As reported, the balloon of a 6mm x 4cm x 80cm powerflex extreme percutaneous transluminal angioplasty (pta) balloon catheter (bc) ruptured while attempting to treat a stenosed cephalic vein.The balloon was delivered without complication and removed without incident (intact).There was no harm caused to the patient.The device was stored in the cath lab hanging from a mounted rack in a cabinet in a temperature-controlled room, for less than six months.The device was stored, handled and prepped per the instructions for use (ifu).The device was prepped normally by maintaining negative pressure.There was no difficulty removing the product from the hoop and there was no difficulty removing the protective balloon cover.There was no difficulty removing the stylet or any of the sterile packaging components.The contrast media used was ge omnipaque and the contrast to saline ratio was 50/50.The same indeflator was used successfully with other devices.There were no kinks or other damages noted prior to inserting the product into the patient.The target lesion was the focal stenosis in the cephalic vein.The lesion was not calcified and there was little vessel tortuosity.There was eighty percent stenosis.The device was not used for a chronic total occlusion.The procedure was completed with a non-cordis product.The device will not be returned for analysis as it was discarded.

After further review of additional information received the following sections g3, g6, h2 and h6 have been updated accordingly.As reported, the balloon of a 6mm x 4cm x 80cm powerflex extreme percutaneous transluminal angioplasty (pta) balloon catheter (bc) ruptured while attempting to treat a stenosed cephalic vein.The balloon was delivered without complication and removed without incident (intact).There was no harm caused to the patient.The device was stored in the cath lab hanging from a mounted rack in a cabinet in a temperature-controlled room, for less than six months.The device was stored, handled and prepped per the instructions for use (ifu).The device was prepped normally by maintaining negative pressure.There was no difficulty removing the product from the hoop and there was no difficulty removing the protective balloon cover.There was no difficulty removing the stylet or any of the sterile packaging components.Non-cordis contrast media was used and the contrast to saline ratio was 50/50.The same indeflator was used successfully with other devices.There were no kinks or other damages noted prior to inserting the product into the patient.The target lesion was the focal stenosis in the cephalic vein.The lesion was not calcified and there was little vessel tortuosity.There was eighty percent stenosis.The device was not used for a chronic total occlusion.The procedure was completed with a non-cordis product.The device was not returned for evaluation as it was discarded.A product history record (phr) review of lot 82187213 revealed no anomalies or non-conformance's during the manufacturing and inspection processes that can be associated with the reported event.The reported ¿balloon burst¿ 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 as the target lesion was noted to be a focal 80% stenosed cephalic vein.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.
