The device was not returned for analysis.A review of the lot history record and complaint history could not be conducted because the lot number was not provided.The investigation was unable to determine a conclusive cause for the reported difficult or delayed activation (difficulty to deploy); however, factors that may contribute to difficulty to deploy include but are not limited to damage to the device, contamination in the inflation lumen, patient anatomical morphology, patient disease state, inflation technique, contrast dilution, and inadequate connection to the inflation device.The reported patient effect of thrombosis is listed in the xience sierra everolimus eluting coronary stent systems instructions for use as a known patient effect of coronary stenting procedures.The reported patient effect of thrombosis and the reported treatment appears to be related to operational context of the procedure.There is no indication of a product quality issue with respect to manufacture, design or labeling.

It was reported that the procedure was performed to treat a 99% stenosed lesion in the mid left anterior descending artery (lad).On (b)(6) 2020, the patient presented with st-elevation myocardial infarction.Following pre-dilatation, a 2.5x18mm xience sierra stent was deployed; however, the stent was undersized for the vessel diameter and looked under expanded/irregular.No post-dilatation was performed, and the procedure was completed.On (b)(6) 2020, the patient went back to the cath lab due to the lad being occluded.An angiogram was performed and confirmed the occlusion to be thrombosis.The lesion was dilated, and the flow was restored.The patient is doing well.No additional information was provided.
