Results - a review of the device history record revealed no abnormalities during the manufacture of the reported lot number 5111723.Two samples were returned for evaluation and were inspected under visual/microscopic examination.One unused sample in the original, sealed package was received.There were no bends, holes, kinks, splits or wrinkles in the catheter tubing; nor the characteristic v shape of a spear through.The tubing did not separate from the adapter when the needle was retracted.A pull force test was performed and the sample passed specification.One used catheter/adapter assembly with an attached needleless connector was received in two portions.On the portion of the catheter attached to adapter, it was observed that there was approximately ¼ inch of catheter tubing protruding from the nose of the adapter.The piece of loose tubing was noted to be approximately ¾ inch long.The tubing edges are sharp, jagged, and in a v shape pattern.The adapter and the loose tubing were pieced back together and show that the v shape patterns align.Conclusion- the reported defect was confirmed with the returned unit.The evidence provided does not deliver confirmation that the catheter was not functioning correctly during the period of infusion.It is uncertain whether the defect observed was caused by use of sharp object or instrument, manipulation of the device prior to insertion, or by the manufacturing process.Therefore, an absolute root cause for this incident cannot be determined.
