(b)(4).Evaluation summary: the device was returned for analysis.The reported hub crack and leak was confirmed.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 similar incidents from this lot.There was no damage or leak noted to the stent delivery system (sds) during the inspection prior to use or during preparation of the device.The investigation determined the reported difficulties appear to be related to circumstances of the procedure as it is likely the sds was overly torqued during attachment to the inflation device resulting in the reported hub crack and subsequent hub leak.There is no indication of a product quality issue with respect to manufacture, design or labeling.

It was reported that the procedure was to treat a 90% stenosed lesion in the mid left anterior descending artery.A 3.25x12mm xience alpine stent delivery system (sds) was prepped without issues.The sds was advanced; however, when the device was being pressurized it was noted that contrast was leaking out of the hub.The pressurization was stopped and all connections were confirmed to be tight.The connections were fine; however, there was a crack at the hub.The sds was removed from the patient anatomy without issues and once outside the anatomy, the balloon appeared as if it had never been inflated.The procedure was successfully completed with a new 3.25x12mm xience alpine sds.There were no adverse patient effects and no clinically significant delay in the procedure.No additional information was provided.
