(b)(4).Evaluation summary: the device was returned for analysis with the shaping ribbon detached.The reported kink was able to be confirmed.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 other incidents from this lot.The investigation determined the reported difficulties appear to be related to circumstances of the procedure as it is likely that the guide wire was withdrawn from the dispenser coil at an angle at the exit port of the dispenser coil causing the reported/noted damages (kinked/bent core, stretched coils, bent/detached shaping ribbon).There is no indication of a product quality issue with respect to manufacture, design or labeling.
