Event or Problem Description
Medtronic received information that prior to use of the affinity nt cardiotomy venous reservoirs (cvrs), it was reported that while separating the material to be sent to customers, it was observed that the plastic packaging where the material is found was marked and with a small tear.The second unit that was in the box was also broken.Upon inspection of the units that were being separated, all of them were noted to be torn or had holes.It was decided that all of the oxygenators in the facility would be inspected and out of the 6 batches, 4 were affected.Of the 600 oxygenators, approximately 168 units were out of service.There was no patient involvement, so no adverse effect occurred.One of the cradles where the oxygenator was located was slightly damaged, but in a distant place where the packaging was broken, but the cardboard boxes, where the two oxygenator units can be seen, were all intact.The vast majority of these boxes had not been opened, until authorized was given to inspect them.Medtronic received additional information that there were no devices or components missing or wrong in the package.The products were not used.
