(b)(4).There was no reported device malfunction.It is indicated that the device is not returning for evaluation; therefore, a failure analysis of the complaint device could not be completed.A review of the lot history record revealed no non-conformances that would have contributed to the reported event.Dissection is listed in the xience prime everolimus eluting coronary stent systems instructions for use (ifu) as a known patient effect of coronary stenting procedures.Although a conclusive cause for the reported patient effects, and the relationship to the product, if any, cannot be determined, there is no indication of a product quality deficiency with respect to manufacturing, design or labeling.Based on the information reviewed, there is no evidence to indicate the presence of a product deficiency.
