The device was returned for analysis.The reported tip material separation was able to be confirmed.The reported difficult to remove and the reported stretched stent were unable to be replicated in a testing environment as they was based on operational circumstances.The lot history record (lhr) and corrective and preventive actions (capa) reviews were performed and revealed no indication of a product quality issue.Additionally, a review of the complaint handling database identified no other incidents from this lot.As there was no damage noted to the device during the inspection prior to use, the investigation determined the reported difficulties appear to be related to circumstances of the procedure as it is likely that the nose cone inadvertently became caught on the deployed stent resulting in the reported difficult to remove.Interaction/manipulation of the compromised device resulted in the reported stretched stent and ultimately resulted in the reported tip separation/noted tip jacket and inner member separations and the noted bent stabilizing shaft.As reported, the stent was deployed in the target lesion and the nose cone was snared from the patient.Based on the reported information and results of the complaint investigation there is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.
