Received three (3) open, used list number 14687 plumsets for evaluation.The reported kinked tubing was confirmed by investigation in all of the returned sets.As received, multiple kinks were observed in the tubing.However, because all of the returned sets were received open, out of package, and used it is possible that the observed kinks were exacerbated during shipping to icu medical for investigative purposes or additional kinks were induced.Potential causes of the observed kinking is twisting of the tubing during coiling, the configuration of the set in the product package or the shipping container, or a combination thereof.All sets passed all functional tests per the product specifications and the observed kinked tubing did not affect product performance during investigative testing.The reported backflow was not confirmed by investigation.Backflow was not observed under conditions representative of correct use even when back pressure.Arterial pressure was applied to the plumset.Backflow was only replicated when an open line external to the plumset was present or the plum cassette was not inserted into the plum pump, the flow regulator was open, and an appropriate pressure differential existed.As no lot number was identified, a manufacturing batch record review, maintenance routines and maintenance work orders (wo) to this nature could not be performed.
