Complaint conclusion: as reported, the 5mm 20cm 155 saber rx percutaneous transluminal angioplasty (pta) balloon catheter ruptured at eight atmospheres (atms) during its initial inflation when it was used after an unknown guide wire crossed the lesion.Therefore, the device was replaced with another 5mm 100cm saber rx balloon catheter and the procedure was completed.There was no patient injury.The product looked normal when removed from its packaging.The device prepped normally (i.E.Maintain negative pressure).The access site location was the left femoral.The target site had little tortuosity and 80% stenosis.There was no difficulty removing the product from the hoop, the protective balloon cover, or the stylet or any of the sterile packaging components.There were no kinks nor other damages noted prior to inserting the product into the patient.A non-cordis inflation device was used.The same indeflator was used successfully with other devices.There was no resistance/friction while inserting the balloon through the rotating hemostatic valve.The device was not used for a chronic total occlusion (total occlusion >3 months).The device did not have to pass through a previously placed stent.The product was removed intact (in one piece) from the patient.There were no other anomalies noted when the device was removed from the patient.The product was not returned for analysis as it was discarded due to hepatitis c.A product history record (phr) review of lot 82193119 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 80% stenosis may have contributed to the reported event, as a heavily stenosed lesion may damage balloon material when attempting to cross the lesion.However, without the return of the device for analysis it is difficult to draw a clinical conclusion between the device and event reported.According to the warnings in the safety information in the instructions for use ¿prior to angioplasty, the catheter should be examined to verify functionality and integrity, and ensure that its size and shape are suitable for the specific procedure for which it is to be used.Do not use if product damage is suspected or evident.To reduce the potential for vessel damage or the risk of dislodgement of particles it is very important that the inflated diameter of the balloon should approximate the diameter of the vessel just proximal and distal to the lesion.The balloon dimensions are printed on the product label.The compliance table incorporated with the product shows how balloon diameter increases as pressure increases.Do not exceed the rated burst pressure recommended on the label.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.Pressure in excess of the rated burst pressure can cause balloon rupture and potential inability to withdraw the catheter through the introducer sheath.Balloon rupture can cause vessel damage and the need for additional intervention.Use only the recommended balloon inflation medium (a 50/50 mixture by volume of contrast medium and normal saline).Never use air or any gaseous medium to inflate the balloon.¿ 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.
