We have not received the complaint device for evaluation.However, we have confirmed the reported incident based on the picture of the balloon provided to us by the hospital.The balloon inflated on only side of the lumen.Our manufacturing team does conduct 100% inspection on each device and test them for balloon functionality.Each of the balloons are inflated with air using a syringe and then inspected to ensure balloons inflate concentric.At this time, we could not conclusively determine the root cause of the defect.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.In fact, this is the first and only complaint we have received of this nature in the lifetime of this device.We have not seen any adverse or upward trend relating to this attribute.Hence, no corrective action is required at this time.
