As reported, the balloon of a powerflex pro 8mm4cm 80 percutaneous transluminal angioplasty (pta) dilation catheter ruptured at four atm in an endovascular aneurysm repair procedure.The device was replaced with an unknown balloon catheter to complete the procedure.No injury was reported to the patient.The device was prepped per the instructions for use (ifu).The product was stored properly according to the ifu.There was no difficulty removing the product from the hoop or removing the protective balloon cover.There was no difficulty removing the stylet or any of the sterile packaging components.The device prepped normally and maintained a negative pressure.There were no kinks or other damages noted prior to inserting the product into the patient.Other procedural details were requested but not provided.The product was not returned for analysis as it was discarded due to suspicion of infectious disease.A product history record (phr) review of lot 82178227 revealed no anomalies or non-conformances during the manufacturing and inspection processes that can be associated with the reported event.The reported ¿balloon burst - at/below rbp¿ could not be confirmed as the device was not returned for analysis.The exact cause could not be determined.Vessel characteristics, although unknown, may have contributed to the reported event.However, with the limited amount of information provided and without the return of the device for analysis, it is difficult to draw a clinical conclusion between the device and the event reported.According to the safety information in the instructions for use, ¿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 nor the information available suggests a design or manufacturing related cause for the reported event.Therefore, no corrective or preventive action will be taken at this time.
