The 1st device was prepped, flushed with hep saline and amplatzer loaded to the delivery system and the device was flushed.When the device was deployed into the pulmonary artery it seemed misshapened and it would not allow for closure.The device was then removed from the patient the amplatzer tried to reshape and check the closure but didn¿t seem to work properly (lot number 8031289) another device was used, prepped in the same fashion.The 2nd device when loaded seemed like it wasn¿t tracking well on the delivery guide and the torque was hung up midway through, it was even forced a little to push it through but still was hung up.(lot # on 2nd device 7712846).Delivery and a 3rd device was used and worked.So, it was unknow if the devices were defective or the delivery was defective.(delivery lot # 8412603).
