The device was not returned for analysis.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.Additionally, a review of the complaint history identified no indication of a lot specific product quality issue.The investigation could not determine the cause of the reported poor operability and torn tip.It may be possible that the tip was inadvertently damaged due to excessive force or it may be damaged due to interaction with an accessory device (such as introducer, hemostasis valve, etc.); however, without having the device examined, this could not be confirmed.There is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.
