(b)(4).The device was not returned for evaluation.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.Based on the information reviewed, there is no indication of a product quality issue.The reported patient effect of intimal dissection is listed in the xience prime small vessel (sv), everolimus eluting coronary stent system, instructions for use (ifu) as a known patient effect of coronary stenting procedures.A review of the xience prime label attached to the lot history record for this lot was conducted indicating a manufacturing date of 02-may-2017 with an expiration date (use by date) of 01-may-2020.The product was used after expiration as it was reported the procedure occurred on (b)(6) 2020.The expiration date of the product is important for sterility, efficacy, and performance of the device.It should be noted that the xience prime sv, ifu states: note the product use by (expiration) date specified on the package.It is unlikely the ifu deviation of device expiration issue contributed to the reported patient effects.A conclusive cause for the reported patient effect(s), and the relationship to the product, if any, cannot be determined; however, the subsequent treatment appears to be related to the operational context of the procedure.There is no indication of a product quality issue with respect to manufacture, design or labeling of the device.
