A review of the device history record, which includes verification of all steps in the manufacturing of the pump, verification of all final testing performed by/on the pump, verification of sterilization, and packaging for subject pump was performed.The review did not identify any non-conformances, issues or capas associated with pump function.Device was returned for additional evaluation and investigation.Additional physical investigation was performed on the device, and the alleged issue was confirmed.Visual analysis confirmed the metal tip had been pulled from the rubber cannula on the cap.The metal tip was viewed under magnification, confirming the metal tip had been pulled from the compression sleeve it had been crimp collared to.This crimp collar has been failure strength axial tested.The result of the test found that they are able to resist an axial load of 1.1lb.Statistical analysis showed there is a 95% confidence that 95% of the values are above 9.4 lbs.The cause for the metal tip coming out the cannula is the inadvertent use of excessive force pulling on the catheter access port attachment, inadvertently pulling the metal tip out of the cannula.Internal complaint number: (b)(4).
