The returned device was examined.The wire and polymer tip were examined under magnification and no issues of burrs or other defects were found.The polymer tip was manipulated with no unusual stiffness.The laceration of the vessel may have occurred due to patient physiological factors, or if a defect was present, it may have been removed during a cleaning process of the sample (fibrous material resembling cotton was found on the tip during the sample evaluation).No manufacturing defects were observed.
