(b)(4).Evaluation summary: the device was returned for analysis and a visual inspection was performed on the returned device.The stent dislodgement was confirmed.The loose stent was unable to be confirmed as the stent was not returned.The failure to advance could not be replicated in a testing environment as it was based on operational circumstances.The difficulty removing the protective sheath could not be replicated in a testing environment due to the condition of the returned device.The investigation was unable to determine a conclusive cause for the reported difficulties removing the protective sheath however the reported physical resistance and loose / dislodged stent appear to be related to circumstances of the procedure.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 of the reported lot did not indicate a lot specific quality issue.Based on the information reviewed, there is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.
