A visual and functional inspection was performed on the returned device.The reported leak/splash was confirmed.Production record and corrective and preventative actions (capa) reviews were performed and revealed no indication of a product quality issue.Additionally, a query of the complaint handling database for the reported lot revealed there is no indication of a lot specific issue.Based on the reported information and the observations from the returned analysis, a definitive cause for the reported leak/splash could not be determined.Factors that may contribute to a leak include, but are not limited to, inflation technique, contrast concentration, loose connection with the indeflator, contamination in the inflation lumen, interaction with accessory devices, or damage to the balloon, guide wire and/or inflation lumen.In addition, it was reported the 3.0x12 mm xience skypoint stent delivery system (sds) was advanced to the lesion and air removal was attempted prior to positioning at the lesion.It should be noted that the xience skypoint, electronic instructions for use (eifu) 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 eifu deviation(s) directly caused or contributed to the reported event.In this case, it is possible the device may have interacted with the mildly tortuous, 90% stenosed lesion and/or accessory devices causing the observed material damage to the inner/outer member, ultimately causing the reported leak/splash; however, based on the information received and analysis of the returned device, a conclusive cause for the reported leak/splash cannot be determined.Based on the results of the complaint investigation, there is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.
