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 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 interaction with the heavily calcified, moderately tortuous and 85% stenosed anatomy resulted in compromising the stent such that during inflation resulted in the reported unintended system motion (stent dislodged during inflation).The treatment appears to be related to the operational context of the procedure as a 2.25x18mm xience xpedition stent was implanted over the first stent, which was at least partially in the target lesion.There is no indication of a product quality issue with respect to manufacture, design or labeling.Na.

It was reported that the procedure was performed to treat a lesion in the heavily calcified, moderately tortuous, 85% stenosed distal left anterior descending coronary artery.A 2.25x18mm xience xpedition stent dislodged during inflation, so a 2.25x18mm xience xpedition stent was implanted over the first stent, which was at least partially in the target lesion.There were no adverse patient sequelae and no clinically significant delay in the procedure.No additional information was provided.
