The returned sample was visually inspected and it was found to not have the thermistor in the oxygenator port as it should.There was also no evidence of chemical presence in the empty port.Review of the product's dhr found that the specific serial number of the returned sample had passed final visual inspection, confirming that the thermistor had been present in the port at the time of packaging.It is likely that the thermistor had been inserted into the port of the oxygenator, but never dipped into the chemical to bond it into the port, allowing it to come loose and not be present at the time of use.A retention sample from the same product code/lot number combination was visually inspected and confirmed to have a thermistor properly bonded within the oxygenator port.All available information has been placed on file in quality management for appropriate tracking, trending, and follow-up.
