Manufacturer Narrative

The filiform double pigtail ureteral stent was not expected or returned for an evaluation.Additionally, no photographs were provided.An autopsy report has been requested but has not been received.Without the actual device, an evaluation could not be performed and a definitive root cause of the stent separation cannot identified at this time.A review of production and quality documentation did not identify any specific issues with current manufacturing or quality controls that may have contributed to this incident.A review of the device history record showed there were no non-conformances identified during the manufacturing process that would have caused or contributed to the reported product issue.A review of complaint history for this product/lot number combination revealed that this is the only complaint received.Measures have been initiated to address this failure mode.A review of the instructions for use (ifu) noted the following precaution: "improper handling can seriously weaken the stent.Acute bending or overstressing during placement may result in subsequent separation of the stent at the point of stress after a prolonged indwelling period.Angulation of the wire guide or stent should be avoided.Use of a 0-degrees scope lens is recommended.Scope larger than 21.0 french are suggested.Individual variations of interaction between stents and the urinary system are unpredictable." cook medical will notify the appropriate personnel and continue to monitor for similar complaints.Per the quality engineering risk assessment no further action is required.
