It was reported that bd intima-ii¿ iv catheter was placed (b)(6) 2016 to the left forearm.It was not a repeat puncture and there was nothing abnormal noted during insertion or previous infusions and flushing.On (b)(6) 2016 at 9:30 am, the patient was getting undressed and found the catheter hub had detached from the insertion point but he didn't realize that the catheter had broken.At approximately 10:30 am, when the nurse was checking the ward and preparing the infusion for the patient, she found the iv was not on the patient's hand.The patient then returned the catheter hub to the nurse and she realized the catheter had broken.The patient received an x-ray and a full body ct scan but the missing catheter piece was not detected.Per assessment of the catheter remaining in the hub, the head nurse and doctor thought the broken section was smooth and they didn't believe the catheter could be damaged as a result of the patient undressing.The patient was discharged on (b)(6) 2016 without any further complaints or adverse symptoms.

Device evaluation: result - a review of the device history record revealed no abnormalities during the manufacture of the reported lot number 5198307.One used sample without the original packaging was received for evaluation on 1/8/2016.Observation under microscope revealed the needle has been pulled out and the catheter is broken.The site of the catheter breakage is about 1.5mm from the catheter adapter.The broken section is not smooth, has a burr, and no obvious stretching is observed.Because the catheter of the returned sample is too short, inside diameter, outside diameter, and tension testing cannot be performed.Catheter pull testing was performed in a vertical direction on retention samples of the same lot number.The broken catheter section of the retention sample is different than the broken section of the returned sample.A pull test on a catheter which was pierced through by a needle was performed on retention samples of the same lot number.The broken catheter section shows an obvious v-shape, which is different than the broken section of the returned sample.A pull test on a catheter which was bent 20 times at 180 degrees was performed in the vertical direction on retention samples of the same lot number.The broken catheter section of the retention sample is again different from the returned sample.Conclusion- the defect was not found to be manufacturing related.Out-going inspection of the reported lot 5198307 is qualified.The separating force test between catheter and catheter adapter meets requirements.No similar defect as the returned sample was found after simulating three conditions which may lead to a broken catheter.From the complaint feedback, no abnormality was found during previous infusion and flushing so the complaint cannot be confirmed.The customer's reported defect may have been caused by the patient when undressing.
