Spellings of one product vary from report to report.
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 injury (86.9%), malfunction (12.2%) and death (0.9%); 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 obstruction of flow (21.7%), infusion or flow problem (9.5%) and other (for use when an appropriate device code cannot be identified) (8.6%). The patient problems coded most often are injury, failure of implant and other (for use when an appropriate patient code cannot be identified). 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."
