The mozec balloon was opened and passed off to the scrub tech and was prepped and placed on the wire.Once the balloon was placed into the blockage and inflated it wouldn't hold pressure.The balloon was removed and the scrub tech noticed there was a hole in the shaft and it was leaking.As reported, after the 2.00 x 12 mozec balloon was placed into the blockage and inflated, the balloon was not able to hold the pressure.Upon removal of the balloon, a hole was noted in the shaft and from where there was a leakage.Patient was male, weighing 200 pounds.The target lesion was ostial marginal with 90% stenosis and the vessel diameter was 2.5 mm.The lesion was moderately calcified and little tortuous.The device was not used for chronic total occlusion.The device was stored and handled as per the ifu.There was no damage noted to the packaging of the device.There was no difficulty in removing the product from the packaging.There was neither any difficulty in removing the product from the hoop, nor in removing the protective cover.The device was prepped as per the ifu during which no leakage was observed.The product was inspected prior to use and appeared to be normal.There were no kinks or other damages noted prior to the insertion of the product into the patient.There was no resistance/friction while inserting the balloon through the rotating hemostatic valve.There was no resistance/friction while crossing the target lesion.The balloon did not inflate normally.The maximum inflation was 7 atm, after which the pressure dropped.The product was removed intact from the patient and the procedure was completed with another balloon.No patient injury was reported.
