As reported, the 6mm x 4cm x 80cm powerflex pro percutaneous transluminal angioplasty (pta) balloon catheter was used but it ruptured at 4 atmospheric pressure (atm).It was replaced with another device (unknown) and the procedure completed.There was no reported patient injury.The product looked normal when it was removed from its packaging.There was no difficulty removing the product from the hoop, protective balloon cover, stylet or any of the sterile packaging components.The device prepped normally.There were no kinks nor other damages noted prior to inserting the product into the patient.Additional procedural details were requested but are unknown.The device will not be returned for analysis as it was discarded.

As reported, the 6mm x 4cm x 80cm powerflex pro percutaneous transluminal angioplasty (pta) balloon catheter was used but it ruptured at four atmospheric pressure (atm).It was replaced with another device (unknown) and the procedure completed.There was no reported patient injury.The product looked normal when it was removed from its packaging.There was no difficulty removing the product from the hoop, protective balloon cover, stylet or any of the sterile packaging components.The device prepped normally.There were no kinks nor other damages noted prior to inserting the product into the patient.Additional procedural details were requested but are unknown.The product was not returned for analysis as it was discarded.A product history record (phr) review of lot 82182704 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.
