A visual and functional inspection was performed on the returned device.The reported material rupture 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 other incidents.It was reported that the sds was not prepared (air aspiration) outside the anatomy.It should be noted that the xience skypoint, everolimus eluting coronary stent system (eecss), electronic instructions for use states: prepare an inflation device / syringe with diluted contrast medium.Attach an inflation device / syringe to the stopcock; attach to the inflation port.With the tip down, orient the delivery system vertically.Open the stopcock to delivery system; pull negative for 30 seconds; release to neutral for contrast fill.Close the stopcock to the delivery system; purge the inflation device / syringe of all air.Repeat steps until all air is expelled.It is unknown if the ifu deviation directly caused or contributed to the reported event.A conclusive cause for the reported material rupture could not be determined; however, the subsequent treatment appears to be related to the operational context of the procedure.Factors that may contribute to material ruptures include, but are not limited to, material damage, materials, inflation technique, interactions with other devices, lesion calcification and tortuosity or insufficient preparation prior to use.There was no damage noted to the stent delivery system (sds) during the inspection prior to use which suggests a product quality issue did not contribute to the reported difficulties.In this case, it is possible that interaction between the device and accessory devices and/or the patient anatomy may have caused the observed scratches on the balloon material, ultimately causing the reported material rupture; however, this cannot be confirmed.There is no indication of a product quality issue with respect to manufacture, design, or labeling.Na.
