The user has discarded the device since it was used on a patient with an infectious disease.Hence, we could not conclusively determine the root cause of the incident.The surgeon used the catheter to remove the clot in a dialysis patient.According to the surgeon, there was no stenosis or calcification around the region where the catheter was operated.After the first pass, he observed the saline that was inside the balloon started leaking from the distal end of the balloon.The surgeon did not experience resistance when removing the clot.Our review of the lot history records for this lot did not find any discrepancies either in the manufacturing or packaging process that could be related to this incident.Further, we have not received any other complaints of a similar nature for devices from this lot.There was no harm to the user because of the balloon malfunction.The surgeon used another catheter to complete the procedure.
