We have not yet received the complaint device for evaluation from the hospital.Hence, at this time, we could not determine the cause of this failure.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.As part of our manufacturing process, a 100% balloon and winding inspection are performed on each of the manufactured product to ensure each catheter operates properly.We have also performed pull test on a sample of units from this lot number during our in-process inspection.All of these units passed the test requirements when the balloons were pull tested to their validated force.The arterial embolectomy catheter is not recommended for the removal of fibrous, adherent or calcified material ( eg.Chronic clot, atherosclerotic plaque ).This catheter is not designed to withstand the additional pull force needed to remove these materials.Our sales rep.And the distributor had reached out to the contact person at the hospital for additional information regarding the incident.However, we have not received any response back from the contact person yet.We have implemented a corrective and preventive action (capa) to address similar issues and prevent them from reoccurring.As part of the capa, we have already made adjustments to the process which should improve the reliability of the ligature windings.
