(b)(6).During a stent graft procedure in an abdominal endovascular aneurysm repair (evar) case, a powerflex pro balloon catheter was used for post dilation in the iliac artery, however it ruptured at eight atmospheres (atm) during its second inflation.There was no patient injury.The powerflex was replaced with a same-size competitor's balloon catheter and the procedure was completed.The target lesion was the iliac artery with moderate tortuosity and no calcification.The device prepped according to the instructions for use (ifu).There were no difficulties removing the product from the hoop, the protective balloon cover, the stylet or any of the sterile packaging components.There were no kinks or other damages noted prior to inserting the product into the patient.A competitor's inflation device was used.The inflation device was successfully used with other devices.There was no resistance/friction while inserting the balloon through the rotating hemostatic valve or the guide catheter.The catheter was never in an acute bend.The product was removed intact (in one piece) from the patient.No other information was provided.The device was not returned for analysis as it was discarded in the hospital.A product history record (phr) review of lot 17593779 revealed no anomalies or non-conformances during the manufacturing and inspection processes that can be associated with the reported event.Without the return of the device for analysis, the reported ¿balloon-burst - at/below rbp¿ could not be confirmed and the exact root cause could not be determined.Vessel characteristics (moderate vessel tortuosity) and/or procedural factors may have contributed to the reported event.According to the safety information in the instructions for use (ifu), which is not intended as a mitigation of risk, ¿if resistance is met during manipulation, determine the cause of the resistance before proceeding.Balloon pressure should not exceed the rated burst pressure.The rated burst pressure is based on the results of in vitro testing.At least 99.9% of the balloons (with a 95% confidence), will not burst at or below their rated burst pressure.Use of a pressure monitoring device is recommended to prevent over pressurization.Use only the recommended balloon inflation medium.Never use air or any gaseous medium to inflate the balloon.Prior to angioplasty, the catheter should be examined to verify functionality and ensure that its size and shape are suitable for the specific procedure for which it is to be used.¿ neither the phr review nor the information available suggests a design or manufacturing related cause for the reported event; therefore, no corrective/preventive action will be taken at this time.

During a stent graft procedure in an abdominal endovascular aneurysm repair (evar) case, a powerflex pro balloon catheter rupture was used for post dilation at the iliac artery; however it ruptured at eight atmosphere (8 atm) during its second inflation.There was no patient information.The powerflex was replaced with a same size competitor's balloon catheter and the procedure was completed.The target lesion is the in-stent iliac artery with moderate tortuosity and no calcification.There were no difficulty noted in the balloon during prep.There were no difficulties removing the product from the hoop, the protective balloon cover, the stylet or any of the sterile packaging components.There were no kinks or other damages noted prior to inserting the product the product into the patient.A competitor's inflation device was used.The inflation device was successfully used with other devices.There was no resistance/friction while inserting the balloon through the rotating hemostatic valve or the guide catheter.The catheter has never been in an acute bend.The product removed intact (in one piece) from the patient.The device was discarded in the hospital.No other information was provided.
