As reported, the 5mm x4cm 80cm powerflex extreme percutaneous transluminal angioplasty (pta) balloon catheter ruptured during first inflation at approximately 8 atmospheres (atm).The procedure was completed without complications.There was no reported patient injury.The intended procedure was angioplasty.The device was stored and prepped per the instructions for use (ifu).There was no difficulty removing the product from the hoop.There was no difficulty removing the protective balloon cover.There was no difficulty removing 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.The catheter was never in acute bend.The device was prepped normally.A non-cordis contrast media was used with the 50% contrast to saline.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 target lesion was the cephalic vein.The lesion was not calcified, had no vessel tortuosity, had 80% of stenosis, and not a chronic total occlusion.There was no resistance/friction while inserting the balloon through the guide catheter.There was no difficulty advancing the balloon catheter through the vessel.There was no issue during delivery of the balloon to the target lesion.The device did not pass through a previously placed stent.The plunger was depressed into the syringe/indeflator when trying to inflate.The user was able to depress the plunger into the syringe/indeflator when trying to inflate.The balloon did not inflate normally.There was no unusual force used at any time during the procedure.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 device will not be returned for evaluation as it was already discarded.

After further review of additional information received the following sections g4, g7 ,h2,and h6 have been updated accordingly.The 5mm x 4cm 80cm powerflex extreme percutaneous transluminal angioplasty (pta) balloon catheter ruptured during first inflation at approximately eight atmospheres (atm).There was no reported patient injury.The intended procedure was an angioplasty.The target lesion was the cephalic vein.The lesion was not calcified, had no vessel tortuosity, had 80% of stenosis, and not a chronic total occlusion.The procedure was completed without complications.The device was stored and prepped per the instructions for use (ifu).There was no difficulty 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.The catheter was never in acute bend.The device was prepped normally.A non-cordis contrast media was used with the 50% contrast to saline ratio.A non-cordis inflation device was used successfully with other devices.There was no resistance/friction while inserting the balloon through the rotating hemostatic valve or through the guide catheter.There was no difficulty advancing the balloon catheter through the vessel.There was no issue during delivery of the balloon to the target lesion.The device did not pass through a previously placed stent.The plunger was depressed into the syringe/indeflator when trying to inflate.The user was able to depress the plunger into the syringe/indeflator when trying to inflate.The balloon did not inflate normally.There was no unusual force used at any time during the procedure.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 device was not returned for evaluation as it was discarded.A product history record (phr) review of lot 82177045 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 and procedural factors may have contributed to the reported event.The intended procedure was an angioplasty of the cephalic vein; arteriovenous shunts are often scarred and fibrous in nature and often resistant to balloon expansion increasing the likelihood of damage to the balloon.However, with the 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.According to the safety information in the instructions for use ¿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.
