326 medical device reports received by FDA name the brand "NT821731C, EDS 3, GEN ll, NO CATHETER" (nt821731c eds 3 gen ll no catheter); the manufacturer given most often on reports is Natus Medical; received from January 2021 to August 2026. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.

127 reports arrived in the 12 months to August 2026, up 15% from 110 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 (97.9%) and injury (2.1%); across all shunt, central nervous system and components reports (product code JXG) death is recorded in 0.9% and malfunction in 31.2%. Event type is the reporter's classification of the report, not a verified outcome.

The device problems coded most often are break (66%), crack (14.7%) and leak/splash (12%). The patient problems coded most often are bacterial infection, cardiac arrest and cerebrospinal fluid leakage. 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."
