A powerflex pro 7mm x 2cm x 80cm was inserted and inflated; however, it ruptured at six atmospheres.The rupture occurred within its nominal pressure and during initial inflation.There were no reported patient injuries.The lesion was the common iliac artery and it was heavily calcified.Rupture was confirmed by contrast media leakage.The powerflex pro was replaced with another high-pressure balloon, and the procedure was completed.The product was not returned for analysis.A product history record (phr) review of lot 82147752 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.With the limited information available and without return of the product for analysis, it is difficult to draw a clinical conclusion between the device and the reported event.However, vessel characteristics of heavy calcification may have contributed to the reported event, as it is known that calcium may damage balloon material.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/preventive action will be taken at this time.
