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 identified no other similar incidents from this lot.The investigation determined the reported difficulties appear to be related to circumstances of the procedure as it is likely that interaction with the calcified anatomy and/or other devices prevented the shaft lumens from moving freely; thus, resulting in resistance when pulling back the handle and the difficulty deploying the stent.There is no indication of a product quality issue with respect to manufacture, design or labeling.
