FDA (Devices) recall action 74840
The FDA (Devices) publishes a recall like this one as 3 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 3 pages.
Due to an internal communication error between the firmware and the software of the components, the planned CT scan executes properly, but the injector is not started. Therefore, the contrast agent is not injected and the desired examination result is not achieved. This error only affects the automatic mode or coupled mode and does not affect the manual control of the injector.
The agency’s own wording, quoted from the enforcement report.
The unit total adds up the quantities the agency stated for each product. Where a product record gave no figure, or gave a weight rather than a count, it contributes nothing — so the real total is at least this, never less.
Siemens is recalling one SOMATOM Definition AS CT scanner because a software error prevents the automatic injection of contrast agent during scans.
Siemens is recalling two CT scanners where a software error prevents contrast agent injection during automatic scans, resulting in failed examinations.
Siemens is recalling four CT systems because a software error prevents the contrast agent injector from starting in automatic or coupled modes.
