The actual device was not returned for evaluation; however a photograph of the event was provided by the user facility.Upon inspection of the provided photo, it was confirmed that the purge line was missing the small white clamp, and the line was being clamped off by hemostats.A retention sample from the same product code/lot number combination was visually inspected and confirmed to have the white clamp present on the purge line.As the clamp is assembled between the vernay valve and the l-shaped connector, it would have to be placed onto the line during the purge line assembly process.The likely cause of the clamp missing from the line is that it had not been properly placed onto the purge line during assembly.A review of the device history record revealed no production related anomalies.(b)(4).All available information has been placed on file in quality management for appropriate tracking, trending and follow-up.
