Reportable based on device analysis completed on 16-sep 2020.It was reported that inflation failure occurred.The 90% stenosed, 20mm x 4.5mm target lesion was located in the mildly tortuous and severely calcified right coronary artery.A 3.5mm x 15mm quantum maverick balloon catheter was advanced for dilatation.However, during procedure the physician found the stent could not stick well to the vessel as the balloon failed to inflate.The procedure was completed with another of same device.There were no patient's complications nor injuries reported and the patient's status was stable.However, returned device analysis revealed shaft detached/separated.
