1,155 medical device reports received by FDA name the brand "BIM400 Implant Magnet" (cochlear baha attract system); the manufacturer given most often on reports is Cochlear Bone Anchored Solutions; received from August 2015 to August 2026. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.

153 reports arrived in the 12 months to August 2026, up 19% from 129 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 (99.4%) and malfunction (0.6%); across all hearing aid, bone conduction reports (product code LXB) death is recorded in 0% and malfunction in 0.6%. 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 (16.1%), expulsion (4.7%) and insufficient device problem information (2.6%). The patient problems coded most often are appropriate clinical signs, symptoms and conditions term/code not available, pain and tissue breakdown. 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."
