560 medical device reports received by FDA name the brand "Nim 3 0 Mainframe International" (stimulator nerve); the manufacturer given most often on reports is Medtronic Xomed; received from May 2015 to August 2026. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.

69 reports arrived in the 12 months to August 2026, down 55% from 155 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 (96.1%) and injury (3.9%); across all stimulator, nerve reports (product code ETN) death is recorded in 0.2% and malfunction in 83.4%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are incorrect, inadequate or imprecise result or readings (32.1%), false negative result (12%) and inappropriate audible prompt/feedback (8.2%). The patient problems coded most often are nerve damage, no patient involvement and paralysis. 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."
