During use, the maxi ld balloon catheter ruptured at six atmospheres (6atm).There was no patient injury.The lesion was the abdominal aorta which had ninety percent (90%) stenosis and was not calcified.A maxi ld balloon was inserted after a guidewire crossed the lesion.The maxi ld balloon was delivered to the lesion.It was used per the instruction for use (ifu).However, the pressure was not raising after the maxi ld balloon was inflated at 6atm.Therefore, the maxi ld balloon was removed from the patient and confirmed the balloon rupture.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 and the guide catheter.There was no difficulty crossing the lesion.The catheter has never been in an acute bend.The product removed intact (in one piece) from the patient.The product was not returned for analysis.A product history record (phr) review of lot 17729387 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 of ninety percent stenosis may have contributed to the reported event.This narrowing of the vessel makes it difficult for the catheter to cross the lesion, it is likely that when attempting to cross, the balloon material was damaged.However, without the return of the device we are unable to draw a clinical conclusion between the device and reported event.According to the safety information in the instructions for use ¿note: the rated burst pressure is printed on the package label.In vitro testing has shown that with 95% confidence, 99.9% of the balloons will not burst at or below the rated pressure.Balloons should not be inflated in excess of the rated burst pressure.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.Carefully advance the catheter through a sheath or through the percutaneous entry site.Note: gentle counterclockwise rotation of the balloon may ease introduction through the sheath or percutaneous entry site.Note: perform all further catheter manipulations under fluoroscopy.Carefully advance the catheter to the selected site.Caution: if strong resistance is met during advancement or withdrawal of the catheter, discontinue movement and determine the cause of resistance before proceeding.If the cause of resistance cannot be determined, withdraw the entire system.¿ 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.
