reports is Intuitive Surgical; received from September 2007 to July 2014. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.

0 reports arrived in the 12 months to August 2026, and none 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 (73.7%), injury (15.5%) and other (10.2%); across all system, surgical, computer controlled instrument reports (product code NAY) death is recorded in 0.6% and malfunction in 90.7%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are arcing (54.2%), hole in material (26%) and replace (7.1%). The patient problems coded most often are burn, thermal, burn(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."
