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 revealed no other similar complaints reported from this lot.The investigation determined that the reported difficulty removing, material separation, damage caused to the implanted stent, and subsequent patient effects appear to be due to circumstances of the procedure.Based on the reported information, the tip of the catheter became stuck on the newly implanted stent post pci resulting in difficulty removing.As a result, damage to the stent strut occurred and the tip of dragonfly opstar catheter separated.Unexpected medical intervention was performed by placing another stent to embed the separated tip against the artery wall.Reportedly, the patient is doing well.There is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.Na.
