As reported, the balloon of a 6mm x 20mm x 80cmpowerflex pro percutaneous transluminal angioplasty (pta) balloon catheter (bc) ruptured within its nominal pressure during its initial inflation.Therefore, the device was replaced with another non-cordis balloon catheter and the procedure was completed.There was no reported patient injury.The target lesion was the iliac artery.The lesion had severe calcification.There was mild vessel tortuosity with ninety percent (90%) stenosis.The device was not used for a chronic total occlusion (total occlusion >3 months).Initially, this was an endovascular therapy (evt) case.The device was stored and handled as per the instruction for use (ifu).There were no damages noted to the packaging of the device prior to use.The device was prepped according to the 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 device was prepped normally.A non-cordis contrast media was used in the procedure.A non-cordis inflation device was used and the same indeflator used successfully with other devices.There was no resistance/friction while inserting the balloon through the rotating hemostatic valve.There was no resistance/friction while inserting the balloon through the guide catheter.The balloon burst on its initial inflation within its nominal pressure.The product was removed intact (in one piece) from the patient.The procedure was completed using another non-cordis balloon catheter.The device will not be returned as it was discarded.Additional procedural details were requested but are unknown.
