Adverse-event reports (MAUDE)
Read this first: MAUDE report counts cannot be used to compute incidence rates or compare device safety. Reporting is incomplete, duplicated, and spikes with publicity; there is no denominator of devices in use. The peer line shows reporting volume for the average device in the same FDA product code — a reporting baseline, not a risk measure.

| 2025-08-28 | Z-2661-2025 | Class I | Open, Classified | There is a potential for an ice blockage to form or currently exist within the magnet venting system. In the event of a quench, helium gas may be unable to escape through the designed venting paths, leading to a pressure build-up within the helium containment system.
