Complaint conclusion: as reported, 8mm x 4cm x 80cm powerflex pro percutaneous transluminal angioplasty (pta) balloon catheter was used; however, it ruptured at four atmospheres (atm).There was no reported patient injury.The product was returned for analysis.A non-sterile powerflex pro 6mm4cm 80 was received for analysis coiled inside a plastic bag.Per visual analysis of the unit, the balloon appears to have been previously inflated.The unit was thoroughly inspected at naked eye and no other anomalies were observed.Per functional analysis, balloon inflation testing was performed.The balloon was inflated successfully at 15 atm (device¿s rated burst pressure) with the inflator device; neither a leakage nor a burst was observed on the balloon.A product history record (phr) review of lot 82189355 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¿ was not confirmed through analysis of the returned device.The exact cause of the reported burst could not be determined.Per functional analysis of the balloon, there was no leakage or rupture noted upon inflation during functional analysis.The device performed as intended and maintained positive pressure up to 15atm¿s, the device¿s rbp.It is likely that procedural factors and handling of the device contributed to the event reported by the customer.Therefore, based on the information available for review it is difficult to draw a clinical conclusion between the device and the reported event.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.
