FDA (Devices) recall action 97750
The FDA (Devices) publishes a recall like this one as 4 separate product records. They share a firm, a date and a cause; this page is all of them in one place, so the scale of the action is visible rather than spread across 4 pages.
There is a potential safety issue associated with the magnet venting paths of the Siemens 3 Tesla MRI system within your IMRIS Operating Suite. Siemens notified IMRIS that an ice blockage may exist within the magnet venting system. In the event of a quench, helium gas may be unable to escape through the designed vent paths, leading to a pressure build-up within the helium containment system which could ultimately rupture the helium containment system, potentially resulting in a helium leak into the scanning room.
The agency’s own wording, quoted from the enforcement report.
IMRIS is recalling the IMRIS iMRI 3T V Operating Suite because an ice blockage in the Siemens 3 Tesla magnet's venting system could rupture the helium containment system during a quench. The FDA classified it Class I.
IMRIS is recalling the IMRIS iMRI 3T S Operating Suite because an ice blockage in the Siemens 3 Tesla Skyra magnet's venting system could rupture the helium containment system during a quench.
IMRIS is recalling the InVision 3T Operating Suite because an ice blockage in the Siemens 3 Tesla Vida magnet's venting system could rupture the helium containment system during a quench.
IMRIS is recalling the Neuro III-SV iMRI and iMRX systems because an ice blockage in the Siemens 3 Tesla Verio magnet's venting system could rupture the helium containment system during a quench.
