Visual inspection, functional testing, and dimensional analysis were performed on the returned device.The reported difficulty to flush could not be confirmed.There was dried contrast within the sheath.Due to device conditions, the catheter was placed into the ultrasonic water bath to remove dried contrast.After several days, the catheter was able to be purged; however, there was a leak and tear noted on the side-arm tubing.It is unknown what caused the tear and if the noted tear could contribute to the reported issue.The dimensional analysis performed on the purge hole of the device also presented that the catheter was within specification.A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.Additionally, a review of the complaint history identified no indication of a lot specific product quality issue.Based on the reported information and analysis of the returned unit, the cause of the reported difficulty to flush could not be determined.It is unknown if the noted tear could contribute to the reported issue; however, the noted tear on the side-arm tubing was determined to be a potential product quality issue.The issue is being addressed per internal operating procedures.Abbott vascular will continue to trend the performance of these devices.Return analysis noted a tear on the side arm tubing.Additional review of the location of the tear determined that the device component (side arm tubing) does not enter the patient and therefore, does not have the potential to result in foreign body and cause or contribute to serious injury.
