As reported, the 9mm x 4cm x 135 powerflex pro percutaneous transluminal angioplasty (pta) balloon catheter was used.However, there was difficulty crossing the lesion and the balloon ruptured due to severe calcification.There was no reported patient injury.The device was removed and another unknown device was used to complete the procedure.The target lesion is the iliac artery.The device was not used in a chronic total occlusion case within three months.There were no difficulty noted in the balloon during prep.There were no difficulties removing the product from the hoop, the protective balloon cover, the stylet or any of the sterile packaging components.A competitor's contrast media and inflation device were used.There was no resistance/friction while inserting the balloon through the vessel.There was difficulty crossing the lesion.The catheter has never been in an acute bend.The plunger was depress into the syringe/indeflator when trying to inflate.The device will not be returned for evaluation because it was discarded by mistake.No other information was provided.
